No, it will be the "blue screen of death" if they are good anti virus programs.

prepare for some frustrating internet surfing.
Go for it........but you had better stand back !
You should use one

Make it Spy Sweeper , they have a new Anti-Virus
It's generally not recommended to install two anti-virus softwares at the same time, as many of them interact with the operating system at a low-level, overriding system calls that will conflict with each other. Most software installation instructions warn you about this, but you will have to consult your particular software's instructions.

The best anti-virus software you can have is common sense. I don't use any anti-virus software, and I've never had a problem. Of course, I also don't use Windows, or other proprietary technologies from Microsoft that are designed to be insecure and hand over your computer to virus writers. I would suggest you look into other operating systems like Ubuntu Linux if you are worried about viruses.
One might just shut the other one down, or having both installed may make your system crash.
Yes it would. However if you believe in what the bible tells you then virus-kind will have to drink twice the ammount of jesus blood for forgiveness !!!!
