How much malicious code is really out there?

The Internet is evolving incredibly fast. We are always warning users about cyber-threats, but many users do not take this seriously. One problem is new users who don’t have much experience – there are more and more every day, and they don’t think viruses are a real problem. Our survey on the Russian version of Viruslist.com told us that only 25% of users update their anti virus databases every day – this gives lots of opportunity for new infections!

This morning a friend phoned me saying there is ‘something wrong’ with his computer. He installed a dedicated Internet line a week and a half ago, and at the same time reinstalled his operating system. He didn’t believe his computer could become infected in this short time.

It’s no surprise that the computer was infected – what is maybe surprising is in just a week and a half my friend managed to pick up 78 (!) malicious programs:

Here is a summary of the results:

Trojan – 36
Trojan-Clicker – 2
Trojan-Downloader – 11
AdWare – 26
RiskWare – 3
