What is Avastvboxsvc.exe & Should I Remove it?

From the name, avastvboxsvc.exe belongs to the Avast family so it has to do with the security of your device.

Windows has built-in antivirus but might not be as thorough as other third-party security software. On the downside, these additional antiviruses consume a chunk of your system resources and can significantly slow down your PC.

For instance, the avastvboxsvc.exe works in the background to monitor apps’ behaviour and quarantines them if they’re found of suspicious activities. While this is great, on the downside, it uses a lot of memory and can interfere with other tasks.

So yes, an overzealous antivirus is good for your device’s protection but not so forgiving on the memory footprint among other system resources. Nevertheless, while it is an important file, it is not essential for running Windows so you can remove it.

How do I remove avastvboxsvc.exe?

1. Limit CPU usage

1. Click on the Start Menu icon, type Task Manager in the search bar, and click Open.
2. Navigate to the Details tab.
3. Right-click avastvboxsvc.exe, and select Set affinity.
4. Now uncheck all CPUs if you don’t want the avastvboxsvc.exe using any processor.

Limiting CPU usage may help address the resource usage issue but on the downside, there may be a system instability issue.

2. Turn off self protection

2. Select General on the left of Avast Antivirus.
3. Click Troubleshooting, and scroll down to the bottom of that tab.

5. Select the Troubleshooting tab shown directly below.
   
6. Finally, deselect the Enable Avast self-defense module option if it’s selected.

From the options above, it appears each solution has its own downside if you’re trying to get rid of avastvboxsvc.exe from your system.

The only viable option seems to be uninstalling the parent program. If Avast has been your dedicated antivirus program, you’ll have to look into other antivirus programs.

Offline antiviruses are a good alternative as they are known to consume less system resources compared to their counterparts. They also have reduced background activity unlike those that run in the background and are continuously scanning for threats.

After all, Avast has been known to have some issues. Avast is a CPU hogger and sometimes, it can keep detecting your network as a new one each time.

Other times, Avast can slow down your internet so in light of all these problems, it may be time to consider another reliable and comprehensive security software.
