It is rare to get this issue, but if you do, there is a fix. This issue should pop up saying something along the lines of:
Quote:
Disconnected by VAC: You cannot play on secure servers
It will say more but that's what it mainly will tell you what the reason is.
There are a number of common software conflicts that can cause this error. If you are running any of the following software, please disable it while playing:
- CCleaner
- Powershell
- Sandboxie
- Cheat Engine
- IObit Start Menu 8
- Process Hacker
- DLL Injectors
- Hypervisors
- Steam Idlers
How to fix:
Step 1: Exit Steam (Make sure steam is not running)
Step 2: Press the Windows key + R
Step 3: Type the following into the Run box that shows up (making sure you keep quotation marks):
Code:
"C:\Program Files (x86)\Steam\bin\SteamService.exe" /repair
It may take a few minutes for it to fully complete repairing, but when it's finished, you should now be able to play on servers again!
