PC had a virus I used antimalwarebytes as well as hijackthis and cleaned it up. I see no other pieces remaining or running. However in internet explorer after the virus it has setting to use proxy server like most browser viruses do. So I changed setting back to not use a proxy server but after a day or so the setting comes up to use a proxy server. Its driving me mad.

on programs tab of internet options look for "manage addons" button.  In manage add-ons, if there are any BHO or browser helper object that you do not recognize, disable them.

If that doesnt work, you can also disable the proxy in the registry.


[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]
"ProxyEnable"=dword:00000001

Change the ProxyEnable to zero, to disable the proxy.

What have you cleaned the machine with?

If you havent used the below, I would try so.... You are still infected, probably with a Rootkit..... TDSSKiller above might even get it....

MalwareBytes
http://www.malwarebytes.org/

Hitman Pro
http://www.surfright.nl/en

Dr Web CureIt
http://www.freedrweb.com/cureit/?lng=en

NO security scanners detect everything..... Some infections take a multi pronged approach......

Thanks for the info I ran the programs you suggested and it found a few lingering pieces of malware. After removing them it has been two days without resetting so I think it has been resolved.
