I have just spent the weekend at my sister's house after she called me about a problem with her computer - it was running slow and acting up & she wanted a cd re-writer fitted.
Her daughters had been accessing the internet, without basic firewall or anti virus protection for the last 2 years, and I found 406 viruses and 185 spyware problems!
Anyone beat that?
I think viruses avoid mine cos it's SO slow. It took about four hours to download 19 security updates the other week (obviously I regularly check that it needs updating).
I've got a special device for mine - it's called a wooden mallet and I swear one day I'll use it!
To err is human, to really foul things up takes a computer.
