Hi all, For the last couple of days, I've noticed that my CPU was running at 100% and the *supposed* culprit was a known Microsoft system tool called dllhost.exe. The high cpu rate only occurred when I was online and while an automatic Windows update was taking place. I thought everything was normal...but just to be sure, I began reading the forums. Long story short, everything seemed to point to a normal process (Please See Link: http://www.answersthatwork.com/Tasklist_pages/tasklist_d.htm ) but I just couldn't believe that any normal process could use that many resources for that long with no end in sight. I went to sarc.com and learned about the Welchia virus, downloaded their tool and, lo-and-behold, found I was infected! I deleted the virus but now I'm a little concerned. 1. I have recently purchased my computer and it is still under warranty. My question is, could that high rate of cpu usage over a span of a few days have caused any hardware damage? (i.e., heat damage due to the VERY high temp associated with cpu use) 2. Normally, my cpu usage ranged in the 1-3% range. But now after removing the virus, cpu usage is in the 3-7% range. I'm concerned some sort of "residual" processes associated with the virus are still around. Can this be true? 3. I really hate patching stuff like this in Windows (things never seem to run right afterwards). Is it recommended that I do a fresh install of Windows? Thank you very much for any help you can provide! SPECS: 2.2 Ghz 512 Mb RAM Windows XP PRO
