how do I prevent viurses on my computer?
Some companies let you download a basic version of their virus scanner software free if it's for non-commercial home use. The only two I can think of are “avast!” and “AVG”, but there are probably others if you search for them.
norton takes up a lot of the computers proformance...although it is a very good anti-virus...I prefer advast
you can get norton antivirus account but you have to pay for it but it is worth it!:)
Buy a mac or install antivirus software and don't click on any site you don't trust.
