The report, compiled from Sophos's global network of monitoring stations, reveals that Netsky-P, which recently celebrated its second birthday, has returned to the top of the virus chart, replacing Zafi-B, which Sophos first protected against 22 months ago. However as a proportion of all malware, email viruses and worms continue to decline - 86% of the threats reported to Sophos during April were Trojan horses, used by hackers to download malicious code, spy on users, steal information or
gain unauthorised access to computers.
The top ten viruses in April 2006 were as follows:
1 W32/Netsky-P
2 W32/Zafi-B
3 W32/Nyxem-D
4 W32/MyDoom-AJ
5 W32/Netsky-D
6 W32/Mytob-FO
7 W32/Mytob-C
8 W32/Mytob-Z
9 W32/Dolebot-A
10 W32/Mytob-AS
