Unfortunately, excluding the STEAM folder does not work. Ran CCleaner earlier, started a ranked match and was kicked out / banned after 7 rounds.

Thanks - will give it a go. Somehow completely missed the exclude tab.

Hey guys, Been using CCleaner for years, but it seems that either an update from Valve's end or CCleaner has caused problems. Everytime I run CCleaner now - the next time I play a match of CS GO - I'll get 'VAC Authentication Error' and be unable to reconnect resulting in a ban. This is with 'Steam' de-selected in the application options before running CCleaner. It took a while to find the cause of the issue but it seems to be a common problem: http://steamcommunity.com/app/730/discussions/0/620712999982091539/ https://steamcommunity.com/app/730/discussions/0/620712999982924733/ https://www.reddit.com/r/GlobalOffensive/comments/35bin7/vac_authentication_error/ Is there anyway we can strictly stop CCleaner from touching CS GO / Steam files? Thanks!
