I'm sure you have ran into this issue before: it's known that VirusScan removes some antivirus softwares during its installation. KB article #72251 provides a list of the supported products to be removed.
But what are the options when the currently implemented AV product is not listed there? Are there alternatives to remove those during VirusScan installation? Running a command line with the product deployment task, maybe? Please share your experiences and thoughts.
