The antivirus software provides an essential layer of protection for a multitude of viruses, Trojans, worms, spyware, adware, dialers, keyloggers and rootkits infections. Traditional antivirus programs is the detection of viruses and spyware spyware detected, but today the line between viruses and spyware removers is unclear. Most current antivirus detection rates at least reasonably well in all forms of malware.

Malware includes viruses, trojans, worms, spyware, adware, dialers, keyloggers and rootkits threats perform malicious actions on a computer. With the huge increase in malicious software, antivirus software can not stop showing it all. But using more than one antivirus in real time using more system resources can cause conflicts and even reduce protection. So I recommend you choose one program real-time virus protection. Instead, you can increase your protection by using security software.

I looked at several free antivirus programs that are essential to protect your computer against virus threats and other forms of malware.

Discussion of best Antivirus
AVG Anti-Virus Free Edition is a good choice for a free antivirus. Although this venerable antivirus had some weak results in the detection in the recent past, now offers a high level of protection. This is probably due to the inclusion of a behavior blocker, which is full of "protection of the identity" of protection. This provides an extra layer of protection that are very important, however, if a similar level of protection can be achieved by using one of the free antivirus above, along with a different behavior blocker. Unfortunately AVG free has increased considerably in size, has a very slow scanning speed, as well as advertisements (but can be disabled), that is why many people have decided to remove AVG antivirus with the AVG removal tool and try other more effective antivirus applications.
