We eventually had to download a Trend Micro permissions fix, then reinstall.
However, we just had another one where the same happened but the permissions fixer left the computer unable to access the internet, although it can see the local network. No-one else on the network has internet issues. We have tried every troubleshooting step suggested by Trend's help and microsoft. Nothing worked. Trend has well and truly cancelled that PC! Whoever put this program update together wants shooting. Caused me so many issues and lost time. We now have our IT services partners on it and they are also struggling to reverse whatever Trend has done to this system. I don't think we will be staying with Trend once they expire, after this experience.

Hi,

We have staff using their computers as users, not administrators (as is good practice for security). They have Trend Maximum Security on theri PCs. In the last week or so it has been popping up prompts to install a new program version. If the user accepts the prompt, it removes Trend Max Security but does not install the updated version or prompt for anything else.
We had this once before, and I only noticed in doing something else that some users appeared to have no active Trend installation when I knew they were licensed.
This seems like quite a serious problem. Shouldn't it at least prompt for administrator permissions before just removing the software on a standard user account?
If there is something we need to do with the configuration to stop this happening, I'd be grateful to know what that is.

Thanks
