Hello Gerry Giraffe
Gobbledygook is never a good thing. This does have a possibility of being just registry corruption. However sence it does also have a possiblity of being malware and system restore could hinder the malware folks on checking for malware.
I suggest you go to the
Malware Forum and run all the steps located in the
START HERE. These self-help tools will help you clean up 70% of problems on your own. If you are still having problems after doing the steps, then please post a HiJackThis Log in
THAT forum. If you are unable to run and/or post a HJT log, then post that in your initial post in the topic you create in that forum.
If you are still having problems after being given a clean bill of health from the malware expert, then please return to
THIS thread and we will pursue other options to help you solve your current problem(s).
In the mean time I will look into what to do besides system restore to fix this issue.
