Need help fixing auto logoff(virus?) or uninstalling Windows 7

[hawksking]

Hi,
Last night I downloaded a file which contained a virus(the source told me it was a false positive), that time it was all good. This morning I went on the computer and from multi boot I choose Windows 7(other was Vista) and when it prompted me to account screen I chose my account and logged in. Suddenly everything shutted down on start up and logged off and went back to the account selection screen. It is happening everytime Im logging on to Windows 7.
I ran a scan in Microsoft Security Essentials and there was no virus/malware found.
So, I want to run Windows 7 and fix this problem else I want to delete Windows 7 and install a new one with the CD I was given by Acer for Windows 7.

Thanks

First acer may not have given you a win 7 dvd but rather a restore dvd. check before you do anything

second download malwarebytes and run in safe mode.

Let us know the results
