If, however, you’re looking for an antivirus program that has high malware detection rates with minimal impact on system performance, and a reasonable price Then Bitdefender is the clear winner. It also has unique features, like a shredder for files and a protection for microphones and webcams that block any suspicious requests.
Another important aspect is how easy it is to use your antivirus. Avast and Bitdefender both have a fairly basic interface, but Bitdefender is a bit more cumbersome when it runs scans. It took us a while to locate the settings and it was difficult to set up a full or boot-time scan.
In terms of customer support, Bitdefender’s is far superior to Avast’s. Its knowledge base and phone support are both extensive. Avast however, does limit its contact options to paid customers and heavily relies on its forums and knowledge base.
