As for this pf file, although I can't remove it, it doesn't seem to be doing anything.

Actually, I now see that I already have other mp4 videos which I have watched on Windows 10 before installing this recent application, so I don't know why the new file was problematic.
Still, working now.

Removing of invalid Prefetch entries. Old valid entries are preserved.

I might have a look at that. Certainly if I have any further problems with the file.

Re: Real Player installs Norton Security
JBRI might be wrong but a PF file just has writing on it and makes no difference to your Comp.
Just downloaded Priva Zar took a long time but did not lose any sites or passwords.
One point the first Virus and Hack happened on an Apple Comp back in the 90s
PS would not touch Norton with a barge pole

Re: Real Player installs Norton Security
About PF files: These are in the Prefetch folder to help programs open more quickly. No harm is done by leaving them there, it's just annoying that after uninstalling a program, files and Registry entries might still be left behind. If the computer uses an SSD, the prefetch function can optionally be disabled (a Registry job).I use PrivaZer. It keeps the system clean and may well clear out any leftover files and Registry entries after uninstalling a program. I have also used a program called 'RegScanner'. This seeks out any name typed into the search box and lists all the entries is finds. From there, they can be deleted all in one go, which can save a heck of a lot of time.
There are many who say never clean or mess with the Registry because it can potentially do more harm than good. This may true and we all take our chances ..but I think cleaners are better these days at determining what are needed or unneeded Registry keys. The danger is that if the cleaner gets it wrong and automatically removes needed key, or if a needed key is manually removed, then the system or an installed program might suffer.
If work in the Registry does cause trouble, there is always System Restore. Look into how to back-up and restore the Registry manually as well. Keep a full disk image backup, read how to restore from it and be ready to use backups if necessary.

I don't think anyone would touch Norton... without PPE.

However, I do have a full image backup on two external hard drives (twice) and a restore CD.
