Hello,

Realistically, I don't trust single-point failure systems, ie only one antivirus program.

I have use (at the same time):
1. norton and antivir (excellent together)
2. f-prot and norton (a little bumpy in certain areas)
3. f-prot and antivir (also a little bumpy)

The bumpyness was when both were full scanning at the time.

Why more then one? European viruses travel at a different rate then US viruses. AntiVir (Germany) would have an update 12 to 24 hours before the US venders. Same applies on the other side of the fence.

On my linux mail server, I have 4 (yes FOUR) different virus scanners updated hourly just because of the spread rate based upon origin.
