Independent Antivirus Lab Test Results
Around the world, researchers at independent antivirus testing labs spend their days putting antivirus tools to the test. Some of these labs regularly release public reports on their findings. We follow four such labs closely: AV-Comparatives, MRG-Effitas, SE Labs, and AV-Examination Institute. We also take note of whether vendors have contracted for certification by ICSA Labs and West Declension Labs.
Security companies typically pay for the privilege of existence included in testing. In return, the labs supply them with detailed reports that can help improve their products. The number of labs that include a item vendor serves as a mensurate of significance. In each case, the lab considered the product important enough to examination, and the vendor felt the price was worthwhile. The labs don't necessarily test a vendor'south gratuitous product, but near vendors pack full protection into the gratuitous product, enhancing premium versions with additional features.
We Test Malware Protection
In addition to advisedly perusing results from the independent labs, we besides run our own easily-on malware protection test. We betrayal each antivirus to a collection of malware samples, including a variety of different malware types, and annotation its reaction. Typically, the antivirus will wipe out most of the samples on sight and detect some of the remaining ones when we try to launch them. Nosotros derive a malware blocking score from 0 to x points based on how thoroughly the antivirus protects the test organisation from these samples.
Since we utilize the same samples month later month, the malware-blocking test doesn't measure a product's ability to discover brand-new threats. In a separate test, nosotros attempt to download malware from 100 very new malicious URLs supplied by London-based testing lab MRG-Effitas, typically less than a few days old. Nosotros notation whether the antivirus blocked all access to the URL, wiped out the malicious payload during download, or did nothing.
