Actually, it's not recomended to use even several antispyware programs on
one computer. The problem is connected with the way how antispyware and
antiviruses work. Some of them hook (Kaspersky for sure) SDT (service
descriptor table), and if another AV is installed, which also hooks SDT then
BSOD might happen. Because, at the moment of modification of handler address
in SDT the system might trigger dispatch call, and the call will go nowhere,
because there is no syncronization mechanism for SDT - in this case it will
act as shared resource. The same applies to several firewalls - in case of
hooking TDI provider.
Also, take into consideration a perfomace factor. In case of several AV
installed on a system, the system will be working slowly. Those handles
which are installed by AV software need CPU time to execute.
P.S. I do not recommend you to use Kaspersky products. Read these links:
