I get a crippling number of ads when I boot up Steam, all "Powered by AllDaySavings!". I downloaded this once after accidentally installing a shady internet re-upload of WinRAR. After realizing it was from CNET because it plastered me with offers, I immediately clicked "Cancel Install." Should've used task manager to kill it. After cancelling it quickly said "INSTALLING OFFERS..." and within seconds had Installed tons of adware all over my PC. With various adware and virus killers and browser resets I managed to get rid of them all throughout the week, excluding Steam. I've had these in Steam for a year now and nothing I do can get rid of them.
Steam has 500 GB of games on it. I can't reinstall.
