1. Check installation integrity.
Open Avast → Settings → Troubleshooting → Repair App. After the repair completes, restart your computer.
2. Reinstall Avast.
If the issue persists, completely uninstall Avast using the steps above, then download and install the latest version. This often fixes component errors.
3. Check for conflicts.
Other antivirus or firewall programs may interfere with Avast. Temporarily disable them and test whether VPN or scanning features start working again.
4. Update your software.
Make sure Avast and its virus definitions are fully updated. Outdated modules often cause malfunctioning features.
5. Contact support.
If the issue continues, email [email protected] with your Avast version and error details.
If functions disappeared, became paid, or the system became unstable after an update, file a complaint on Xolvie — your feedback helps prompt action from the company and protect other users.
