Most false alarms will probably fall into the first two levels most of the time. Such cases are likely to be seen much less frequently in a false alarm test done at a specific time, as such files are usually either whitelisted or would be noticed and fixed very fast. Probably several hundreds of thousands or millions of users Probably several tens of thousands (or more) of users

Initial distribution of such files was probably much higher, but current usage on actual systems is lower (despite its presence), that is why also well-known software may now affect / have only a prevalence of some hundreds or thousands of users. Individual cases, old or rarely used files, unknown prevalence The prevalence is given in five categories and labeled with the following colors: Files which according to several telemetry sources had zero prevalence have been provided to the vendors in order to fix them, but have also been removed from the set and were not counted as false alarms. prevalence вЂњlevel 1вЂќ and a valid digital signature is upgraded to the next level (e.g. Files which were digitally signed are considered more important. In order to give more information to the users about the false alarms, we try to rate the prevalence of the false alarms.

VIPRE Internet Security Pro 9.3 Build: 9.3.6.3 It doesnвЂ™t mean the product with 5 FPs doesnвЂ™t have more than 5 FPs globally, but it is the relative number that is important. 30 FPs and another only 5, it is likely that the first product is more prone to FPs than the other. If, when using such a set, one product has e.g. What can be done, and is reasonable, is to create and use a set of clean files which is independently collected. There is no complete collection of all legitimate files that exist, and so no вЂњultimateвЂќ test of FPs can be done.

False Positives Tests measure which programs do best in this respect. No product is immune from false positives (FPs), but some produce more than others. One aspect of reliability is the ability to recognize clean files as such, and not to produce false alarms (false positives). In AV testing, it is important to measure not only detection capabilities but also reliability. This report is an appendix to the Malware Protection Test March 2017 listing details about the discovered False Alarms.
