MJ Registry WatcherMJ Registry Watcher is a simple registry hooker/poller and file poller, that safeguards the most important startup files, registry keys and values, and other more exotic registry locations commonly attacked by trojans.

It has very low resource usage, and is set to poll every 10 seconds by default, although you can adjust this to anywhere between 0 and 600. A configuration file stores all your settings for future use. MJRW not only polls the registry, but it also hooks it, so that most changes to keys are undone and reported instantaneously.
Key deletions are still caught by the polling loop though, since they cannot be hooked. Exactly which keys and files are protected can be completely configured by the user, although the sets supplied with MJRW will cover most standard PCs.
