I'm personally running version 4.92 on several Windows 7 and 10 PCs and never had issue, however one of the users send us the following message via Contact Us page of our website
attempted to upgrade TeraTerm to v4.92 and our Malware protection blocked it stating it contained a Trojan.
Malware Name: Trojan:Win32/Varpes.M!cl
This was detected by MS System Center Endpoint Protection.
Tera Term project team will need to investigate this further .
In relation to this it is probably time to start thinking about digitally signing Tera Term executable files. This will help to get rid of numerous popups about' Unknown publisher' at file execution and ensure users that the files are genuine. I've started digitally signing LogMeTT executables 2 years ago. The certificate costs about 100$ per year. I'm not suggesting Tera Term project team to pay for it out of their pocket like I do, but they could revisit their not-taking-donations policy to address this and get the cert.
