Any idea why QuickTime won't open certain files on remote site?

I have an iMac Intel Core i5, Mac OS X, version 10.6.8 to which I transferred my PC files in June 1011. I apparently imported some mischief from my PC at the same time. Recently I installed more ram and have a total of 12 GB now, a new Linksys 54GL router, Comcast came by and upgraded everything and I have broadband. I put the Symantec folder in the trash and emptied the trash but still when I type my email into the site in order to access the link the Norton icon pops up and offers to put my info in for me. However, it has two incorrect email addresses both misspellings of my actual email adddress. Could Norton be messing up my ability to access these files?


I spent money on the program and can access 2/3rds of it but not Parts 5 and 6. I've spoken with the IT person at the site and he has double checked everything on his end. Other people can access all the Parts of the program, just not me. Any idea of what I could try to correct this situation? Would running ClamXav be the next step? Have any other suggestions?

    I've read your post three times and still don't understand what QuickTime (the Mac's built in media player) in your title has to do with Norton. Norton what? Where does that come from?

    Get rid of Norton.



    Norton Antivirus (made by Symantec) has a very long and illustrious reputation for mangling Mac OS X systems, sometimes to the point where a complete reinstall is necessary. Among other things, it installs kernel extensions which are known to cause kernel panics and system freezes; it contains known and documented bugs which can silently corrupt Adobe Photoshop and Adobe InDesign files, destroy a user's ability to authenticate as an administrator, and (on PPC systems) can cause Classic to stop functioning; and Symantec has on at least two occasions now released flawed .dat file updates which erroneously report certain critical Mac OS X files as "viruses." (Deleting these "viruses" causes damage to the system that in some cases renders it unbootable.)

    There are many forms of ‘Malware’ that can affect a computer system, of which ‘a virus’ is but one type, ‘trojans’ another. Using the strict definition of a computer virus, no viruses that can attack OS X have so far been detected 'in the wild', i.e. in anything other than laboratory conditions. The same is not true of other forms of malware, such as Trojans. Whilst it is a fairly safe bet that your Mac has NOT been infected by a virus, it may have another security-related problem, but more likely a technical problem unrelated to any malware threat.

    Can you provide a link to some of the files Quicktime does not play?


    Quicktime cannot play all kind of files natively, particularly Flash files.

    Firstly: delightful portraits on your web site!


    Can you please confirm what versions of OS X and Quicktime you are running?


    I don't want to register at but I managed to view one or two of her presentations without a hitch using QT 7.

  • Klaus1 Level 8 Level 8 (43,330 points)

    Try using QT 7.


    Mac OS X 10.6 includes QuickTime versions 10.0 and 7.6.3. The QuickTime 7 player will only be present if a QuickTime Pro key was present at the time of installation, or if specified as part of a custom install, or individually downloaded:



    Snow Leopard update 10.6.4 included an update to 7.6.6 (if installed). You can install it from the above link  even though it says for 10.6.3. It's the same version of QuickTime Player 7.6.6.


    (Only QuickTime Player 7.6.3 or 7.6.6 can be updated to "Pro".)


    A Mac OS X v10.6, OS X Lion, and OS X Mountain Lion-compatible version of QuickTime Player 7 is available for use with older media or with AppleScript-based workflows. QuickTime Player 7 can be used to playback formats such as QTVR, interactive QuickTime Movies, and MIDI files. Also, it supports QuickTime 7 Pro registration codes for access to QuickTime Pro functionality.

    Thanks for the problem solving! Wonderful thought, although it didn't work.

    I was only monitoring this thread in case something came from using ClamXav, so I don't have a lot of time to play with it, but decided to see what was going on for myself.


    I'm almost certain the problem is with the web site. I tried to download Part 5 Session 1 and it was not able to find the file. I suggest you contact them and report that Parts 5 and 6 are not accessible.
