Hi guys
When I first open a browser window (IE6) I have no probs, my default page is set to Google and all is fine. However, usually within 5 or 10 mins any other browsers I open or if I click 'Back' on my initial browser window I get "Page Cannot Be Displayed". there is no way out of it a present except to reboot and then I'm ok again for another 5 or 10 mins. It's driving me crazy ! I have Norton AntiVirus Corporate Edition (which has always been kept up to date), I have 'Tiny Personal Firewall' (with which I've had no probs) and I have recently scanned using 'Spyware Doctor' (which founds loads of Trojans and other stuff which have supposedly been fixed and/or quarantined). I'm guessing I have another Trojan 'floating around' somewhere but what do I do ?
Here's my HijackThis log below ……. help would be greatly appreciated.
