I think that PG is gerat as a defense against unknown threats.It has always asked me to think over letting different files to be execured on my PC.When an antivirus fails to see a threat,PG alarms.I cionsider ProcessGuard to be a must soft for a home user.
But ProcessGuard 3.2 is availible already.

This programme asks you for permission to exucute a file it finds suspicious.It makes one feel safe.This soft should be a must progy on any home PC.

Firefox 1.5.0ю1 is a very unstable programme.When I open several pages simulteneously ,Firefox crashes almost every time and I lose downloaded pages.I reinstalled the programme-the same result.May be Firefox has some pleasent features,but cons are stronger.The only feature I like is a simple,automated process of import of favourites into FF.But in general Firefox seems to be a raw and undone product,requiring a bunch of plug-ins.It is not a software programme meant for an ordinary Joe or a house-wife.
I remember all versions of FireFox starting with 1.0 to have been unstable,inclined to crash.Even after installation the other OS crashes didn't stop occurring.
I would not advise my friend to make use of FF.I am looking forward to seeing new releases of FF,which I hope will be more superiour from the technical point of view.
