The tests carried out by the AV-Comparatives and AV-Test research
centers have their shortcomings, one of which is that the antivirus
software capabilities are checked against collections of relatively old
files (gathered over the preceding six months). Furthermore, it is the
results of on-demand scans that are analyzed, whereas the real-life
situation of a user receiving malicious files by downloading them from
the Internet or as an attachment in an email would provide a more
realistic setting for real-time antivirus scans.
Specialists from the UK magazine PC Pro have tried to overcome these
problems by only using samples of malicious code detected over the
preceding two weeks and sending traffic via servers at the company
MessageLabs. MessageLabs is one of the largest providers of filtration
services for different types of traffic and the collection of malicious
code provided by the company reflects the current situation on the
network at the time of testing. During testing the specialists from PC
Pro imitated everyday user actions such as downloading mail with
infected attachments. They also created a script that simulated the
downloading of infected files from the Internet. This type of test is
closer to real-life conditions and, as can be seen, the detection level
is not as high as for the on-demand scans.
Even under these more demanding test conditions Kaspersky Anti-Virus
still achieved the best results.
