How effective is AV?

To see how effective AV engines are at detecting threats some malware samples were sent to Virustotal for analysis.

Samples used were binaries which would end up on victim's computer by exploiting vulnerabilities in web browsers or addons/controls associated with browsers.

Upto %65 of the submitted executables were obtained from fall of last year to spring of this year and checked by AV this month. Others are mainly from this summer.
