disconnect your computer from the internet now and run the scans in safe mode and stuff. the longer it's online, the more the can steal out of it; pretty much it's now a ticking time bomb
doing so should partially save your ass if they didn't already steal the everything out of your PC
change all your online accounts' passwords and stuff (obviously not on the compromised PC) and ensure two factor authentication is on (if you didn't use this, you really need to do this next time; almost nothing to lose and a huge gain in security)
also, your computer is pretty much permanently compromised from now on, so you might want to prepare to boot and nuke it and reinstall everything to ensure that it will be safe for future uses (not 100% required but we're aren't talking about adware or something)
