Lately, I have been experiencing the strange windows behavior. Ocassionally, on Windows XP Pro startup, when I get to choose the User Account (in my case LeDeni - which is actually administrator) it asks me for the password which I never actually had. Whichever password I type (or leave the field blank) it says that the domain is not accessible. But I'm not using logon via domain in the first place. If I try to login with Administrator account, it appears as it was trying to log in but it takes forever then I am returned to login again. Sometimes restarting the computer solves the problem, but sometimes I have to restore through System Restore from Safe mode (Safe mode logs in normally). Is this connected with some keyloggers or corrupt Windows files or it has something to do with malware etc.?
