Do I really need any protection software on my computer?

Really I dont care if I get any viruses infact I reninstall Windows Vista every week! Dont ask why but I just do its almost like a habit! Is it bad for the PC?

Also the reason I dont want any protection utilities is because of my computer performance! I just want to to be and STAY fast! If you can reccommend any ANTI-VIRUS firewall ect. (whatever I need and preferabily one that is free) that will not slow down my computer, I will GREATLY appericiate it! thanks!

If you want your PC to stay fast, then you need security software.

Viruses, and spy ware slow down a PC to about 1 tenth of it's performance capabilities.

If you don't mind waiting 10 minutes for your PC to boot up, then don't worry about getting any security software.

No, you don't - and I mean that sincerly. As long as you truly do not care if your identity gets stolen (could happen?) or if your computer shuts down and stops working...
