This anti-malware/anti-virus scanner offers real-time and manual protection against all types of hazards. Its real-time scan feature uses a cloud database to remain up-to-date and also guards against emerging threats.

This software detects unwanted applications and blocks them. Some programs come bundled with other programs and when you install them, the unwanted ones get installed as well without your knowledge. If you use the browser extension of Avira, it will detect harmful websites and block advertisements as well.
