Will uninstalling Avast Antivirus affect my computer’s security?

Yes, uninstalling Avast Antivirus will remove the protective features that guard your system against malware, viruses, and other security threats. After removing Avast, your computer will be vulnerable until you either install another antivirus solution or re-enable Windows Defender, which provides basic protection.

It is advisable to have another antivirus program ready to install before uninstalling Avast. This ensures that your system remains protected against threats. Alternatively, you can enable Windows Defender immediately after uninstalling Avast for basic security coverage.
