Avast was performing its scan and it detected a Win32:Malware-gen worm. I’ve tried to move it to the virus chest, deleting it, and repairing it. To no avail, none of them worked as I ran the scan after each of those processes and Avast still alerts me that it is still there. I’ve also attempted to restore to previous update settings and used the online Avast cleaner and none of them worked.
Try a scan with these
MBAM http://filehippo.com/download_malwarebytes_anti_malware/
update, run quick scan and click “remove selected” to quarantine anything found, and restart
SAS http://filehippo.com/download_superantispyware/
Are cookies really spyware and are they dangerous?

come back and post scan logs here
Why couldn’t it deal with it, e.g. what errors were displayed (file in use, etc.) ?
If you have XP, vista or Win2k (all 32bit), 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. Don’t opt for deletion (you have no options left), always send to the chest and investigate.
Look in the C:\Program Files\Alwil Software\Avast4\DATA\report\aswBoot.txt file, check this file using notepad and copy and past the info on the detection.
