MalwareBytes not starting up, chameleon getting stuck

Recommended Posts

Yesterday, My firefox stopped working. It hangs on startup with the error message telling me it was a stackhash issue (StackHash_7918).

I downloaded chrome, and this also does not start (no error message). I found out that this was something to do with execution prevention, but i was not fully convinced, because it has worked for years before now. I tryed reinstalling firefox, and nothing.

So i did a little bit of poking around. My computer was protected by Norton 360 (pls don't flame, i'm not an antivirus expert). I found out that Norton was not updating correctly, and was exhibiting odd behaviour (creating lots of exceptions in my firewall, not deleting trojans when it said it had deleted them etc.).

My next step was to reinstall Norton, but the same problems were occuring, so i uninstalled it completely and have now downloaded malwarebytes.

My computer is clearly infected because malwarebytes refused to start initially. I used chameleon to start it and on its initial scan malwarebytes told me it had found hijack.userinit, and needed to restart my comp to delete the virus.

Upon restarting my computer, Malwarebytes still won't start up (it just quits about 1/2 second after starting with no error message), but now chameleon gets stuck at "attempting to update malwarebytes". It comes up with 'connecting to server', tells me that malwarebytes is updated to the latest version, then 'connecting to server' then tells me it is updated to the latest version again and keeps repeating this.

Thanks in advance for your help
