Hi

I have had a look into this and it sounds like you may have picked up some malicious software.

I would recommend you follow this guidance in this link that will walk you through how to remove malicious software and how to keep safe in the future.

I hope this helps, but if not, please come back here and we can look into a different solution for you.

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.
