CCleaner is causing VAC Authentication Errors in CS:GO

Everytime I run CCleaner, the game cs:go will work for a few minutes or hours, but then it will say an issue with your computer is blocking the VAC system and kick me from the game.

After it shows the error once, it won't work for about 20 mins, and then will go back to normal and I won't see the error until I run CCleaner again.

I have tried excluding the steam and csgo folder, but it doesn't work.

Is there any fix for this apart from not running ccleaner?

thanks

Haven't experienced this myself, did you check your machine for malicious software?

No viruses. I just installed Windows 10 yesterday. But it was doing the same thing when I was on Windows 7. :/

Does it happen with any other VAC enabled games?

Just CS GO. I had to uninstall CCleaner :(

Shame...

Since excluding the folders didn't work it might very well be something in the registry that needs to be excluded.

I used 5 years CCleaner 3 months ago I started playing CS GO and have same problem in ccleaner i have excluded steam but nothing helped. i see this problem has not resolved from 2015 year... Ok will unninstall CCleaner, sorry!
