Trainers Alter games so that you can cheat, so due to the nature of the cracks Norton could be seeing the alteration as so sort of crack / hack or what ever you would like to call it.
If I'm interpreting your reply correctly, you've applied the hotfix and excluded these games/trainers from SONAR convictions. SONAR no longer detecting them is by design and is the purpose of giving you the option of an exclusion. No need to be alarmed.
As for the trainers crashing, which trainer/game combination exactly is the one crashing the system? The poster above you seems to be using the trainer software "just fine". Perhaps the cause of the crash is something else unique to your system?
Please note the following regarding trainer software from cheathappens.com:
VIRUS WARNING?
Did you receive a VIRUS, TROJAN or
SPYWARE warning from one of the files you downloaded
from our site? Please be aware that we scan all of the
files we upload with multiple antivirus and spyware
applications before posting them on the website. Some
files, such as trainers, can often set off a scanner's
heuristic warnings which may result in them being labeled
a "GENERIC" or "SUSPICIOUS"
trojan or virus. This is simply because of the way trainers
work. They modify another program while it's running
and also listen for keys to be pressed on the computer
so the options can activate. This is exactly what a
real trojan might do
This will scan with 18 different antivirus scanners
and report the findings immediately. If a file is truly
infected, it should set off at least 70% of them. If
the only thing that shows as positive is GENERIC,
SUSPICIOUS or PACKER then the file
is typically clean.
If after scanning, you believe the file is truly infected,
you can use THIS FORM to let
us know and we'll have a closer look at it. If the file
is found to be infected by our scanners then the file
will be promptly removed from the website.

<P>This file is a part of the<EM> TRAINER MAKER KIT</EM>,
a popular program used to create trainers. This file
has been around for many, many years and somewhere along
the way it got labeled as a trojan keylogger. <STRONG>THIS
IS A FALSE READING</STRONG>. Many popular antivirus
applications have removed this false positive from their
signatures, but some still carry it (such as NOD32).
This file <STRONG>IS NOT A TROJAN KEYLOGGER </STRONG>and
is completely safe. It simply listens for keys to be
pressed inside the game so it can activate the options
from the trainer. </P></TD>

In the context of what they are doing, the key hooking/logging appears benign. We recognize this and consequently give our community of users the option to exclude a binary from heuristic convictions by SONAR if they believe the software in question is safe to use.</P><P> </P><P>We mustn't forget, however, that keyhooking/logging features can certainly be abused and compromised by malware. That is one of the reasons why our heuristic technologies use it as part of our secret sauce when determinining is something should be convicted. Thank you for bringing that to our attention. We're investigating this matter. </P><DIV class="message-edit-history"><SPAN class="edit-author">Message Edited by Carlos_Linares on </SPAN><SPAN class="local-date"> 09-11-2009</SPAN><SPAN class="local-time"> 01:02 PM</SPAN></DIV>
