The top 14 antivirus offerings shown here in alphabetical order scored at least 17.5 points out of a possible 18. You can drill down on the full results at The AV-TEST Institute’s website.
How to use these antivirus test results
Keep in mind that these tests were done in a lab environment. Different enterprise systems with different threat models will see different results for each of the products listed below. In other words, don’t expect that a 100% detection rate in the lab means that a product will detect all antivirus threats on your network. One reason is that it can take days for a newly submitted malware sample to make it into any given antivirus product’s database.
What the AV-TEST results show is which Windows antivirus products are consistently the best at the fundamentals of malware detection and have minimal impact on system performance. That makes a good starting point as you evaluate which products work best for your environment.
