I ran across this post yesterday and decided that it’s definitely worth linking to. People ask me “Which antivirus is the best?” And “What do you think about <insert antivirus name>?” At some point in my answer, I try to remind them that the virus writers are checking their work against those same antivirus programs that you are using.
This means, like a software developer, they won’t release their work until it’s of a high “quality”. In the case of a software developer, it’s how bug-free the program is. In the case of a virus creator, it’s how FEW antivirus programs catch their work.
The problem is, that sites like the ones listed in this article (not VirusTotal or Jotti) aren’t helping any. Where VirusTotal and Jotti will submit the file to the antivirus companies, the other sites absolutely guarantee that no antivirus company will see the file (from them).
Are they legal? I’m not entirely sure. Should they be legal? Yes. As much as I hate saying that, they should. It would be nice if they were regulated in a fashion that required them to submit the files, but they should be legal (because in order to make them illegal, you also hit the “good” sites).
Take a look at this article. It will open your eyes a little more about how effective your antivirus is, and why.
Have a great day:)
