The internet is a death trap for your computer i think most people who have delt with the internet have had problems with viruses etc. i had a virus before and i had to get my whole system re-started, cost me around £40.00 all together (money converted from euros) and i lost many of my programmes, pictures, music etc. and many other things i had been working on, i used to have Norton Antivirus, and to be honest it was useless and annoying, after i had that virus my anti-virus had to be cleared away, that was another £30.00 but this time i got BullGaurd it is fantastic! it has everything you want to stop viruses and many other hazards to your pc! i would certainly reccomend it. But i tell you, computers are an expensive do.
