I dubbed this the "Crazy Virus", because I have very similar results to "Joeyfixit's" post HERE
No internet connectivity, even in safe mode w/networking as Administrator.
Initially, could not install Malware Bytes (wouldn't appear to do anything, but would list in the task manager processes). Did the rename on the set-up file and it started to install. There would be a LONG hang on the finish, then pop up and ask to update and run. If I said OK, it would hang again. I said no, renamed and tried to run manually and nothing.
Tried SAS, get an error message says it has to close.
Tried SBSD, can't connect to internet to finish setup/install.
Followed other thread and deleted host file, but nothing changed.
Downloaded RSIT and posted Log HERE
