major malware removal job, now computer is running slow

[tasnan49]

was sent here by a nice guy at forum malwarebytes who helped me over 10 days/nights to free my Windows 7 desktop of malware and other nasties. Began with a black screen with cursor and no other display. Well now I am free of all that, the computer is slow slow slow. Browsers take ages to load, everything does. Have reset all browsers and removed add ons, no change. Am running ESET Smart Security, Malwarebytes Pro and Anti-Logger Free Protection is on so don't believe there is any problem there. PC is a Dell I got in 2008 - maybe I need a new PC? what suggestion do you have? I do have Windows 7 upgrade disk and the Vista one that came with the PC.

any help would be appreciated, thanks in advance and expectations..................

Try following this guide to repair windows. I know that it is for Vista but the procedure should be similar to 7. If all else fails you might need to reinstall Windows. Repair Vista Options - Preferred Sequence

I have a problem is that my Windows 7 is now with sp1 of course and the original disk has no service pack. I tried to do install within windows earlier but it said the one I am trying to upgrade is later than the one on the disk. there is no way to remove Service Pack 1 is there?

You can use vlite to slipstream sp1 into an install disk however you should still be able to boot into your disk which would be the best way to perform repairs.

You could just download an ISO with SP1 and make a new disc,
