torjan.gen.2 and bad service.exe file help required please

Hi Forum
I have had a read around and it seems the best way to get assistance is to post a new thread with my issue.

the trojan.gen.2 keeps popping up on my Norton every 5 minutes or so and I am getting google redirect pages.
I have reset all the settings in IE through Microsoft but it hasnt resolved anything.
Also when I was running AVG it kept informing me I had an issue with service.exe file

Any assistance and advice with this would be much appreciated.

Many Thanks
