Does an Antivirus Prevent All Viruses from Attacking My Computer?
Thanks to antivirus software, you can prevent most of the viruses from playing havoc on your computer. Well, why this 'most' tag here?

Here is the suggestion by me of 5 best antivirus ever!
AVG Free provides protection against the various nasties floating around the internet. Like many of the options in the Hive Five, AVG provides freeware (with limitations) and commercial versions of their software, but most users find AVG Free is all they need—though many users prefer versions prior to the most recent 8.0 release. 
NOD32 is best known for its speed and small system footprint, but users also swear by NOD32 as a comprehensive and bulletproof solution. At $40/year for a home license, it's not free, but NOD32 die-hards claim the pricetag is well worth it.
Available in both freeware (Home) and shareware (Professional) flavors, Avast Antivirus is the happy home of many an AVG-switcher. Avast is slightly heavier on system resources, but users argue its excellent protection more than makes up for the increased footprint. The freeware version will cost you an email address to get a free registration code from their website.
According to many of its users, Avira is the go-to freeware app for detecting viruses and other malware that other antivirus apps miss. Like several of its peers, Avira is available in both freeware (Personal) and shareware (Premium) versions, and most people find the freeware alternative plenty to suit their needs. One downside to Avira on install is pop-up ads enabled by default (adware, anyone?), but you can disable the ads with a couple of clicks.
Fans of shareware antivirus app Kaspersky point out its consistently strong ratings in malware protection as well worth the $60 license. Kaspersky also boasts an extremely quick response time to new viruses, earning it a special place in the hearts and system trays of its users.
