Some have asked me about certain aspects of LAT, and I have decided to 
send one public message insead of multiple messages via Email.

1. I started LAT because of the hype in advertizing. I bought two less 
than adequate anti-virus programs, and I thought other users might like to 
see some fair and unbiased reports on anti-viral software before they buy. 
I have no vested interest in any of these companies, and I am not paid to 
compile this report.

2. LAT is an acronym it means "Lambdin's Accuracy Tests"

3. The chart is scanner certification pure an simple. I have the scanners 
passively  scan for viruses on the hard drive.

4. VCheck from Victor Charlie only detects the 60 or 70 most common 
viruses, and the authors of Victor Charlie "Alan Dawson, and John DeHaven" 
request that VCheck not be included in scanner certifications such as the 
chart in LAT.

5. The testing of scanners and the recommendations of generic virus 
detection software is two different tests.

First I extract a subset of my viruses to diskette. This subset contains 
specimens from all types of viruses.
 
Direct infectors, viruses that run as TSR, companion infectors, stealth 
viruses, polymorphic, boot sector infectors, etc.
 
Then I install this generic virus detection software to another diskette, 
then go into my CMOS and deactivate my hard drive temporarily,

I run the generic detection software, then run a virus, run a few small 
files so these files will be infected, then run this generic virus 
detection software If it detects the virus. I go through the same steps 
with another virus. It usually takes a few hours to fully evaluate one of 
these products. After the software has prooven that it can really detect 
new or unkmown viruses without relying on signature scanning, I put it in 
the list of generic virus detection software that I recommend.

Since there are several different ways to detect viruses with generic 
methods, It isn't easy to use a % scale like I use for the scanner 
certifications.
 
1. Integrity checking as used in Integrity Master, Untouchable, and Victor 
Charlie.
 
2. TSRs like PC-Rx and PC-cillin that looks for virus like activities.
 
Hooked interrupts
Access to the boot sector
access to the partition table
programs loading as TSR
tampering with executable files
and more.

3. trying to get infected on purpose like Victor Charlie
