Step 2: Adjust Avast Web Shield Settings

The Web Shield feature, designed to monitor network activity, might inadvertently slow down your connection. Here’s how to optimize it:

  • Access the Avast Free Antivirus software and navigate to Menu > Settings.
  • Select the Protection tab, then click on Core Shields.
  • Go to “ Configure shield settings ” and select Web Shield.

  • Uncheck the options under Improvements to stop unnecessary file sharing.

Pro Tip: Disabling these features still keeps your antivirus effective, as core protection remains active.

Step 5: Clear Windows Cache Files

Clearing cache files can significantly boost performance by freeing up storage. Here’s how to do it:

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