wasd keys freeze the gameplay

[Zevman]

I cannot walk or drive tractors, w,a,s,d keys freeze the screen for 3 to 4 seconds, looking around with no problem when game resumes. I removed all mods, uninstalled fs 2013 reinstalled, paid for another fs2013 on steam still the same. paid for fs 2013 again reinstalled all up to 2.1 with titanium, added. little mods added which from official site. Prior to game install i made sure of lastest drivers on mouse, soundcard, video card, keyboard, widows, all up to date. log text file included. I can play Skyrim, DayZ, and walk around star citizen hanger with no problem. I've also change the between 3 keyboard the has usb connection. Has any one had or have this problem and fixed it? Thanks

Gameplay now solved, it was my antivirus software causing the the wasd freeze. So if you have this trouble have your antivirus exclude and let it write and read. Thanks
