The new Sober worm variant is now spreading in 40 countries and accounts for 79.29 percent of all viruses monitored by Sophos monitoring stations around the globe. The anti-virus company calls the new Sober the biggest virus outbreak of the year.
The security firm says Sober-N now accounts for 4.5 percent of all e-mail sent across the internet. The worm causes a lot of problems because it tricks people into believing they have won a free ticket to the World Cup 2006 tournament in Germany.
"One in every 22 emails sent across the internet is currently infected by the Sober-N worm - making this one of the biggest virus outbreaks of the year," said Graham Cluley, senior technology consultant for Sophos.
"All internet users must secure their systems with up-to-date anti-virus software and ensure that they never open unsolicited email attachments. No-one should be fooled into thinking that email viruses are a thing of the past."
