What is the best free antivirus software?

I wonder which of the following is the best antivirus software Free. What is the best score in the search for a destruction of the virus? What else to protect my computer? Or any another opinion. AVG Avast Home Edition Avira personl

Well for starters, let's cover versions of antivirus freeware available and covered by that often fall short. The free version of AVG (as opposed to the current commercial version) covers the basic needs of security, with simple and straightforward interface graphical user interface (GUI) for almost anyone can use. However, it has a relatively low rate of detection of the virus (around 81%, but is keeping track?) and a false positive rate that is higher than most, which means that a virus is detected when there is none. The copy does not include adware free or spyware removal and support for the product is limited. While it is safe-mode support, a nice profit for a Free AV has some rootkit detection, no records of exploration, no firewall, and has recently acquired a resource of greater presence with the addition of email scanners, bar browser tool, and a link scanner. With the irregular protection and securing the necessary resources, AVG is becoming less useful as the "light" alternative to Symantec or other and generally do an effective job in protecting a system correctly. Avast! Home Edition is another free security suite that protects against virus, spyware and rootkits, as well as scanning of P2P and instant messaging. Includes WebShield that scans all HTTP traffic and a firewall that uses light signature-based detection to find known viruses and worms. It also has 64-bit compatibility, so it is a good choice for some of the new systems the market. While all these features give an adequate level of protection for the price, the strongest features of resources tend to Avast! a little slow to start the virus scan. In general, this is one of the best free security applications. While there are several popular software applications free antivirus out there all tend to have the same defects: weak or no firewall, a high number of false positives (to scare users into purchasing the "best" edition suspect), protection from rootkits and Trojans little or nothing, no real-time analysis, not "self-defense" of the application (what the already vulnerable AV attacks), and the general incompatibility. While these tend to be general problems that normally arise from implementing the goal of trying to be "light" and "simple", while unfortunately tends to sacrifice their own safety. As far as the paid versions, which tend to solve all the problems mentioned above, but the curse of the popular treat. Symantec and McAfee are the two main examples, the popularity of these has become so great that developers often malware will not release the code in the "nature" (the public) until you can pass as clean. This allows the virus to evade their own forms popular protection and potentially infect more computers for longer. In my opinion the best overall security suite is Kaspersky, which has a footprint lighter than competing products has improved safety overall free versions, and is a reasonable price for an annual subscription.
