Smart Autorun Cleaner is an autorun malware removal app that can clean infected disks and restore hidden files.

On startup, you can decide what to do as new devices are discovered. You can decide each time or choose to scan silently, and, of course, to not ask again for that drive.

As you insert removable media, it can detect, collect data, scan, and restore files and folders if needed. A handful of options are also available to tweak how scanning is done.

Smart Autorun Cleaner was once shareware with a 500-minute limit but a free lifetime key is available for everyone:

Smart Autorun Cleaner should be portable, but still, it's a niche app for anyone having difficulty removing autorun malware.
