I have a PC here in the shop that looks to have a corrupted winsock. There is some global proxy setting on the machine that wont let me change the internet explorer proxy settings for this one user. I downloaded combofix and removed a bunch of stuff, and cleaned this machine of adware. When I go into firefox and disable proxy - I can get out to the internet with no trouble, but unless I can fix Internet Explorer 8 on windows 7 - I can't download quickbooks, java and flash updates. Is there a tool that I can run that will do one solid sweep?
