I recently installed Norton Antivirus for Mac 11.2.2. When I started my external hard drive, Antivirus immediately began to scan my TimeMachine backup partition on that disk.
It estimated 3M+ files to scan, but worked for two days and scanned more than 25+ files before the computer hung up (perhaps for other reason). When I restarted, the scan did not resume.
Is this common for TimeMachine backup files (which I have been keeping now for several years)? Or, is this a never ending scan? I'm afraid to start it again.
I'm having the same issue with scanning Time Machine. When I do a specific scan for just the Macintosh HD, the scan completes but if I do an entire scan which includes my Time Machine external HD, the scan never stops it reads 6 million files of 1 million files. This is the case if I just scan the Time Machine external HD alone.
You can follow the directions at the link given above and post your SymantecInfo.txt here if you'd like. That's the only thing I can think that may give a hint as to why it is hanging up.
On initial inspection I don't see any obvious problems, but will continue to look. I may have to try to reproduce this internally, but it may be a while before I have a chance to do so.
One thought is to try scanning with compressed file scans disabled, this should at least make scanning faster.
That was the first thing I did from reading other posts here is to turn off compressed file scanning it does speed up the scan but scan still never stops when Time Machine is scanned.
One more thing I would like to add as you are looking at the txt file is that the scan use to find and resolve tracking cookies consistently but in the past few weeks, it does not show anything. Every scan I do for just the Macintosh HD drive results in just "no viruses found".
I'm not aware of the cookie scanning you are referring to. Are you certain this was coming from a NAV scan? If you have an example in your NAV history that could help (just attach a screenshot, or I can tell you where the log file is so you could send it).
