Hello,
There are several odd processes running on my PC. They have no description or username data. When I click "properties" or "open file location," nothing pops up. These are,
csrss.exe winlogon.exe atieclxx.exe

I realize that the former two are typical windows files and that the third is related to my ATI card, but I haven't seen these running before - or perhaps I have, but with a description and user data. I've heard that some types of malware pose as these processes.
Recently, I've noticed huge spikes in CPU usage (often reaching 100% and constant use of upwards of 50% of my computer's memory (although I have 3-4 Gb RAM, and my only memory intensive programs are Chrome / Skype / Steam). When I put my computer in sleep mode and turn it on again, sometimes the machine will turn on, the LEDs on my mouse/keyboard will turn on, the monitor remains unresponsive and the CPU light doesn't flicker. I forced shutdown once, and received a BSOD. When I rebooted, I didn't see a typical login screen - after the boot screen disappeared, the screen remained dark for 45 seconds, and suddenly showed my desktop as it was when I put my computer in sleep mode.
I've run scans in Malwarebytes, AVG and Microsoft Security Essentials in safe mode and found nothing in AVG/MSE. However, Malwarebytes found some spyware, which was deleted. However, I still notice these spikes in CPU / Memory usage, and the three processes are still listed and running. After a few searches, this seemed similar, but I haven't noticed any spam, except for Google Chrome changing my search engine from Google to Blekko -- however, this may have been a default process of one of the anti-malware softwares I've downloaded. But I am not entirely faithful that that's the case.
If you have any tips / suggestions / instructions / words of advice, I'm all ears. Thank you in advance for your help.
