Did not detect any virus. There is a discussion going on in the XP forum about the same. Sorry but I thought there was not going to be any more replies. Another fellow has the same little pop up box as me. I checked event viewer at the exact same time it happened but nothing was shown.
I have a window that pops up intermittent in the task bar. It is about the size of the OE envelope. It is a rectangle with the top and bottom borders in blue. It pops up for no reason but is gone in about 2 seconds.
I have of course scanned this machine with AVG, Spybot and AdAware, nothing found. Checked running programs but nothing unusual as far as I can tell. I have yet to use house call, (just thought of it) so I'm off to that site. Meanwhile if it sounds famaliar I'd appreciate any advice.
