After one of my computers recently became seriously infected with viruses and the only way to completely get rid of them being a reformat as quite a few of the OS files and Anti virus files being infected, I saw that you could buy a U3 enabled flash drive which you can get a copy of Avast for.
The problem now though is that the only u3 enabled drives that I can see on the market DO NOT have a write protect switch therefore the anti virus files there could equally be infected, so if anyone knows of any with such a switch could you let me know?
Cheers
