Hi. Recently I am quite certain I got nailed with a virus or two. My task manager has an ever growing collection of "wuaclt.exe" files in it whenever I run my computer. I have seen on many sites that this is a virus, but I can't find any one that tells me how to remove this file to stop the obvious re-infection/growth. I need advice to delete it. Spybot, Adaware don't even recognize it. Hijack this finds it but can't remove it or help me find it except when it's running. I also had the "libsys32.exe" running which also came up as a potential virus. I think I finally got rid of it, except for one file which I renamed and it seems to have become harmless for now. The upshot of these problems is that when I start my computer, Explorer starts as normal, then shuts down. A second or two later, it restarts and then stays open for a limited length of time (less than 2 minutes, but usually more than 10 seconds). I don't know where and how to fix this problem. I've never seen this before and have been running my software through the task manager since it started. But now, when I disconnect from the internet (done by ending the process for the "pctspk.exe"), the task manager locks up and I have to reboot by the power button. Any ideas on how to fix this issue, or free software that isn't incredibly crippled to uselessness to fix registry errors would be greatly appreciated.
