i desperately needed to download Microsoft 2013 [because the FLOP 2010 student set didn't have publisher

] and i didn't have the money to buy it officially so i illegally downloaded it using some shady programs!
the program has successfully been installed... i thought everything was normal but now everytime i go on a forum and try to click something an extra tab opens up with multiple adverts [gambling/****/gaming etc]
im now scared to use ebay/facebook/amazon because im afraid they're gonna steal my details, can anyone who's been in a similar situation help me?
