Computers can be fickle sometimes but having malware infection can have all sorts of affects on a computers behaviour.
Some malware is so deep rooted that not even a full format and fresh installation of the OS will clear it, I am neither qualified or permitted to assist with malware removal, this must be done over on the malware forums if it is needed, please refer to the GTG malware redirection details below and if necessary have the malware staff help you clean your system;
I suspect that you have some malware on your computer causing issues that we are not able to solve through means we can use here in the Tech Forums. I suggest you read the 'Start Here' topic found here. With these self-help tools you have a high chance of fixing the problems on your own. If you are still having problems after following Step 3 of the guide, continue with Step 4 and 5 and post in the Malware Forum. If you are unable to run any programs, Please create a topic stating what you have tried so far and that you are unable to run any programs. Also, Please do NOT post the logs in this thread.
If you are still having issues after the malware expert gives you a clean bill of health, Please return to THIS thread and we will pursue other options to help you solve your current problem(s).
