I have Windows XP professional w/SP3. It's been run hard every day since 2006 or so. I suspect it has a deeply ingrained form of malware or virus or some deleted file or other horrible thing. Recently when I boot up it takes over 10 minutes to load and then the welcome chime never happens and the icons and taskbar will not load, all I see is my background. I hit ctrl+alt+del and there are only 21 processes going and explorer.exe IS actually one of them. In the past I've been able to boot up in safemode and do a system restore to the day before and go on my merry way. Not so this morning, I tried a couple different system restore points and they wouldn't go through. I had contacted microsoft and they suggested it was a corrupt user profile. We went through the process of creating a new user profile and tried to copy the files over but got an error message saying that some of them could not be accessed and the dump was stopped. So I deleted the attempted new user was told to reinstall windows by microsoft and have come here instead. I am not computer savvy, I know how to do what I'm told and click the scan button on Bitdefender and Malwarebytes. Any help would be greatly appreciated.
