I also have Spyware Guard installed - it sits in the System Tray and, apparently, is supposed to protect against malware whilst you are online. I think I got it from a PCA disk. I have looked at the Log and it appears to be working and checking for browser hijackers and BHOs. The web page no longer works and updates haven`t been available for some time so whether it is worth having I shall leave others to advise on. But it doesn`t appear to interfere with any other software on my machine.
