Before doing anything further I would recommend that you check the computer for malware, please see GTG malware redirection details below;
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).
If you do need to start a thread on the Malware Forums please include a link to this thread in your OP there so the security experts can check what steps have been done here, thanks and good luck.
