Bitdefender is the clear winner if you are looking for an anti-virus solution that has excellent malware detection rates and minimal impact on the performance of your system as well as reasonable cost. It also offers some distinct features like a file shredder and microphone and webcam protection which denies any suspicious requests to your microphone or camera.
Another important aspect is how simple it is to use your antivirus. Avast and Bitdefender both have a simple interface, however Bitdefender is a bit more difficult when it involves running scans. It took us a while to find the settings, and it was difficult to set up a full or boot-time scan.
In terms of support, Bitdefender’s customer support is superior to Avast’s. Its customer support phone line is able to speak a wide range of languages, and its knowledge base is vast. Avast, however, limits its contact options to customers who pay and relies heavily on its knowledge base and forums.
