Most Antivirus Products Improve in Latest AV-Test Report
QUOTE: German antivirus testing lab AV-Test.org runs whole-product, dynamic tests on antivirus products constantly and releases a certification report every two months. In this year's March/April test, AhnLab and ESET failed to achieve certification. Both managed to improve for the May/June test; nobody failed this time. ZoneAlarm made an impressive debut, just one point besides top scorer Bitdefender.
