So lately my computer has been acting kind of funny as of late. A few weeks ago I was having some problems with my video card where the system kept locking up randomly on me. I seemed to get that fixed after taking the card out reseating it and also turning off my screen saver since the comptuer was only locking up with the screen saver was coming on. After that the computer was working find. And still seems to be but it is rebooting in the middle of the night. I know that because there are certain windows that I will leave open when leaving the computer for the night that won't be open in the morning. Also my Nic will only show as being connected for a few hours. This morning I noticed that the time that the Internet showed as being connected for was about the time that AVG was schedule to run during the night. So I go and check the logs. last completed scan was on 3/30 and all the other scans up there was a virus for quite some time. I looked at the logs and the file that says it was infect I found a while back and had deleted. Although it is still showing up in the same directory in the scans. Even though in all the logs when it says it finds it, it also cleans it. Yet it is still there in the scan the next night. Well since I haven't had a complete scan for a while I decided to run another scan. Comuputer reboots. Tried going to antivirus.com and running the only scand there but it keeps stopping when it says it is trying to update the definitions on my system. Tried to restart several times and it gets a little farther but never actually makes it all the way through. Finall start on running Panda's online scan and it is still running with out any problem so far. Although it has seemed to find 12 spywares on there that spybot, adaware, and Windows Defender have never found. Could this be just a corruption in windows possibly caused from all the reboots and freezes I have been suffering, or does it sound like I have some sot of virus running back that that is now not allowing my AVG to be able to complete a scan.
