Constantly getting ads on safari/firefox/chrome. Brother downloaded a file and have tried EVERYTHING to find this malware but cannot. Can a factory reset help at all?
Alright so a few days ago my brother used my laptop to download Super Bowl 48 (huge seahawk fans). He torrented it offline, however now whenever I use Safari/Firefox/Chrome I get CONSTANT ads and pop ups. I have tried everything. Clearing extensions, uninstalling everything he did, scanned my computer with Clamxav, iAntivirus and even a free trial from Norton's latest software. Nothing, yet the problem still remains. From what I've heard/read, if I take it to the apple store they cannot help. Is a factory reset the only way to go?
Links are double underlined in green, and when I move the mouse over them
they pop up into an ad
This is the homepage of www.bleacherreport.com full of ads that were never ever there before. (2014 ford, play now/download/ video on left).
Simply very annoying and I have noticed a slower speed to my computers processing of webpages. please please please help!
