Hi,
I had this problem once and had to Google the solution, so hopefully I can help with this.
Go into settings and choose "advanced" in the top right hand corner.
Then click on Antivirus in the menu on the left hand side and turn off antivirus protection.
Then go to Quarantine and restore the file.
Go back into your settings under Antivirus > Tuning and put a check mark next to "Skip files/folders".
Then click on "files/folders", click on the + icon in the new window that opens up, navigate to the file and click ok to add it to the list of skipped files.
Then turn the antivirus protection back on and it shouldn't quarantine that file anymore.
