Hi,
For some time now player's on the COD5 NAM FTS have been chatting about PC/Browser/gaming performance issues... I've been running Win7 on all my laptops/PC's for better then a year now with no issues, thanks to the following utilities...
SUPERAntiSpyware Version 6.0 (suggested by Hunter)

Anti-Malware (suggested by me)

Advanced SystemCare 9 (suggested by me)

And yes, all are available as free downloads however I did purchase them... Moreover if anyone has other suggestion please charm in!
Take care...
