Alright so I just got a PC from my cousin. It was infected really bad and just overall really horrible. I backed up the data and reformatted the PC. It runs great. What are some things you'd suggest to install to prevent them from fuburing it again. I have installed AVG because it's non-invasive compared to Avira that has pop ups. I just don't want to mod Avira and block the popups because something might break in the future. I don't want to get calls about petty crap lol. Is adaware still worth installing? I have installed Firefox with Adblock Plus plugin.
