Command prompt keeps opening and closing

I recently just accidentally clicked on a link and gave me a ton of viruses. I ran malwarebytes and got rid of the ones it detected. The only issue is my command prompt, C:/WINDOWS/System32/cmd.exe, keeps opening then quickly closing. This happens around every 10 seconds.
I somehow managed to click on the command prompt and it froze, then disappeared. I took a picture.

I'll appreciate any help,
Thanks
