This is know by Microsoft I am sure.
In Issue 46 of Windows Secrets Newsletter
(
https://windowssecrets.com/info/) Brian Livingston wrote
an article called Anti-Adware misses most malware.
Quote:
"(Eric) Howes, a well-known researcher among PC security
professionals, collected 20 different anti-adware
applications. He then infected a fresh install of Windows
2000 SP4 and Office 2000 SP3 with several dozen adware
programs in separate stages. Finally, he counted how many
active adware components were removed by each anti-adware
product."
"In the following table, which was reviewed by Howes
himself before its publication here, the Adware Fixed
column represents the percentage of critical components
successfully removed, not just detected, by each product
(higher percentages are better). The False Positives
column shows the number of benign Windows files that were
incorrectly reported by a product as adware (lower
numbers are better):
Product, Adware Fixed, False Pos.
Giant AntiSpyware, 63%, 0
Webroot Spy Sweeper, 48%, 0
Ad-Aware SE Personal, 47%, 0
Pest Patrol, 41%, 10
SpywareStormer, 35%, 0
Intermute SpySubtract Pro, 34%, 0
PC Tools Spyware Doctor, 33%, 0
Spybot Search & Destroy, 33%, 0
McAfee AntiSpyware, 33%, 9
Xblock X-Cleaner Deluxe, 31% 1
XoftSpy, 27%, 3
NoAdware, 24%, 0
Aluria Spyware Eliminator, 23%, 3
OmniQuad AntiSpy, 16%, 1
Spyware COP, 15%, 0
SpyHunter, 15%, 1
SpyKiller 2005, 15%, 2
"
So all that said, Microsoft seem to be aware that not ALL
spy, ad or mal ware is found by Giant AntiSpyware. If
they do anything about it is another story.....
So we will just have to hold our breath in anticipation.
