Sophos Anti-Rootkit

One thing you always have to be careful of is rootkit installations. There are a whole bunch of them and they could take over without you ever knowing. Fortunately Sophos has come out with their Anti-Rootkit for download. You can do scans whenever you feel like and see if you’ve been compromised. It’s not the end-all-be-all for Windows, but it’s a start in protecting yourself.
