Moved to Malware Discussions.
In this case it's probably time to bring in some outside tools.
Boot into "Safe Mode with Networking" which gives you internet access in Safe Mode. You do that by tapping F8 repeatedly while booting up and it's the 2nd item on the ensuing menu.
Then download, install, update (important) and run the FREE version of THIS tool. It will do all that in that mode.
Let it remove anything it finds and reboot when asked to, then run it again in regular mode.
