SVCHOST.exe using 100% memory and firefox redirecting

Hi
Im slowly working my way through the malware removal process.

When I startup the computer it runs very slowly. I opened windows task manager and there is an SVCHOST.exe that is using almost 100% of the available memory.
Also when I open firefox or internet explorer and try to go to a website it will open up another tab and redirect it to another random page.

I have been working through the malware removal process and have got to step 3: FireFox Browser Redirection Problems.
I have run GooredFix and have attached the results (I hope)

 

Have jut carried out Step 4 - All Browsers Have Redirection Problems
and run TDSSkiller. This seems to have fixed the problem so far.

Many thanks
