It started with HDD defragger and Antivirus Action viruses. The Ffox browser was also hijacked. The rkill dot com and Malwaregyte's antimalware programs seemed to find the problem and fix it.. However upon reboot, i find out that the Firefox crashes almost immediately. But I also get multiple error messages that say that Internet Explorer has stopped working eventhough I didin't try to run IE, in fact I tried to disable the IE by going into Tools in IE and changing the setting to go to Manual Proxy server 0.0.0.0 etc.
This is a brief summary, I have tried many other things and would appreciate some help
