I have a free antivirus that came with my ISP, (Charter). It is called F-Secure. I have loaded and reloaded it and it fails to update itself. My MS virus software ‘monitor’ (Windows Security Center), keeps reporting problems with it. I also seem to be getting quite a few viri. Perhaps I should trash this and install the Microsoft program.
Ask some of the people who replied to this thread before doing anything. I have SpySweeper, I pay $20/year.
