What the... Winamp uninstaller infected with a worm?

I downloaded Winamp about a week ago, from the offical website, just to try it out to see if I could use it as my main media player.
It installed fine, worked great, but wasn't to my taste.
So about 30 mins ago I was going through my ad/remove programs list, when I saw it there. As I wasn't going to use it again, I decided to uninstall it...
I clicked Uninstall, and basically all hell broke lose.

Comodo Defence+ started going crazy, saying "UninstWA.exe" was trying to launch "Au_.exe", so I looked it up on google and this Au_.exe looks like spyware/adware... so I blocked it. Then it came up again, saying that Bu_.exe wasn't to launch, then Cu_.exe and it kept going on and on....

I then looked on my desktop, to find a two weird looking files which is in the screenshot below.

I blocked all of them. Then Kaspersky started going crazy, and detected the Winamp uninstaller as a W32 Worm!!!

"detected: riskware Worm.P2P.generic Running process: C:\Program Files\Winamp\UninstWA.exe".

I tried to quarantine it, but it failed.

Here are some screenshots of the event... Any idea's what the hell just happened?

The second screenshot is the Comodo Defence+ log...

I think it triggers a survey, I never pay attention to the surveys.

 

Go with Online Armor......Comodo is way too touchy.

 

Uninstaller uses NSIS, and it's a false positive. It's pretty common on the Winamp forums.
