These are where all the leftovers are located and unless you delete them and the
relative registry entries, you are not likely to successfully uninstall Symantec AntiVirus. The problem is these entries are hard to pinpoint and you will properly risk a danger of crashing your pc as a result of messing with the registry. I did not want it so I turned for a help. A small application named Best Uninstall Tool came as my final solution, with its force uninstall method. The advantage is, when you indicate a specific file/folder to Best Uninstall Tool, it not only deletes the file/folder, but also scans and takes out all relevant registry information, which is very effective to uninstall Symantec Antivirus as well as other Symantec software like Norton security
