Guys, I'm sure that all these affiliate programs is detected by AV as adware/trojans - nothing new - that's why some people don't want work with them.
I can make small review of pay-per-install programs here, maybe it will be interesting for someone.
1. ZangoCash ($0.40 per US install and more)
(+) Paying very well, a lot of free content
(-) Not giving clean exe, only with warning, you can't place bundle to software directories
2. VombaCash ($0.45 per US install)
(+) Also paying well and stats is OK, small shave, good amount of content
(-) Not giving exe at all
3. Waverevenue($0.40 per US install)
(+) They giving clean exe
(-) Unreal shave!!! It was always with project maded by these guys, if you remember TeddyCash and MatCash - it's same sh*t
4. IframeCash and tons of similiar(all programs where you can find IFRAME word

) around $0.10 per US install )
(+) No
(-) It's fully illegal programs!!! They using exploits to install exe files - not recommend at all because it's against law, crazy shave
5. Theinstalls($0.15 per US install, if you can make more then 10K installs per day - contact for special rates, they made me $0.18 per install

) )
(+) They giving exe, weekly payments, also have reseller program
(-) Shave around 10% - but it's not critical
6. AdwareDollars
(+) Giving clean exe, no shave at all. You get paid for sales, not for installs, but I getting average $0.22-$0.28 per US install from them
(-) It's very new program, sometimes it have some bugs in interface - but I think it just because it very new and seems like still in pre-release
Two latest programs offer you reselling ability, it's means that they give you scripts, consulting and special rates and you'll be able to start own business, your own domain, affiliates base etc. e.g. white label solutions.
Everything depends on how you gaining installs.
If you have just high-traffic web-site - better choose is sure Zango, if bundling(like described in "How to make $100 per day" article) - now one and only programs which giving clean exe without warning and paying good is Theinstalls and AdwareDollars.
I'm working for years in Pay-Per-Install business, a lot of companies starts and close after few months. Now hard times for this industry, but I think we all still have ability to earn $xx,xxx amount with them

Good Luck to all in New Year!!!
