jamie, prolly u r receiving e-mails with virus thru outlook.
I have some machines with that version of virusscan (but with a fresh .dat) and sometimes it happens, but not when on outlook (i dont use that crap - i advise you to stop using outlook too)
When the users (including myself) are browsing thru internet, from time to time virusscan pops up those kind of alert. If you press "delete/clear" for the action, it said "cleaned/deleted" but after a sec it pops up again the same alert. you cant do anything on the second one, because virus is already deleted. But viruscan wont give up to alert you. The only choice to stop that alert is press "stop".
According to Vendor, it happens due to diferent instances of antivirus engines trap the same virus.
One instance, attached to file processing (system scan), trap first virus and alert you. While you are instructing a/v to destroy the virus, a sencond instace ("html" processing) detect it again when checking html just d/l. but the pop up wont appear until you answer the first one.
So when you answered the first one, a second pop up will appear, but its an old one.
IF IS THE SAME ONE <------ be sure of that -- just press STOP.
It is annoying, but it is for your good (words from Network Associates :P )
I think the 7.0 engine is smarter and consolidate all alerts from diferent instances before ask you to choose an action.
So my guess in outlook is: you are receiving tons of virus thru e-mail. That annoying feature of outlook (preview pane) trigger again and again and again the html processing of the message. A temp file is created to process that. Virus is presented to A/V and A/V react to it.
