Repair option not working

I just purchased 1 year coverage and scanned my PC. A high threat was found but when I attempted to use the “repair” option it did not work it only allowed me to use the option “move to chest” is this safe? Also, do I have to manually go to the file location to remove the file?

1/
What is the name of the file that is causing this particular issue?
2/
Do you recognise it as something you have downloaded, installed recently or have used at any time?
3/
Is it in the system files IE: C:\windows\system32.… (As a rule never delete files in this folder or you may be looking for problems.
