Sophos Antivirus Is Not Running

Applies to Sophos Home for Windows. What's happening. Sophos Home detects another Antivirus software (or leftovers of it) is installed on the system and shows the following message: Third party antivirus Running two antivirus programs can reduce your security. For maximum protection, we suggest you uninstall antivirus name Antivirus. Why Sophos Anti-Virus is not working on Mac running MacOS 10.13? Apple has released a new security mechanism called Secure Kernel Extension Loading (SKEL) in MacOS 10.13. I have the same version of Sophos on both computers. I'm not sure what 'Sophos Home' is that you're referring to. Both machines have 'Sophos Anti Virus Home Edition version 9.4.0' installed. Both machines have 'Threat detection engine 3.61.0' and 'Threat data 5.21.' The iMac works, the Mini doesn't.

You can see applications that you have allowed to run on your computers.

On the Settings > Allowed Applications page you can see applications that you have allowed to run on your endpoint computers.

The page shows where the application was originally detected (if applicable) and how it was allowed.

About allowed applications

Our software detects threats that are previously unknown. However, it may sometimes identify an application as a threat, even though you know that it’s safe. When this happens, you can “allow” the application. This does as follows:

  • Prevents this detection from happening again.
  • Restores all copies that have been cleaned up (removed from computers).

Alternatively, you can allow an application in advance, so that it won't be detected when you install it for users.

Warning Think carefully before you allow applications because it reduces your protection.
Note If an option is locked global settings have been applied by your partner or Enterprise administrator. You can still stop detecting applications, exploits and ransomware by going to the events list.

Allow an application that's been detected

Only allow an application if you know it's safe. For help deciding, see How to investigate and resolve a potential False Positive or Incorrect Detection.

To allow an application that Sophos has detected and removed, do as follows.

Note that:

Sophos
  • This allows the application for all computers and users.
  • This allows the application to start, but we’ll still check it for threats, exploits and malicious behavior when it's running.
Security
  1. Go to the Computers or Servers page, depending on where the application was detected.
  2. Find the computer where the detection happened and click on it to view its details.
  3. On the Events tab, find the detection event and click Details.
  4. In the Event details dialog, look under Allow this application.
  5. Select the method of allowing the application:
    • Certificate: This is recommended. It also allows other applications with the same certificate.
    • SHA-256: This allows this version of the application. However, if the application is updated, it could be detected again.
    • Path: This allows the application as long as it's installed in the path (location) shown. You can edit the path (now or later) and you can use variables if the application is installed in different locations on different computers.
  6. Click Allow.

Edit the path for an allowed application

You can change the path that you specified when you allowed an application.
