Well,

The autorun.inf is bad news being in the Windows root directory.

You will now have to scan all your removable media, as that is what they go for.

I would also recommend that you clear your restore points. Your AV will not be able to clean them

The .com files look like a revamp of h.exe and i.exe, which are malware.
