Avast Free Antivirus 2017 - Review 2017 - PCMag Middle East Feb 23, 2017 · Webroot SecureAnywhere AntiVirus ($18.99 at Webroot) detected more, 100 percent, but imperfect blocking of some samples took it down to 9.7 points. On the other hand, Avast's score is bracketed by Kaspersky Free above and Bitdefender below. All three did very well in lab tests but not so well in my hands-on tests.
