Hello everybody! I'm new to this forum and I hope someone could help me out. My friend have an Asus with Win XP and he's totally dumb with using the computer: I've told him he needed to download VLC to see some files I've sent him. Off course, he didn't got it from the official videolan.org website but from a crappy *****ic site (he told me he thinks that is this one, not sure btw). Installing VLC required also to install the Iminent toolbar which was removed from Firefox later on. Problem: when surfing the web with Firefox, randomly pages with advertising open up. This was not happening before this install and it was on popup-free website (facebook, google). If feel guilty for letting him download VLC but... Isn't it obvious that you have to download it from the official source?! Anyway, now I need a solution to fix this problem. Unfortunately, I'm a big Applefag: I can do almost anything on a Mac, I'm also good at coding but... when it comes to Microsoft OS I just don't know where to put my hands on! I've read about malware scan utilities but not sure which one to stick with. His computer is damn slow: opening a single window in a browser could take 3 minutes. So I think I can't go with random attempts, this is why I posted here: hopefully someone had a similar experience and can help. Thanks in advance!
