Bitdefender is the best choice if you are looking for an anti-virus solution that has high malware detection rates with minimal impact on your system performance, as well as affordable cost. It also has distinct features, including shredders for documents as well as a webcam/microphone blocker that blocks any suspicious requests.
Another key aspect is the ease to use your antivirus. Avast and Bitdefender both have a relatively straightforward interface, however Bitdefender is a bit more complicated when it involves running scans. It took us longer to locate the settings we needed to set up an entire scan or a boot-time scan was somewhat difficult.
As for support, Bitdefender’s customer support is far superior to Avast’s. Its customer support phone line is able to speak a wide range of languages, and its knowledge base is extensive. Avast however, restricts its contact options to customers who pay and relies heavily on its forums and knowledge base.
