Hi Markus, people, >By their very nature, these virii attach themselves to private emails >without the user's knoweledge, so the text therein would be whatever >the sender had written to you. Incorrect. The virus decribed is ExploreZip. Other virii have used this same behaviour of *not* attaching to user's emails but generating & sending their own generic emails. You mentioned CERT as an authority, but do not appear to have checked them for info. They issued an advisory for this virus coded CA-99-06-explorezip. www.cert.org >On the other hand, there are lots of fake virus alerts going round. Talk about fake alerts when a fake one comes up. >But personally, I'd like to see the name of the attchment before I >begin to worry about this one. Virus variants rapidly appear using altered names etc. Non-specific text etc is probably a more reliable indicator of dubious origin. Never open an extension unless it has been discussed or accompanied by specific personal communication from the sender. Cheers, Thomas
