Hi Conrad. All I can say is that RMS company decision to remove this feature is not a good one for many admins out there. The fact is that sometimes we need to support people without them knowing that somebody is watching. Also, it may be helpful in many other situations.
As far as your company talking to Antivirus Analytics - it's quite an ambiguous assertion. You guys probably talked to Dr Web and Kaspersky. Since AVG and Symantec never, never reacted to RMS as a virus. Instead of proving your point to those companies, you decided to give up and remove the feature. This is a SHAME, to say the least.
As far as I'm concerned, version 18.104.22.168 is good enough and supports Hiding the icon. Neither of good antivirus programs ever gave me a trouble about RMS. So yours and your company excuses are lame.
