Symantec isn't the only one in this fight. But they are the most outspoken regarding microsofts decisions and i feel for them, and the other companies, who for years have provided a needed product and now are having to watch as microsoft is playing games to ensure the public uses its built in security.
Your views of symantec are justified, but you may want to consider that the problem you encountered trying to uninstall symantec in her notebook, could also have been windows in itself causing the uninstall to fail. Who knows there could have been a corrupt file in there.
