Last week I renewed my AVG licence for AVG Internet Security. I've also upgraded the 2014 version to 2015, but I'm now regretting that.
I'm experiencing an extreme drop in performance while gaming.

When I uninstall AVG 2015 it's solved and it runs smooth again.
What is the problem and is it possible to install AVG 2014 again, when I download the installation file from the website it automatically upgrades to 2015 while installing.

Chris, Further to Kishore Srinivasan's posting use the 32 or 64 bit install file from this webpage (http://www.avg.com/ww-en/download-2014.prd-isc). To determine whether your OS is a 32-bit or 64-bit, please click on this link (http://support.microsoft.com/en-us/kb/827218).
