I run Secunia PSI to detect outdated programs on my PC that might have vulnerabilities. It is reporting C:\Program Files\Trend Micro\TMIDS\7z.exe, as version 9.20 of 7-zip and states the latest version, 16.x, patches several vulnerabilities. When I attempt to update, I get 7-zip installed as a new program in a new program files folder. Are the 7z.* files in the Trend Micro folder necessary (i.e. can I delete them)? If it is 7-Zip, shouldn't you be updating to a later version? If it's something else, please let me know and I'll report the error to Secunia. Thanks!
