or use a secure browser: read firefox + add ons and dont download stupid shit and run it...

being secure in your browsing isnt hard people

1) dont trust people with your account info
2) dont put your account info into any site unless you specifically see playonline.com in the address bar (phishing...)
3) dont download 3rd party stuff ie naked galka mod or something
4) run antivirus always up to date
5) have a firewall and no windows firewall doesnt count, something like norton or something, better yet get a hardware firewall
6) dont open any email attachments EVER unless you are specifically told by someone you know they are sending you something
7) dont use microsoft products besides windows, 99% of things that install from a website via scripting will only work with lolie, and lolie really sucks at blocking that stuff.... http://www.firefox.com is your friend, then get noscript and other stuff
8) dont transmit your password in plain text over aim or msn or irc or something stupid like that, most of that is either logged on your pc, or easily sniffable as its typically sent in plain text
