Computer has been running really slowly for a few weeks now, running Firefox for instance my CPU usage goes through the roof.
Few screengrabs to highlight this:
Never used to be like this and as you can imagine pretty much rules out using another program at the same time which i have never had bother with before. Only have 1.5gb of ram but that usually runs pretty smoothly.
First thought it was a Firefox problem so stopped using it, IE is the same even with 1 tab open, even Winamp and Media player causes the same carnage in the CPU usage. 1 program running like the ones mentioned and the CPU usage seems to be running at 90%+ with that program taking it all up.
Tried for help elsewhere and was recommended to use anti-virus, anti-adware/spyware programs and have spent the past few days running all sorts of them. AVG, Spybot, Malwarebot, SDFix, Dr. Web cureit. Tried so many and have now lost count. They found a few trojans, viruses and other niggly things - seemed to get rid of them no bother but still the problem persists.
One other fault i've been noticing, not sure if it's anything to do with this or not but:
When i'm shutting down i always get a popup saying 'Windows Cannot End This Program - c:\windows\system32\cmd.exe' forcing me to pick end this now.
Thanks for any replies in advance.
