Registry Cleaner Removal

A virus called XP smart security attacked my computer. I did all the steps listed on this website http://www.bleepingcomputer.com/virus-removal/remove-smart-security except for the last one that said delete my system 32 file.I’m nervous about deleting that since I heard it’s a very important component for a computer. Anyway, I also downloaded and ran in safemode Malewarebytes,Wondershare Registry Optimizer, Spybot-search and destroy, AVG 9.0 Anti-virus plus firewall, and Auslogics Registry Cleaner. The problem is even though I know the virus is gone it has left a lot of problems in its wake even with all the computer helping stuff I downloaded.

First I can no longer do anything under my username. It is the name I was under when the virus attacked. If I try to open the internet or go to control panel these two things will pop up. A box saying Open with comes up and then proceeds to list programs. That box shouldn’t be coming up in the first place,and even when I go along with it still no internet. For the control panel this message comes up C:/windows/system32/rundll32.exe/application not found.

Strangely this doesn’t happen in my other administrator user-names. Just the one that I was on when the virus came. However, there are some problems under the username I’m now under as well. Firefox will crash if I go to certain sites or I will get redirected. Also I can go to safe mode, but I can no longer do anything while there. I have a strong feeling this virus rewrote some things in my registry, and even with the registry cleaners I used I’m still having problems. What am I doing wrong?

Should I I go on ahead and do the last step in the link I provided which is deleting the system 32 file? That does seem like where the problems are coming from since all the errors I keep getting have that file name in it. If not what can I do? Everything is wrong or won’t work at all under my original user-name. Even system restore. My other user-names aren’t all that better. What can I do to get my computer fully back in good health. Thanks

Do you happen to have your windows disk or a recovery disc? If so insert it and select repair. If not and you don’t have a backup and system restore won’t work then I’m afraid your most likely screwed.
