Trend micro just updated today and required a restart. But even before the restart, I received the above error message at the bottom of some web pages served by a web server on my local machine. It seems to only appear when the CGI mechanism is invoked. The programming language of the CGI is perl.

My web research on this topic reveals that TM is the problem as it reacts to certain executables. But in the case of a webserver, which one? The perl.exe? The cgi code? The web server (apache httpd). How can I fix this problem? Thanks :)

Oops...almost forgot: I tried the hotfix (Ti_110_win_en_amsp50_UMH_hfb2.5.2017.exe). It does not install because I have "an incompatible version" of the product.

Here go:  going to answer my own question.  I added the perl.exe to the exeptions list.  Didn't like doing it, but it is what made the difference.

Hi @BP, sorry that the Hotfix didn't work for you. But great to hear that you fixed the problem!

I assume that you are using Maximum Security 8.0 or Maximum Security 10.0 so that when you were trying the Hotfix, and "an incompatible version" message appeared. Could you upgrade your Maximum Security to the latest version (ver 11.0),  then follow the steps in support page below to apply the hotfix again?
  1. Upgrading Trend Micro Security to the latest version
  2. [Hotfix] "[0x7FFEB62770E3] ANOMALY" error message appears when running commands in Command Prompt
Please let us know if the above procedures work for you. Thanks.
