I right clicked "Avengers aio" and run it as administrator. What can i do now to undo this?

Is this some supposed game that asked you to turn off your antivirus and run it as administrator? If so it will likely be malware.

If this is the case, please upload and share logs from Farbar Recovery Scan Tool (FRST).

https://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/

• Run FRST and press Scan.
• Two logs are created in the folder that FRST is run from, FRST.txt and Addition.txt.
• Upload the logs to OneDrive, Google Drive or any file sharing service.
• Post the share link.

Note: If you are downloading FRST with Edge, smartscreen will initially block it.

Click on the 3 dots next to the warning and select Keep-> Show more-> Keep anyway.

If this isn't suspected malware, restart your computer.

If it was actually a game all you would need to do is end the game or sign out of your account and back in.

If you think it was malware, download the scanner I linked in my previous post (FRST).

Run FRST and press Scan.

When it finishes scanning there will be two log files.

Upload the log files to your OneDrive.

Post a link to the logs with your reply.

Yes it's from a game. And i didn't understad what you said. Is there any other way?
