Roughly two weeks ago I started noticing performance degradation on my PC after downloading a game from a less than a reputable source. 

 

Symptoms: 

-Oddly (relatively) high CPU usage while nothing heavy is going on. (Rapidly changing between 4% and 20% at it's height, which is sort of high to my recollection of my rig's performance)

-System and compressed memory process at times eating chunks of CPU and idling at 400-600mb of memory usage. (For example, and relating to the next point: System and compressed memory shoots up to 25% CPU usage (no memory usage change) when running a test from www.speedtest.net, and FPS starts locking up.)

-System performance takes a nose dive during internet usage, effecting both FPS and audio playback, which has never happened in the past. 

 

Steps taken to attempt to rectify it:

Multiple scans, nothing of note coming up. 

-Bitdefender

-Bitdefender rescue mode

-Malwarebytes

-spybot search and destroy

-Rkill

-tdsskiller

-hitmanpro

-roguekiller

 

Everything is coming up rosey but the performance problem remains. 

 

Windows 10 x64 home

16gb of ram

i7 processor

nvidia gtx 970

1tb SSD drive

 

My computer is a gaming rig and shouldn't be suffering from problems like it is. My next step is a reformat but I figured I'd try my luck here first.

 

Edit: Not sure if it's worth mentioning, but a windows update, and a windows security update happened on 3/22, the same time period as the download, and about when the symptoms started. I've heard of windows updates doing funny things before so I'm not sure if related.

How do I get help? Who is helping me?For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear....Become a BleepingComputer fan: Facebook
