With Google Chrome I can download patches and use the LIVE EDITOR on my laptop. My problem is Norton Antivirus blocks me downloading PC EDITOR.
I'm not tech savvy enough to trust turning off the antivirus software to see if that helps. The antivirus doesn't give me the option of accepting the download, it just deletes it immediately. I don't have this problem with anything else I download.
Any advice would be much appreciated.
Yep. As already stated: the PC Editor is NOT from Marshall Amplification so they cannot and will not provide support for it. I've also been using it for a long time with no issues as all (AVG Antivirus no problem). Your problem would be better detailed on Marshall Code Tools (https://marshallcode.tools/) which is where the software comes from. Alternatively: I can email it to you if you like (not sure if Norton will still complain when you try to extract the file and install) (but surely Norton has an option to exclude the checking of certain files)???
