Bitdefender is the clear winner if you are looking for an anti-virus solution with high rate of detection of malware and has minimal impact on performance of your system in addition to affordable cost. It also has some distinctive features, like a shredder for files as well as a webcam/microphone blocker that blocks any suspicious requests.
Another crucial aspect is how easy it is to use your antivirus. Both Avast and Bitdefender are fairly straightforward to navigate, but we discovered that Bitdefender was a little more difficult when it came to running scans. It took us a while to find the settings, and it was difficult to set up a full or boot-time scan.
Bitdefender’s support is superior to Avast. The phone support is available in a wide range of languages and its knowledge base is vast. Avast, on the other the other hand, limits its contact options to paying customers and relies on its knowledge base and forums.
