Windows 10: I think I was scammed by a tech support company. I let them remotely

They ran a command prompt dir/s scan with letters in red. I was told there were many errors and on the bottom line was a line that says my computer was hacked by the koobface virus.
They told me it would cost $300 to repair so I thought it was a scam. I broke the network connection and hung up the phone.
I then ran a command prompt scan with admin rights, the same dir/s scan and saw no warning about the koobface virus..
I then noticed that they had placed two new programs on my computer, Supremo and Show my computer.
I went to add/remove programs and neither were listed.
So thinking they were a virus I jut deleted them and deleted the recycle folder.
I wonder how much of a problem that I caused.
Any advice would be appreciated.

I think I have been scammed by a company that is claiming to be Microsoft Tech support.

Do not respond to any email that you get saying you need to do something.

Run Windows Defender and MalwareBytes if they say things are wrong with your computer.

Do not click on any of the places in email that say click here. Look at the email address of the sender and it may be from another country.

I learned a long time ago. I am almost 83 and started in PCs with a model one Radio Shack which was called a Trash 80. I had been working with main frame computers before that.

Microsoft will never contact you unsolicited by any means. Yes, you should
contact your financial institution, or credit card co.
as soon as possible. Tell them you were scammed by a phony tech support company. They'll stop payment, remove the charges from your acct., or whatever they need to do.

It'd be best to have someone do a clean install of Windows for you. You don't ever need to renew any Windows registration.

You can report them, after you get the rest taken care of.

I would start by doing some online scans provided by several known av vendors (eset and such). I would also run some antimalware software (MBAM, Adwcleaner, etc).

Important: Before running the adware cleaner, you should run Rkill by Grimler, (you must run it with ADMIN RIGHTS), but don't reboot after running it. Here is an alternative version for those malware that tries to kill it.

 

I know you don't want to hear this, but if someone had access to your computer, they could have done anything. Your best bet is to wipe the drive and re-install clean.

To quote a favorite movie:

Corporal Hicks: I say we take off, nuke the site from orbit.
[looks to Ripley]
Corporal Hicks: It's the only way to be sure.

 

How did he did he remote into your computer, did you install a program for him - If you did goto add remove programs and remove TeamViewer

Another way to remote is buy sending him an email with remote assistance,

 

Nothing to add, just to say that I completely agree. Either restore a recent system image or clean install.
