AV Comparatives only check the antivirus solutions against 6 moth old samples, so they are not really out in the wild.
The VirusTotal Results have been gathered from many support forums where the posters have are talking about a new sample, not 6 moths old ones. Though I have been at the receiving end from Kaspersky who say that as VT uses a very old version of Kaspersky's antivirus products, the detection might not be accurate. I agree with them, but that's the best way we have got. I am in short collecting the VT results for all new threats received and analyzed from malicious urls and exploits that have been submitted in the forums. I lay no faith in detection of old samples as they are rarely out in the wild.
