Why we are using antivirus to mobiles and pc’s

Anti-virus software is a program or set of programs that are designed to prevent, search for, detect, and remove software viruses, and other malicious software like worms, trojans, adware, and more.

These tools are critical for users to have installed and up-to-date because a computer without anti-virus software installed will be infected within minutes of connecting to the internet. The bombardment is constant, with anti-virus companies update their detection tools constantly to deal with the more than 60,000 new pieces of malware created daily.

There are several different companies that build and offer anti-virus software and what each offers can vary but all perform some basic functions:

  • Scan specific files or directories for any malware or known malicious patterns
  • Allow you to schedule scans to automatically run for you
  • Allow you to initiate a scan of a specific file or of your computer, or of a CD or flash drive at any time.
  • Remove any malicious code detected –sometimes you will be notified of an infection and asked if you want to clean the file, other programs will automatically do this behind the scenes.
  • Show you the ‘health’ of your computer

Always be sure you have the best, up-to-date security software installed to protect your computers, laptops, tablets and smartphones.

What’s the Best Malware Protection?

Which antivirus should you choose? You have a wealth of options. Kaspersky Anti-Virus and Bitdefender Antivirus Plus invariably rate at the top in independent lab tests. In my hands-on tests, Norton AntiVirus Basic outscored every other recent product except Webroot. A single subscription for McAfee AntiVirus Plus lets you install protection on all of your Windows, Android, Mac OS, and iOS devices. And its unusual behavior-based detection technology means Webroot SecureAnywhere Antivirus is the tiniest antivirus around. We’ve named these five Editors’ Choice for commercial antivirus, but they’re not the only products worth consideration. Read the reviews of our top-rated products, and then make your own decision.

Note that I reviewed many more antivirus utilities than I could include in the chart of top products. If your favorite software isn’t listed there, chances are I did review it. You can see all the relevant reviews on PCMag’s antivirus software page. All the software listed in this feature are Windows antivirus apps. If you’re a macOS user, don’t despair, however; PCMag has a separate roundup dedicated solely to the best Mac antivirus software.

Digital Devices to Enhance Nanotechnology


As technology advances, so does the need for more powerful and efficient power sources that can keep up with computing demands while remaining scalable and inexpensive. New nanotechnology innovations are opening the door to the technology of the future.
Nanoscale Memristor
Artificial neural networks are vital to developing computing abilities such as pattern recognition at levels on par with humans. Nanoscale devices called memristors (rhymes with ancestors) might be the answer to creating truly functional artificial brains. Memristors control power flow, remember charge, and are tiny and inexpensive. Scientists at the University of Southampton have shown that memristors can “learn” information without assistance and process data in real time, making them a potential foundation for the next generation of the Internet of Things.
Nanotube Transistors
The silicon carbon transistors found in conventional computer chips aren’t efficient enough to keep up with the performance requirements demanded by such chips. Nearly 20 years ago, nanotubes—minuscule rolls of carbon sheets—were discovered to be much more efficient. However, there have been several roadblocks to manufacturing functional nanotubes. To connect the nanotubes with the metal contacts needed to conduct energy, he created a new way to fuse them together at the nanotubes’ ends. IBM plans to replace silicon carbon transistors with nanotube transistors within the next decade, banking on much better performance at a fraction of the power use.
Microcable Power Textile
The next wave of electronics will require lightweight, efficient, and inexpensive power sources. Researchers at the Georgia Institute of Technology have created a potential solution: a textile that can produce power using nothing but the sun and human body motion.

The researchers used polymer fibers to make solar cells, and then wove the cells with fiber-based triboelectric nanogenerators (materials that become electrically charged when in contact with each other), which create energy from motion. The resulting fabric is only 320 micrometers thick—approximately one-third of a millimeter—and could be integrated into items such as tents and clothing to power devices like phones and wearables.


Testing for disease is often a race against time, especially when trying to prevent potential outbreaks, or when quick treatment is crucial. These nanotechnology devices enable testing that’s efficient, inexpensive, and quick, producing real-time results that could help to stop epidemics in their tracks.
Bimaterial Microcantilever
Modern medicine has made many once-endemic diseases, like polio and tuberculosis, rare. But sometimes bacteria and microorganisms mutate into “superbugs,” rendering conventional treatments ineffective. The World Health Organization calls antibiotic resistance one of the biggest threats to humans.

Quickly testing bacteria for drug resistance is crucial, but the usual ways to grow and test bacteria samples in a lab take time. Researchers at the University of Alberta have created a nanoscale device that can test samples on site, in real time.

The device captures bacteria from a sample using a minuscule cantilever, which sends the sample through a channel where receptors identify the bacteria type. The bacteria are then exposed to antibiotics, and the reaction indicates whether they are treatable or antibiotic-resistant. Another advantage, given that sometimes only minuscule samples are available: the device can be used to test samples millions of times smaller than a raindrop.
Testing for cancer and infectious diseases can currently mean waiting for hours before lab results are available. But researchers at the Henry Samueli School of Engineering and Applied Science, the California NanoSystems Institute, and the David Geffen School of Medicine collaborated to discover a faster method to test for the presence of proteins in body fluids that indicate cancer or other diseases.

The new test uses DNA nanotechnology—which exploits DNA’s chemical and physical attributes rather than its genes—to trigger a molecular chain reaction if disease-related proteins are present. The results appear in about 10 minutes, and the test can be done in a doctor’s office, removing the need for a separate hospital visit. The researchers have successfully tested for flu, with plans to test for diseases characterized by more complex protein structures. Eventually, they want to integrate the technology into a handheld reader, which could become the go-to device in every doctor’s office.

Why Enterprise Mobile Projects Need a Proof of Concept—Fast

To enterprise level product owners: mobile apps can seem like a no brainer, especially as custom solutions can be uniquely tailored and plug directly into the nuances of your workforce, operations and processes. Coming up with a great idea – however – does not always cut it. To secure buy-in and get a project up off the ground, that idea needs some meat on its bones – proof that the concept has tenable value and potential for long term success.

One common scenario: key internal stakeholders, generally at the C-level or above, don’t see the apparent value of a mobile app, so getting capital funding for the project becomes a major hurdle.

Google’s semantic search and the future of SEO

We know that SEO is constantly changing and evolving, mostly in response to two key factors: developments in how search engines work and developments in how websites work. One of the current challenges facing SEO is coming from the first of these categories – developments in how search engines work. And by ‘search engines’, what we really mean is Google.

The summary of the change is simple – Google is changing its search algorithm away from a solely keyword-based system to also include semantic search – but the consequences for SEO will take a little time to work out, although it is clear that it will become increasingly difficult to ‘game’ results with so-called black-hat SEO techniques (last year’s Panda update also aimed mainly to reduce the ranking of poorer websites – although what this category included was tricky to define and somewhat controversial with some legitimate businesses crippled by the changes).

The semantic search update will have the same goal – improving the quality of search results – but will go about it in a different way. Panda retained the focus on individual keywords for Google search, but just reconfigured how they were interpreted. Semantic search will be fundamentally different, focusing instead on the semantic relationships between search terms in order to establish user intent at a deeper level. As many have already pointed out, this is nothing new – semantic search has been around since 2008 – but it’s now being taken a lot more seriously for SEO with Google’s decision to introduce it.

It’s still early days for understanding the impact of these changes for SEO, but I feel confident in making one prediction regarding consequences of the changes.

Content which is designed to superficially match a search query – but is basically rubbish once a human actually looks at it – will hopefully, finally, be consigned to the dustbin of web history. In other words, those articles that try to boost SEO by name-dropping popular search terms in the title to attract traffic for something completely unrelated will no longer achieve anything – and will hopefully disappear.

So no more making reference to Barack Obama, Lady Gaga or David Beckham in an article about fly fishing, the weather or some other third-rate celebrity in order to boost traffic for this weak offering. No more lazy content designed only with the search ranking – and not the reader/user – in mind. This is surely a desirable goal and if semantic search builds on the earlier work of Panda, then it’s all good as far as I’m concerned. Anything which prompts content creators to look beyond individual keywords and work out at a deeper level what it is that users want should, presumably, deliver higher standards of content since the alternative (to drop down Google’s search ranking) will equate to a business disaster.

Best Medical Billing Services: Our Recommendations

Medical practices rely heavily on the effectiveness of their billing operations. Healthcare might be the top priority, but your medical practice is still a business and needs to make money to survive. As any healthcare professional knows, billing is complicated process with a number of opportunities for things to go wrong. From coding errors and processing delays to dealing with insurance companies and trying to track down unpaid patient accounts, billing departments have to balance a number of tasks and complete them all perfectly; otherwise, you might not get your money for already-rendered services on time, or at all.

In-house medical billing vs. outsourced revenue cycle management
If you opt to have your own staff cover medical billing, you’ll need practice management software to keep track of your patients’ balances and send bills to payers. You’ll also need a certified medical coder on staff to oversee the operation, and the practice will be responsible for responding to any rejections or denied claims.

It’s also crucial to stay on top of the ever-changing regulatory framework and new policies; for example, ICD-10 coding has largely been implemented across the industry. Keeping billing in-house is often cheaper and gives you more control over the process, but for a small practice that already needs its staff to wear many hats, billing can be time-consuming and complex. Worse yet, if the proper time and attention are not given to the billing process, you might end up losing out on a substantial amount of money.

Medical billing services can help alleviate that burden, but it might end up being more expensive. Often, for a percentage of your collections or a subscription fee, a medical billing service can take over your revenue cycle management and free up your staff to focus on other tasks. A good medical billing service will increase your collection rate, reduce rejections and denials, and even provide an analysis of your accounts receivable. You’ll typically be able to generate on-demand reports and view your day-to-day finances through the company’s software as well.

How to choose a medical billing service
When selecting a medical billing service, there are a few things to keep in mind. Of course, you’ll want to know what the costs of the service are, but you’ll also want to know exactly what you can expect from a billing partner.

“Your lifeblood as a medical practitioner resides with this function,” Montana said. “If medical billing isn’t working, not only are you not getting paid, but you won’t make payroll, and you can get in so much legal trouble with the insurance companies. You need to know what you’re getting.”

These are highly variable based on the size and specific focus of your practice. You’ll need to contact a sales representative for hard numbers, but some billing services’ websites offer a general estimate of what they charge. Companies most commonly charge a percentage of your monthly revenue as payment, often between 4 and 9 percent. It’s important to consider what the costs in time and money would be to keep billing in-house versus what the financial cost would be to outsource relative to the potential increase in revenue.

Tiny Satellites to Make Big Contributions to cloutet technology

Tiny satellites, some smaller than a shoe box, are currently orbiting around 200 miles above Earth, collecting data about our planet and the universe. It’s not just their small stature but also their accompanying smaller cost that sets them apart from the bigger commercial satellites that beam phone calls and GPS signals around the world, for instance. These SmallSats are poised to change the way we do science from space. Their cheaper price tag means we can launch more of them, allowing for constellations of simultaneous measurements from different viewing locations multiple times a day – a bounty of data which would be cost-prohibitive with traditional, larger platforms.

From proof of concept to science applications
When thinking about artificial satellites, we have to make a distinction between the spacecraft itself (often called the “satellite bus”) and the payload (usually a scientific instrument, cameras or active components with very specific functions). Typically, the size of a spacecraft determines how much it can carry and operate as a science payload. As technology improves, small spacecraft become more and more capable of supporting more and more sophisticated instruments.

These advanced nanosatellite payloads mean SmallSats have grown up and can now help increase our knowledge about Earth and the universe. This revolution is well underway; many governmental organizations, private companies and foundations are investing in the design of CubeSat buses and payloads that aim to answer specific science questions, covering a broad range of sciences including weather and climate on Earth, space weather and cosmic rays, planetary exploration and much more. They can also act as pathfinders for bigger and more expensive satellite missions that will address these questions.

Funded by NASA’s Earth science technology office, HARP will ride on the CubeSat spacecraft developed by Utah State University’s Space dynamics lab. Breaking the tradition of using consumer off-the-shelf parts for CubeSat payloads, the HARP team has taken a different approach. We’ve optimized our instrument with custom-designed and custom-fabricated parts specialized to perform the delicate multi-angle, multi-spectral polarization measurements required by HARP’s science objectives.

HARP is currently scheduled to the International Space Station. Shortly thereafter it will be released and become a fully autonomous, data-collecting satellite.

SmallSats – big science
HARP is designed to see how aerosols interact with the water droplets and ice particles that make up clouds. Aerosols and clouds are deeply connected in Earth’s atmosphere – it’s aerosol particles that seed cloud droplets and allow them to grow into clouds that eventually drop their precipitation.
This interdependence implies that modifying the amount and type of particles in the atmosphere, via air pollution, will affect the type, size and lifetime of clouds, as well as when precipitation begins. These processes will affect Earth’s global water cycle, Energy balance and climate.

For now, size still matters
But the nature of CubeSats still restricts the science they can do. Limitations in power, storage and, most importantly, ability to transmit the information back to Earth impede our ability to continuously run our HARP instrument within a CubeSat platform.

So as another part of our effort, we’ll be observing how HARP does as it makes its scientific observations. Here at UMBC we’ve created the Center for Earth and Space Studies to study how well small satellites do at answering science questions regarding Earth systems and space. This is where HARP’s raw data will be converted and interpreted. Beyond answering questions about cloud/aerosol interactions, the next goal is to determine how to best use SmallSats and other technologies for Earth and space science applications. Seeing what works and what doesn’t will help inform larger space missions and future operations.

The SmallSat revolution, boosted by popular access to space via CubeSats, is now rushing toward the next revolution. The next generation of nanosatellite payloads will advance the frontiers of science. They may never supersede the need for bigger and more powerful satellites, but NanoSats will continue to expand their own role in the ongoing race to explore Earth and the universe.

Healthcare Apps: UI-UX Factors to Enhance your Product

Healthcare industry is growing rapidly and various new technologies are emerging to cater the different target users of this industry in making their life easy. Every user in this industry has different expectations, and to meet their expectations, different systems are developed. In the recent past, most of these systems were web-based; however, with the increase in rate of mobile adoptability, mobile apps are being developed and are getting integrated with the new innovations such as Google Glass, Smart watches, Fitness Trackers, etc.

What do you think is the purpose of developing these advanced systems? A very simple answer is to make these services easily available. When we (as a Healthcare IT product engineering service provider) get a requirement for developing such a system, there are two scenarios:

  • Re-design the existing system with enhancements, or
  • Develop a brand new system

In both the scenarios, the main intention of developing the system is to provide a simple, clean interface with focused action items keeping in mind the different users/roles accessing the system.
First step involved in developing or enhancing any system is to define the user experience. It is to understand the flaws in existing system; evaluate them and then design a solution.

When we talk about different target users, we refer to payers, providers and patients. In brief, payers are the insurance companies who provide cashless or refund services. Providers are the healthcare facilitators like hospitals, doctors, etc. And patients are the people availing such services.

To understand the pain points of the users, User Interviews are conducted. In case of healthcare, Patients and Providers are the major users for whom such interviews can be conducted. Based on these inputs, Personas and Scenarios are created which help to explore the goals, needs, expectations of the user towards the new system and frustrations and pain points towards the old one. It also helps in bifurcating the roles and responsibilities of users.

The system designed should be user-centric such as if the healthcare app is designed by keeping the patient in mind, then everything must have the user experience for the patient. For example, if the application has a form to fetch patient’s details, that form should be well defined or well categorized so it is easy for the patient to understand and comfortable to complete the form. Similarly, considering patients age group, the app interface should be easy to find any information.

When the system is designed keeping provider in mind, it should consider facts like how a provider can be notified about his visits, appointments, surgeries, emergencies, etc.

Creating task flows, block diagrams and wireframes helps to give a structure to the tasks and define the simplicity of the screens. The navigation gets concrete and screen elements are finalized. All the flows are filtered through usability perspective and are structured in such a way that the task is completed with minimum steps. Finally, the branding, colors and typography is defined while creating the UI design. Interfaces are designed to fit various screens and devices.

So, UX plays an important role. Similarly, UI also play a significant role and below are some considerations while designing the mHealth app:

    • Use color for meaning. User might get confused by unnecessary colors. So, define a color system that makes it more meaningful than just a part of style.
    • Think of a very refined typography and hierarchy of information. Patients who are 45+ years should be able to read the information or take any action seamlessly. Therefore, your app should cater all age groups by providing a facility to change the font size as required.
    • For medical issues, users across the globe are seeking for remedies and solutions through their healthcare apps. In such scenarios, the UI should be personal and supportive, which would enable or rather motivate them to provide health data through the app.
    • Ascertain the RWD (responsive web design) are taken care of with elements that suit the app
    • Allow your app to integrate with other features of the phone such as the front camera can be used by the doctor to access the patient. This will also help in expanding the scope of your app.
    • A voice recognition tool can be used by medical staff to input patient data so as to increase the level of interaction with the patients

We see that UI/UX plays a very vital role in developing a system that is more user-centric, provides better usability of the defined functions and tasks to be performed and offers a good interactive and informative platform for different user base.
