Well, I've been using XP pro for some time now and have continued to use Grisoft's AVG. You can be happily surfing the net and suddenly a polite little notice appears that some so and so has deposited xxx virus in your internet temp files folder. Clear the folder, run the checker and get the all clear. I double check occasionally with housecall and have never yet failed to get an all clear here as well. Recently updates have been coming out of Grisoft's website on a daily basis and with broadband, updating is an automated doddle. What is even more important is that the AVG virus checker is completely
FREE!.
