hi,
this is intended to be funny
here are simple steps to infect a computer
when you complete all these steps you have a really nastily infected computer
1. use an unpatched version of xp with no service packs
2. never install updates
3. never use any type of protection, antivirus software is only for people who do dangerous things right?
4. never disable autorun, once you find a flash drive plugg it directly into your pc
5. frequently visit dangerous sites, nothing will happen to you anyway, your an advanced user
6. use a p2p program like limewire, bearshare, ares etc
7. whenever you see a pop-up stating that your computer is infected, click on it
8. click on links in your spam e-mails
actually the xp with no service pack should do the trick
but these others are just backups
if anyone else has more tips feel free to post them
