Don’t let your email listed here or spambots will caught it and fill your mailbox with spam…
Also, what happens exactly with avast installation, what does not work after the virus infection?
What is the infected file name, where was it found e.g. (C:\windows\system32\infected-file-name.xxx) ?
Check the avast! Log Viewer (right click the avast ‘a’ icon), Warning section, this contains information on all avast detections. C:\Program Files\Alwil Software\Avast4\ashLogV.exe
Why can’t it move it, what errors are displayed, e.g. file in use, etc. ?
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.
