Dick Montage Posted May 15, 2007 Share Posted May 15, 2007 Wasn't there a virus a long while ago that did that? Link to comment Share on other sites More sharing options...
mshepp Posted May 15, 2007 Author Share Posted May 15, 2007 I hope not. I cant find any info on it at all, anywhere. This thread ties in with another one i posted about my pc not booting or reseting. https://www.neowin.net/forum/index.php?showtopic=560352 I dont really know whether its a hardware issue or something to do with the software.

This thread ties in with another one i posted about my pc not booting or reseting. https://www.neowin.net/forum/index.php?showtopic=560352I dont really know whether its a hardware issue or something to do with the software. Hi, first post here... just been looking into the same issue on a friends laptop - vista premium, all updates, ie 7 and firefox... read your post earlier - this laptop was shutting vista down automatically on a few sites and whenever a download was attempted. I created a new account which creates a new profile and the problem does not exist. I probably won't look further oz I have already spent a couple of hours on things like java and flash updates, browser test sites etc. so will just create a new account and transfer data... hope this helps... Many blessings... Chris ) John 3:17 Link to comment Share on other sites More sharing options...
Christian Chris Posted February 4, 2008 Share Posted February 4, 2008 Update to last post. Before I gave up on the profile I added AVG and it found a worm i-worm.vb-tc I think. AVG deleted one instance which then allowed the original profile to download file from the internet successfully. I then ran a full a scan and it found several other instances which were dealt with. Laptop is fine now. Chris :) Link to comment Share on other sites More sharing options...
