Thanks tashi for your reply.
I have Windows XP running on Dell Optiplex 745.
I used to have the following security programs installed on my computer.
1) McAfee AntiVirus
2) McAfee Firewall
3) Spybot S&D with Teatimer
4) SpywareGuard
5) SpywareBlaster
6) MBAM
7) SuperAntispyware
Because my computer was infected with spywares recently, so I have my friend to reinstall Windows XP, but he installed MSE for me as well.
My question: Would there be any conflict if I want to install all of the above 7 programs with MSE already installed?
Thanks.
