I am in the middle of preparing to help out a friend with some consulting help for migrating from Symantec Endpoint Protection 11 (SEP11) to McAfee Total Protection for Endpoint on their corporate endpoints. As you may know, Symantec has the only corporate AV solution in the industry WITHOUT a centrally managed/controlled UNINSTALL function.
Anyway, so in researching how I need to accomplish this, I found a good list on MSDN for all of the standard installer command-line options for Windows installer (i.e. msiexec.exe options, MSI package commands). Thanks Microsoft, at least you are helping to document how to clean up after lame vendors like Symantec.
In Symantec’s defense, they do have knowledgebase articles for how to manually uninstall SEP here and MSI options here. However, McAfee ePO has a central way to do this, as does Kaspersky, Trend Micro, Sophos, you get the picture.
