I want to stop Avira Anti Virus services in services.msc. Stop service is disabled for me. I am administrator of the computer. I installed it from the same account from which I am trying to stop.

If I try to kill the process from Task Manager, it says Access Denied. What's up with this antivirus?

I need to stop it as it is causing problems in my software development.

You can disble the protection against this in Avira's security settings. – poepje Jun 15 '15 at 20:14

You probably need to uninstall it, or disable it from the control panel / options that come with the A/V. Many viruses try to do the same thing you're doing (disabling the service) so that they can turn off the antivirus, so many A/V products mark their services as critical so that that can't happen.

If you have trouble uninstalling the antivirus, you could try using Revo Uninstaller. – Suchipi Oct 19 '12 at 19:44

Note to reviewers: While the answer should contain a brief description of the software, Process Hacker is not spam (…). – bwDraco Dec 31 '15 at 7:28
