I'm puzzled as to what happened.\n\nMy PC is on 24/7, connected to the internet. It uploads weather data\nevery 15 minutes and downloads a few minor things at set times\n(GetRight). I run AVG that scans every night starting at 1am, which\ntakes about 3 to 4 hours to scan 3 disks.\n\nNow, this morning the computer had completely shut down with just the\npower light on. What puzzles me is had it 'crashed', say from a local\npower cut/blip then I would have expected some message recovering from\na system error or something. But the only application, when starting\nup, that asked if I wanted to use previous tabs was Firefox.\n\nNothing is obvious in the system event log, but the AVG Scan had not\ncompleted and this was stated. There were two virus entries moved to\nthe virus vault:\n\n"Object name";"C:\Documents and Settings\LocalService\Cookies\n\email@example.com:\adtech.de.a9245469"\n"Object name";"C:\Documents and Settings\LocalService\Cookies\n\firstname.lastname@example.org"\n\nBut I don't think these are the cause.\n\nGoing by when my weather uploads stopped this happened just after\n03:00 BST.\n\nAny thoughts?\n\nMany thanks\n\nKeith (Southend)\n[URL]http://www.southendweather.net[/URL]\n"Weather Home & Abroad"
