Recently I have been getting a warning pop-up on my computer mentioning a bloodhound virus. Anyone know what this is?

Bloodhound is a Visual Basic worm that spreads via e-mail attachments through Outlook and peer-to-peer file sharing networks. The subject line will refer to "freedom of expression" or indicate that the body/attachment contains a legal notice of some sort. The message will have various attachment names and extensions. Bloodhound/Fili infects all Windows versions except 3.x, but not UNIX/Linux or Macintosh systems. Upon activation the initial version of this worm will block some anti-virus processes (not Norton/Symantec) and compromise other security applications.

If you use Norton AV check this out also:

Which AV system are you running?

Be sure to do a full, intensive virus scan on your computer and see what happens and let us know...
