If you have XP, vista32bit or Win2k, you could enable a boot time scan. Right click the avast icon, select Start avast! Antivirus, a memory scan will take place followed by the opening of the Simple User Interface, Menu, ‘Schedule boot-time scan…’ Or see http://www.digitalred.com/avast-boot-time.php.
How to restore Safe Boot.
The malware may have deleted the SafeBoot registry keys.
Here are some options to restore them:

If you haven’t already got this software (freeware), download, install, update and run it, preferably in safe mode and report the findings (it should product a log file).

Welcome to the forums, Dibiase. 
Please follow David’s advice above and let us know the results.

they didnt work 
o forget it… no one knows my problem unless you see it(or have/had it)
Which didn’t work ?
Are you talking of the Didier Stevens links, or SAS or MBAM and can you expand a little on ‘they didn’t work,’ that gives us nothing to work with ?
I can’t believe that you have downloaded all of the anti-rootkit tools and run them in the 15 minutes or so since I posted them ?
Well, Dibiase … we do not give up so easily but if you do, then we can not help you.
