Overview

Signed By: Tencent Technology(Shenzhen) Company Limited
Status: Valid

The signature on t4.dll is reported as valid. A valid signature helps confirm publisher identity, but it does not automatically make the file safe if the installer was bundled, abused, or downloaded from an untrusted source.

ThreatInfo has observed t4.dll in the locations listed above. Files found in temporary folders, user profile folders, startup locations, or unusual application directories should be reviewed more carefully than files installed under a known program directory.

File Names:
