Is battle-net-update.exe a Virus or Malware?
The legitimate file is not a virus. However, malware can mimic the name. If the file is outside the Battle.net folder or lacks a valid signature, scan immediately.
How to Tell if battle-net-update.exe is Legitimate or Malware
- File Location:: Must be in C:\Program Files (x86)\Battle.net\Battle.net Update Agent\Battle.net.Update.exe or C:\Program Files\Battle.net\Battle.net Update Agent\Battle.net.Update.exe. Any other path is suspicious.
