Recently I threw out Norton and installed Zone Alarm. I am have a regular daily problem (and so are others) that I now cannot complete a virus scan without the ZA True Vector Internet Monitor shutting down and the anti-virus scan hangs. Their tech support have not responded yet or provided answers to others with the same problem - seems to have happened after a recent update - I haven't been able to do a complete anti-virus scan for a few days now. So I thought I would try F-Secure. However, when I tried to install that, F-Secure wanted to uninstall Zone Alarm, Spy Sweeper and Spybot.

Spybot picked up a few things missed by Zone Alarm and Spy Sweeper.

Is there any known problem with F-Secure, Spy Sweeper and SpyBot coexisting? F-Secure will not continue installation unless I say it is ok for it to remove Spybot (and the others). That means I can only revise my security by uninstalling everything and then start with F-Secure. Does anyone have experience of this kind of co-existence? Also, other suggestions of high quality combinations much appreciated.
