I have been a geek when it comes to computers for 30 years now (and after working that out I feel very old)
I started out with a ZX81 then moved onto an Atari St also having an amstrad pcw. before getting a windows 3.0 based machine.
Built my first PC with a p1 166 that I overclocked to run at 200MHz that had a huge 196 MB of ram
In the good old days Norton was the best, but it has slowly got worse and now if I get asked to look at a friends computer if its not running right the first thing I do is disable Norton, and I am sad to say 9 times out of 10 that solves what ever the problem is.
I run AVG and Avast on my home computers, A hardware firewall in my router. and something I have done for many years is map all the drives on my network, and set my antivirus software to read mapped drives (All my PCs run xp pro) I scan 2 times a week. but not at the same time. the reasoning for this is, if 1 antivirus misses the infection the other will find it (fingers crossed). And the only time I have had a virus was when I did something stupid and clicked on a link I knew to be infected. The virus was cleared pretty much right away but the antivirus on the other machine.
Norton? good motorbikes Bad antivirus
