I'll put a dozen or more on there if that's what it takes.
I want to load his computer up with as many free programs that I possibly can that wont conflict with each other. And I've installed Malwarebytes as a stand-alone to scan and fix with. I've installed Microsoft Security Essentials for the real-time virus/spyware protection. I'm fixing my friends computer again because due to his unsafe surfing habits, he got it wrecked up with malware again and it required a reinstallation of XP-Pro.
