I've noticed lately my computer at home has been running a little slow. I'm running windows 7. I did the 8 step process. Can't seem to find any viruses. GMER will not run for some reason. Says C:\system32\config\system: The system cannot find the file specified. When I went to look for this file myself I noticed it has a padlock on it. So im assuming that file is locked. I couldn't figure out how to unlock it. I tried running in administrator to no avail. I'll post what I have so far though. Thanks for any help offered.
