1] Optimize Avast Startup Settings

Avast antivirus often loads faster on a Windows computer, and this can lead to conflicts with other Windows default services. To avoid Avast antivirus slowing down your computer or internet, optimize its startup option to allow other default services to load before it launches. Follow the steps below:

• Open the Avast Free Antivirus software on your computer.
• Click the Menu option at the top right corner of the screen, and select Settings.
• From the left-pane options, select Troubleshooting.
• Ensure that you checkmark the “Delay Avast startup” option.
• After enabling that option, close the window and restart your computer. Avast will then allow the default Windows services to load fully before it launches.

2] Adjust Avast Web Shield Settings

Web Shield is a security component embedded in the Avast software, and it monitors the network activities of a computer. Sometimes, your computer may confuse the Web Shield activity speed with your internet speed, thereby leading to the internet connection significantly slowing down. We advise that you adjust the settings to improve web performance when using Web Shield. Follow the steps outlined below:

• Open your computer’s Avast Free Antivirus software and navigate to Menu > Settings.
• Click on the Protection tab and select Core Shields from the option listed.
• Navigate to the ”Configure shield settings” section and select Web Shield.
• Disable the “Enable HTTPS scanning” option. Note that when disabled, the File Shield still scans all downloaded files from the internet.

3] Disable Avast Background Updates

Automatic updates and installation frequently going on for the Avast antivirus software can cause the computer to be slowing down, particularly when using the internet. However, you can disable the update to improve the performance. Follow the steps below:

• On the Avast Free Antivirus window page, click on Menu and navigate to Settings > Updates.
• Under “Virus definitions are up to date”, click on More options.
• Select “I’ll update them manually”
• If there’s an update available, you’ll be notified to download and install the update at your convenience.

4] Disable Avast Community Participation

As we stated before, your computer may be slowing down because of CPU-hogging features in Avast. One of them is the community participation and data-sharing option. Follow the steps outlined below to disable it:

• Open the Avast Free Antivirus software on your computer and navigate to Menu > Settings.
• In the General tab, click on Personal Privacy.
• Under Improvements, uncheck the two options. This will stop the software from shipping files or contributing to the Avast community.

6] Clear Windows Cache Files

Another solution worthy of trying to fix your computer or internet slowing down is to clear the temporary files in the system file cache. It is regarded as good tech hygiene to make your computer run faster. You can set your computer to delete temporary files that are of no use to your system or program applications. Follow the steps below:

• Press Windows key + I to open Settings, then navigate to System > Storage.
• Scroll down to the Storage sense section and enable the feature.
• Click on “Change how we free up space”.
• Enable the “Delete temporary files that my apps aren’t using” option under Temporary Files.

7] Update Windows and Avast

Windows update helps computers get the latest fixes and security improvements, which can make your computer run faster and more efficiently. Follow the steps outlined below:

• Press the Windows key + I to open the Windows Settings, then navigate to Update & Security.
