1. Press the Windows key and R on your keyboard and a window will pop up.
2. Type MSCONFIG in the box
3. Go to "Startup" tab
4. Press "Disable All buttons". If you don't want to disable your antivirus at startup, just tick that box. Now tick the Akami Net Session boxes to turn it back as AVA runs smoother with it on. Certain AV's will come back anyway. I always switch my ESET Nod6 to Game mode or turn it off while playing AVA.
5. Clean your LOG and XIGNCODE files again as shown by Chrome Boy in Tutorials. Even try CCleaner to clean up your PC.
6. Now restart/reboot your PC and then start AVA.
