People often ask what the most popular and best antivirus Especially for those who do not know I decided to do something like a small experiment in the end I know some of the most popular anti-virus is the most effective! To experiment, I decided to choose the three most popular anti-virus. This Kaspersky Anti-Virus (kaspersky), AVAST 4.8 Pro and anti-virus software NOD32! And when I have all three of these antivirus with license keys do I begin my experiment. March 1, 2009 - I began to conduct this experiment. I reinstall the operating system has put all the utilities and drivers, and of course the first set, which was on the list, antivirus. It was Kaspersky Anti-Virus. He established successful and without any problems and immediately updated. Resources, he demanded not much. I turned to a hacker friend and asked him to send a pair of attacks on my computer viruses. Here and now is over a good story. Of the 100 attacks Casper rescued only 70%, which means that 30 files on my computer became infected and the antivirus did not even noticed! I asked the same hacker that he gave me a link to a virus file that I downloaded that file! You will not believe, but the antivirus does not even hint at the expense of the harmfulness of this file. Kaspersky Anti-Virus, I enjoyed 5 days and during those 5 days, I put him to assess 3. March 7, 2009 - I started the second phase of his experiment. As a first step, I reinstalled Windu, and then put it on the PC anti-virus, which is second on the list. This antiviruska Avast 4.8 Pro. Established it as successful as the previous one and as quickly updated. The actions were the same. Ask a friend to send 100 attacks on my computer worms. The result was a very radosnym. Avast repulsed 94 attacks of 100. Not all 100 of course, but better than the previous one. Then I wanted to download one infected file, which I so easily gave Upload Kaspersky. The result was very good, AVAST immediately informed that the file is infected with a virus and does not allow me to download the infected file. Resources requires not much. Used this antivirus a week and put him to assess the 4 +. March 15, 2009 - the third step of the experiment. Put antivirus NOD32, which is third on the list. As in the previous steps, I reinstalled the operating system and installed antivirus nod32. Established NOD32 as well as two previous ie Ok! Actions Anti-Virus scan were still the same as in the previous stages. Of the 100 attacks he hit only 83, that is not a positive result. And in the case of downloading an infected file, the antivirus did the same as Kaspersky Anti-Virus! Resources requires more than all the previous anti-virus software. NOD32 Anti-Virus, I used 4 days and put him to evaluate 3 +. He remembered that someone asked about antivirus Dr. WEB. His I, too, once tested. The actions of this anti-virus were the same as that of the previous anti-virus applications. Of the 100 attacks that antivirus repulsed the same number of attacks and antivirus Nod32. With those infected objects Doctor Web, behaved well, he does not allow me to download the file because that file was infected with the virus. System resources requires not much. During the use of this antivirus I can put him evaluated 4 -. (This antivirus I tested before my experiment).
