Have clearly got some kind of malware/virus. When accessing the web, searches on google will open in a new tab and redirect to other sites, normally to do with anti-spyware. All access to tech support sites is blocked - I'm having to write this from another computer - and AVG cannot connect to the update server (gives the message 'control file is missing')...

I read the 'New Instructions' post and tried to run Gmer.exe but all that happens is a little hang with an hourglass next to the cursor. That's it.

I realise this isn't much information. Not entirely sure what to do or how. Any help greatly appreciated,

Thanks...
