@ Bob, Understood about contacting Prevx (your post 32)
@ Technical,
I always disconnect from the internet and stop all running programmes before installing any new software, including avast! Tauscan, etc. Just a personal preference thing. I haven't had any problem with avast! Prevx and buffer over-runs.
The reason I disconnect from the internet, is that some programmes after installation require to contact home for updates, I prefer to ensure that the connection is made after my security programmes are up and running first.
Having to stop Prevx during an install isn't much of a problem in that case.
