Autorun Deleter is a free program which disables and deletes the Autorun.inf virus. While most anti-virus can delete it, some may miss it – more so because it is a stubborn one and keeps coming back.
Autorun Deleter has been developed by TWC Forum member Paras Sidhu and you can download it by clicking here. If you have any questions its developer will be happy to respond here.
UPDATE: Autorun Deleter has been scanned at Jotti and the file is clean. If some AV's report it as a suspicious file, rest assured its a false positive.
