I was looking for a PDF reader and ran into a virus masquerading as a PDF reader. It hijacked my browsers, installed Yahoo as Chrome's default search engine, attached a bunch of plug-ins onto Firefox and installed "Worldoftanks" on my computer. Is anyone familiar with this virus? If asked I'll post a link. I should also note that Malwarebytes picked up about 44 infections and removed them. I then scanned again and it picked up two additional infections. When I tried to uninstall the "Worldoftanks" file it installed I couldn't find it in programs and features.
