Please, a free, trusty and simple antivirus for Windows XP to download, that's all what I am asking for...
I also try to do that, but everyone that I know, all my friends has at least 1,5 or 2 Giga Ram and at least a CPU with 2GHz. And not because they're rich or anything else, just it's somehow a standard here in my country. So for me, it's the average configuration. Here the bests are the Quad Core computers with 8Giga Rams (I had one at the beginning of this year for graphic work, but they're not a miracle computers as it's been advertised.).I try not to assume that everyone has the "best" of everything.
I have an original Norton / Symantec 2009 and at the previous Vista install I had no problem with that one at all (One of my former colleagues worked for Symantec and he gave me one to test it.). Also it's quite faster then the previous one. So it's not bad at all, but I still prefer AVG as it's free.
