How to Stop Avast From Running in the Background in 2024?

Don't want to uninstall Avast or disable the Shields. Stop Avast or any antivirus tool from running in the background.

If you’re using Avast antivirus on your Windows computer, you might want to stop it from running quietly in the background. Even though Avast is known for being good at catching viruses without slowing down your computer too much, some people might face issues like Avast using a high CPU.

If you’re dealing with Avast causing problems, you might want to stop it from starting up when you turn on your computer or running in the background. It can be a bit tricky because even if you try to turn it off completely, parts of it might still be running.

In this article, we’ll talk about why antivirus programs like Avast run in the background and how you can stop Avast from running when your computer starts up.

Why does Avast Antivirus Run in the Background?

Antivirus programs, like Avast, run persistently in the background as a proactive defense against malware threats. This continuous operation ensures that the antivirus remains active even in the face of potential attacks, safeguarding your computer. These programs vigilantly monitor incoming and outgoing traffic, promptly alerting you to any suspicious activities.

While turning off Avast might seem like an option, doing so leaves your PC vulnerable to malware that can disable antivirus protection. Some users express dissatisfaction with background-running programs, opting to switch to more self-contained platforms like Linux or Apple, which are perceived as inherently safer.

For those contemplating disabling Avast, it involves a technical process of deactivating the defense module, driver, service, and shields. However, this approach raises questions about the necessity of such actions. Ultimately, uninstalling Avast emerges as a simpler solution for those looking to cease its background operations on a Windows PC.
