I've just installed this and ran a scan where it revealed Realspy & Sherlock Keylog. These are both keylog spyware.

Before I ran the Arovax scan, I scanned my computer with Avast anti virus v4.7; Ad-aware 2007 (free edition); Spyware Terminator; CC Clean; Panda AntiRoot kit and Web Security Guard. My PC is also protected by Comodo Pro Firewall V.3 and Comodo BOClean.

Non of the aforementioned were able to prevent or reveal the the 2 key loggers except Arovax AntiSpyware.

So I have to strongly recommend it.
