First of all, there is no virus in GT4T, the file reported is actually a rename of autohotkey.exe. GT4T has been sold overseas since 2009, there are occasional problems with false positives by antivirus, but after I contacted the antivirus manufacturer, I was able to solve it, but not with 360.

For 360, false positives are their strategy to reinforce users' reliance on 360. Individuals and small developers alike suffer from 360 false positives. See this post on Zhihu for details.

If you can't use GT4T after adding trust, please uninstall the 360 security products. If you are apprehensive about not having an antivirus, you can install a Huo rong.
