Thank you for your understanding.

I have x 7 PDF:PhisingX-gen and JS:Pdfka-gen files detected when doing a Deep Scan but the AVG Antivirus is unable to quarentine them.  When I click on them for more information, it says they may be protected.  How can I remove them manually?  They are all in System/Volumes/Update/Users/…
I have an IMac and I can't find the files when searching with the Magnifying Glass Search tool.

Any help will be appreciated.
