Problem after deleting file following AVG scan

[AlanH]

A couple of weeks ago AVG Free Edition discovered and quarantined a trojan. Foolishly (?) I deleted the file from the quarantine folder in AVG. Now, on booting up my laptop, I get a window with the following message "Error loading C:\WINDOWS\system32\atgban.dll. The specified module could not be found". Is there a way I can fix this and get rid of this message? Thanks.

Try a registry cleaner like CCcleaner http://www.filehippo.com/download_ccleaner/
