Operating system problem

Can't run MS Security Essentials
Malwarebytes picked up 18 infections
I am now downloading rescue system program.
Hopefully I can get some functionality back again.

Perhaps after you have removed those previous infections, you can now run Microsoft Security Essentials

Rescan and Remove All with Malwarebytes.

Well done. It seems as if your PC is behaving normally now. Be sure to do regular scans. I suggest you keep the following resident on your PC:

MSE

and run MBAM (Malwarebytes) regularly.

And a decent firewall. Make sure windows firewall is enabled in case malware disabled it.
Also, if i remember right, there was also a DNS changer trojan in your pc. Be sure to password protect your settings in your router configuration.
At last, not least, glad it's solved.

Excellent.

Glad you have things repaired.

Some viruses may disable some settings, so if you notice something is messed up and your scans don't show any viruses, google your problem. I had a virus once that disabled task manager, and a quick look up gave me the solution.
