There are many anti-virus programs that you can download or purchase at BestBuy, Staples, Office Depot, Amazon, Ebay or anywhere else you shop. As with cars or any other personal property there is always a lively debate about which is the best.  And, that is always a matter of opinion, right? Nevertheless, here are five free antivirus programs that are arguably just as good or better than the paid stuff.
 
Avast is a popular anti-virus program designed for Microsoft Windows, Mac and Linux computer users.  It is available in 41 different languages and has won awards for 100% detection of viruses.  This software specializes in blocking viruses and spyware and has the ability to secure your personal information and all of your stored data as well.
 
AVG is highly popular software available to download onto your computer. Many people use AVG not only on their PC’s and laptops but also on their mobile phones.  It detects malware, viruses and other infections and attempts to stop them before they populate on your machine or device. An added feature of AVG is that it also claims to keep your banking and shopping records safe and untraceable so no one can get access to your credit card information or banking logins.
 
Avira is a nationally known and family owned business that specializes in anti-virus software and protecting your computer with its services.  They have over 100 million customers and are ranked at number six on the list of the largest anti-virus vendors worldwide.  The free system runs background checks on each file stored in your computer and updates itself automatically when the system has new updates.
 
Comodo is an anti-virus protection software that includes anti-malware protection, personal firewall, sandbox and intrusion prevention.  It can be installed on Microsoft computers and Linux systems as well.
 
Microsoft Security Essentials is perhaps the easiest and best free antivirus solution out there.  It is from Microsoft itself.  Unlike the old, pared-down “Defender” antivirus program this is a fully functional antivirus software suite that provides “real time shields.”  It protects against computer viruses, spyware, Trojan horses and even rootkits. It can be run on Windows XP, Windows Vista and Windows 7.  It is light and does not slow down your computer by draining system resources like some of the other products on this list.  This is my personal favorite as it is light, effective, and does not try to get users to upgrade to the pro-paid version every time they look up.
 

Does your computer ‘hourglass” constantly?  Do error messages frequently pop up on your screen?  Do webpages load slowly? Some of this is normal but if it occurs regularly your computer might need a tune-up. Your car, for instance, reliably transports you to and from work, to get your food, to the doctor when you are sick, and to your relatives when you want to visit. Important stuff! But, it only does these things if you tune it regularly; if you change the oil, check the battery change the spark plugs, brakes etc. Why would a computer be different?  It’s not!

It only remains a useful tool for exchanging email, communicating, researching topics, and creating and storing your pictures and other important files, if you give it the proper care and maintenance that you would give any other expensive tools or possessions.  Do you know how to keep your computer in tune? How much did you pay for your computer? How about the software? What value do you place on the files saved on its hard drive? The figure is probably in the thousands, so learning how to keep your desktop computer or laptop in tune is important. Here are my suggestions on how to do it.

Uninstall Unnecessary Software

Most of the computers that come into my shop are full of software that has been installed, accidentally. Updates, honest utilities, and even purchased software often comes with add-ons, tool-bars and additional software bundled that is unnecessary and can wind up bogging down your computer. Go to start >Control Panel>Programs>Add/Remove and review the software on your computer. “Google” or “Bing” any software that is not from Microsoft or another known source and read about it. If you determine it is an accidental install — uninstall it. Especially look for toolbars which tend to be intrusive , pervasive, and “pre-viral.” Just make sure you don’t uninstall any of your system software that is necessary for your computer to operate. Again, if you have any questions about the software, Google it or Bing it and see what it is responsible for before you uninstall it.

Delete Temporary Files and Fix your Registry

Over time your computer will build up a long list of temporary files associated with your web browsers and other software on your computer. They accumulate as a result of programs shutting down incorrectly and forgetting where they left their temporary files, browser hiccups, tracking information kept by websites to monitor your activity and a for a myriad of other reasons. To clean these fragments up, download the free utility called CCleaner from Piriform to delete temporary files. The website is http://www.piriform.com/ccleaner and the free version is all you need. It’s not necessary to upgrade, in my opinion. Also, use the registry repair tool to fix your registry which also becomes fragmented over time from normal use.

Run Virus Removal Utilities Often

Malware, Trojans, Spyware, and Viruses often build up on computers over time. Computer viruses are like human viruses. You probably have some living on your computer at this moment. Some never cause much problem and some can stop your computer in its tracks. But, usually I see a slow accumulation of infections over time that eventually render a computer nearly useless. This can be prevented by running virus removal utilities on a regular basis. There are plenty of these programs that you can run on a weekly or monthly basis to remove small viruses that might have slipped in. A good one for consumer use is Malwarebytes. The free version is available at http://www.malwarebytes.org. Just make sure to stick with the free version –don’t do a free trail of the professional version by accident (remember I was just talking about accidental downloads). Note: Many viruses require professional virus removal to be removed completely. If your computer is redirecting you to websites that you didn’t command it to, playing sounds randomly, or running extremely slow you might have serious infections and you should call a local computer repair shop immediately.

Eliminate Aftermarket Browsers and Reset Internet Explorer

Browser health is an important aspect of keeping a computer in a well-tuned state. In fact, it’s one of the most important components. Aftermarket browsers such as Mozilla Firefox and Google Chrome can be great. Sometimes they provide functionality and “bells and whistles” one can’t get with ‘plain ole’ Internet Explorer. But often over time these browsers can harbor and hide a myriad of infections which can degrade your computer internet browsing experience. For a minor tune up learn how to reset IE, Google Chrome and Mozilla Firefox. For a major tune up you can eliminate Google Chrome and Mozilla Firefox – then reset Internet Explorer. You can reinstall aftermarket browsers later.

Make Sure you Only Have One Antivirus Suite

The software conflict that causes the biggest resource drain on computers is double anti-virus installations. Often this happens because when a free trial ends, or new antivirus software is purchased, users fail to uninstall the old antivirus software before installing the new. Antivirus software is one of the most resource-intensive applications you will run on your computer. It runs all the time attempting to scan and detect viruses in “real time,” which translates into a big drain on system resources. Therefore, if two antivirus suites are installed on a single machine, it can become practically unusable. Make sure to look in the add/remove section of the control panel and completely uninstall any old anti-virus installations before installing a new one.

Tuning up a computer gets rid of all of the excess garbage that has built up on your machine over time. So, try your own computer tune-up. “Google” any questions you have and read what others are saying about it. Next time you’re slamming your keyboard in frustration, think twice about buying a new computer or taking it to the repair shop. It may just need a good tune-up, and now you know how to do it yourself!

A Computer virus is software embedded with a particular code intended to hack a system or network so as to steal, corrupt, or control against the will of the user. The origin of viruses can be traced back to the advent of the computer itself. Although you might not be aware of it you probably have viruses on your computer as you read this. Here are some simple tips to help keep malicious software away and keep your computer running the way it is supposed to.
 
Ensure Your Firewall Is On
 
Firewalls prevent unwanted programs from getting access to your computer from outside. According to Wikipedia “a firewall is a software or hardware-based network security system that controls the incoming and outgoing network traffic by analyzing the data packets and determining whether they should be allowed through or not, based on a rule set.” A firewall establishes a barrier between a trusted, secure internal network and another network that is not assumed to be secure and trusted. If you are using Windows it is best to turn Windows Firewall on. It’s a simple settings issue in the control panel.
 
Use Effective Antivirus Software
 
There is preventative medicine for these virus infections in the form of anti-virus software – which is abundantly available. There are both paid and free versions of them which you can either buy or download freely from the internet. The key here is that the software has “real time protection.” which should prevent many viruses from populating on your machine and keep you fairly protected. Notice that I have underlined “many” and “fairly” in the previous sentence. A variety of viruses can skirt anti-virus software with relative ease; therefore, it is imperative that computer users monitor their behavior – adopting and developing good web browsing and “computer hygene habits” in order to ensure immunity from viral threats.
 
Use An Antimalware Utility Regularly
 
While antivirus software seeks to prevent viruses “on the front end” or before they populate on a computer. Anti-malware utilities remove virus infections after a machine is infected. There are plenty of anti-malware programs that you can run on a weekly basis to remove small viruses that might have slipped in. Two that I use include Malwarebytes and Spybot Search and Destroy. Note: Many viruses require professional virus removal to be removed completely.
 
Run Updates
 
It is quite obvious that viruses like any other programs continually seek new ways to hack systems and hence the resistance of the operating system needs to be reviewed and updated regularly. Manufacturers of such operating system meticulously do that; therefore, you should download and install the latest patches and updates released by the operating system manufacturer.
 
Learn Good Web Browsing Habits and Computer Hygiene
 
Last and perhaps most important: strive to improve web browsing habits and PC maintenance and hygiene regimens. A gun has a safety and roadways have guardrails but they provide limited protection. Ultimately, we are responsible for our own computer health. A few things you can do to improve web browsing habits are to avoid websites with numerous pop-ups related to them. Don’t open suspicious emails, and be wary about free so-called “useful utilities” (media players, picture viewers, Facebook enhancers, “game helpers”, coupon printers, etc.) Furthermore, you should read-up on, and implement a program to keep your computer clean and “in tune.” CCleaner from Piriform is a good free system cleaner that should be used on a weekly basis. Learn to do things such as keep your browsers free of extra toolbars and add-ons, keep temporary files deleted, and keep files and folders organized on your machine so you can recognize any changes, etc. For more information on how to keep your computer “in tune” and virus free visit my website and blog here.
