Trying to work out if disable antivirus was a joke or not?
Don't disable your AV
Update your AV to the latest definitions and run a full system scan.
If you don't have it already, download Malwarebytes and run a full system scan, if you do have it update it and run a full system scan.

After each scan shut down and restart your computer. Let your AV remove any infection found, if it finds something after restarting your computer perform another full system scan until nothing is found.
You can also use online scanners if you feel necessary
