I had the following running and all working fine for about 6months on my PC,
before I switch to Linux:
AVAST (Anti-Virus, on-demand)
Spybot
Spyblaster
Spyguard
Adaware
AVG Anti-Spyware (Free Edition only)
WinPatrol (Not really spyware)

Hi,
Generally is very not recommended to use more then 1 antivirus at the same
time on system. That situation can cause completely unpredictable effects -
blue screens, undetected viruses, limited functionality of AVs etc.. This is
the reason why most of AV have routine to detect other antiviruses.

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:

Remove AVG and *ONLY* use Kaspersky.
As others have noted, it is contraindicated to have two fully installed anti
virus
applications on any given PC performing both "On Access" and "On Demand"
scanning.
You can however have ONE fully installed anti virus application performing both
"On Access"
and "On Demand" scanning and multiple other "On Demand" only scanners.
