Performance problems after having installed new antivirus software

This monday I uninstalled my previous antivirus software, primarily because it had been expired for some time and I was adviced to get another. Former was Total Defense, current is Windows Defender.

When I had installed Windows Defender and started playing CoH, my graphics were acting up in the way of me only being able to see black silhouettes of my characters, with auras being the only thing colored. Also, when playing the game the movement in general are kinda stiff, like incomplete, if you understand. They feel different than usual at least, less flowing if you will. These problems occur while I play in Ultra Mode; while playing on Recommended and below the movement is more natural and less laggy.

In terms of trying to solve the problem I've tried both turning off the antivirus software and even turning off my Firewall, but all to no help

I am writing here hoping you people can help me solve this issue.

If your antivirus has been out of date for some time, I'd suggest some scans first for malware/virus's. Download and update, http://www.malwarebytes.org/ then run a scan. It only needs to be ran, then can be shut down. Then update/rerun it ever couple of weeks.

Also check some online virus scanners, housecall.trendmicro.com, bitdefender.com/scanner/online/free.html, www.eset.com/us/online-scanner, kaspersky.com/virusscanner.

I also noticed that McAfee Security Scan\2.0.181\SSScheduler.exe was running? Are you sure that Defender is the only antivirus product you've had on the system? Two antivirus type products will slow down a system, or cause instability.

Sorry for the long response, I haven't gotten around to trying it until now. Thanks for the tips however The malware stuff found a threat which I haven't been informed of elsewhere, so that's cool! Also uninstalled McAfee, but have yet to see if there's been a change in-game ^^

About the virus scanner sites, what effect would that have? Is it just a virus scanning software on the internet or would it have some other effects?
