I have a resident Trojan in C:\windows\system32\gxvccounter and can find no way of getting rid of the blasted thing! Can anyone give an answer as to how I can remove it permanently please?

I have the purchased version updated of malwarebytes and it finds it ever time and I can remove it from the results list but it keeps coming back over and over again.

Help please!!

Windows XP Home Edition. Malwarebytes up to date, AVG 8.5 up to date.

I have a Trojan DNS Changer gxvxccounter lurking in c:\windows\system32\gxvxccounter which Malwarebytes finds and quaratines from whence I delete it but low and behold, up it pops again and again and again! It is causing my computer to lock up and sometimes fail to turn off also it is playing havoc when I use Google as a search engine. I have tried SuperAnti Spy, Combofix, Autorun Eater and several others to remove this Trojan, all to no avail.

What I fail to understand is why, if Malwarebytes picks it up and quarantines it, will it not delete it permanently?

Does anyone have a solution to this problem, do I need to go after it manually and if so, can anyone send me detailed instructions as to how to go about doing this?

Your help would be very much appreciated.

Thank you.
