safety first

after the bad experience i had before, i have decided to download more internet security softwares for my computer, the first thing i did after getting it back from the tech guys was downloading AVG free edition and ad-aware 2007, these are could be said to be the best from the bunch of free anti-virus and anti-spyware programmes out there, i've tried avira antivirus but i felt that by actually having that software is more troublesome than having a virus itself! the last time i used it, it lagged up my whole computer and i had to uninstall it, other than that, mozilla firefox, and McAfee site advisor were to come, so far, my computer is running fine with all this protecting it.
