PLEASE HELP! dnsChanger will not go away!


Recommended Posts

My home computer is infected with the DNSChanger trojan virus, and none of the methods i have found on here work in eliminating it!

- The virus is blocking the malwarebytes website, so I can't update malwarebytes through the program (I have downloaded the newest rules.ref file at work and emailed it to myself at home to install the newest rules file. but it does not remove the virus.)

- The virus has blocked the trendmicro website as well, so i can't run housecall (housecall.trendmicro.com)

- malwarebytes finds 2 infected files and quarantines/deletes them, but they return when i restart my computer. (please see below)

- i have run combofix as suggested in other forums - it also did not fix anything

PLEASE HELP! This is driving me crazy!!

Thanks,

Thomas
