Anti Virus Warnings?

Your Antivirus is most likely deleting game files.
We had several reports of this in the past and so far all occurrences were due to a false positive , which is when anti-virus software flags something by mistake. There are no known occurrences of any viruses or malware in the game files, if the game was downloaded from our Store.

If a warning occurs please let us know and, if you can, please report it to your AV programs manufacturer.

To temporarily work around such an issue you can exclude the game from your AV program or disable AV temporarily (disconnect from the internet). Please do so at your own risk.

Please be aware that after adding the exception you need to validate the game files to restore any that the AV deleted.
Here is a Video guide on How to Verify the Steam Cache ;

Here are some guides for creating an exclusion for a program in;



ESET Smart Secuirty

Virgin Media
(If anyone finds a better one please leave me a link, ta)



McAfee Firewall

McAfee Antivirus

Norton 360

If you are using a different AV then let me know which Anti Virus you are using and i will find you a guided walkthrough.

Hey Dog Life, sometimes turning these programs off doesnt stop them from blocking. You are best off creating an exception in your firewall;
