The storm worm trojan spam outbreak that started last Thursday (which we reported on here) pushed global virus levels to 60 times the normal daily average. Users should continue to be on the lookout for "love" and "worm alert" related subject lines and emails with password protected zip files.
Given the fact that the storm worm senders have relied on subject lines citing real world news events in the past, it might also be prudent to be on the lookout for emails with subject lines referring to the terrible tradgedy at Virginia Tech University today.
