Kay Didion says:
I’m running 2 machines with WinXP SP3 and WinRAR 3.7.1, which I use very frequently. One day one machine had a runaway process on boot-up, and launched around 400 instances of WinRAR all of which generated “Corrupt archive” messages. My virus scanner, which is up-to-date, was silent on the issue.
I tried restoring the system to an earlier profile twice with no luck. I uninstalled WinRAR (using Control Panel > Uninstall), and deleted the instances of WinRAR in Windows\Prefetch. I also edited the registry, removing all instances of WinRAR.
On reboot, the problem was gone.
I did in-depth virus scans on both machines on completion of this clean-up.
Three days later my second system had the same problem on boot-up. This time I just uninstalled WinRAR and deleted Windows\Prefetch\WinRAR.exe, and rebooted. The problem went away without the additional work in RegEdit and System Restore.
I re-installed WinRAR from my original media and everything is back to normal.
I have no idea what triggered the events.
