Is avira.exe a Virus or Malware?

How to Tell if avira.exe is Legitimate or Malware
- File Location: Must be in
C:\Program Files\Avira\Security\avira.exe or within the Avira installation folder. Any avira.exe elsewhere is suspicious.

Red Flags: If avira.exe is located in unusual folders (like Temp, AppData, or System32), runs when Avira isn't active, has no digital signature, or uses excessive resources constantly, scan your system with antivirus software immediately.
