passwords keep getting changed...

[pkerpure9]

I have a problem with my passwords. My hotmail,msn, gmail and Facebook passwords get changed out of nowhere. I just got a new computer maybe a month ago. I have not downloaded anything on to it. Only websites I use are trusted websites, mostly tsn, my school server, and sythe. I am pretty sure I do not have a virus..anyone know what can be going wrong?

It's nearly impossible for your passwords to change if no one else knows them. 99.9999% sure that someone else may know your security questions to your emails. I'd suggest you change security questions and passwords then see what happens.

Sounds to me like you have a Keylogger.
If I were you, I would use my System Restore feature to the earliest point you can remember before your passwords were getting changed.
