After two years, Netsky-P is still worst virus
The email worm was ranked number one on the malicious software chart despite fixes having been available for a couple of years
Netsky-P led the top 10 chart for malicious software threats in August, retaining its rank despite the availability of fixes for more than two years.
During August, Netsky-P accounted for 19.9 percent of all malicious software incidents reported, according to a report released on Friday by security researcher Sophos. Netsky-P, which remains the most widely spread of the email worms, was ranked the worst virus of 2004.
Just one in 278 emails was infected during the month, a significant decrease compared with August 2005 when one in every 50 emails circulating was viral, according to Sophos.
Sophos identified a total of 1,998 new threats in August 2006, with Trojan horses accounting for 71.8 percent of those threats.
