Those kinds of comparative testing results will vary
depending on a variety of factors to include but not limited to who conducted the testing, what they were testing for (type of threats, attack vectors, exploits), what versions of anti-virus software was tested, what type of scanning engine was used, and the ability to clean or repair. There are no universally predefined set of standards
or criteria for testing which means each test will yield different results. As such, you need to look for detailed information about how the tests were conducted, the procedures used, and data results.
You ask a common question for which you will receive varying opinions and recommendations.
