What proof do you have that the official infinite coin wallet is malware? If i can remember correctly Ifinite coin has been around a while and i think we would have seen a bit more information on this if it was true.
(Not that I don't believe you, I fully believe alt coins could be created just to steal BTC)
the 3-coin post in OP asks people to download a update ........... from media fire..
if thise is not evidence enough of scammy practice then what more evidence do you need.
NEVER download anything from file sharing sites. only get them from the official source that has been checked by multiple people first.
I am blocked from the 3-coin post so i was unable to view it, one question i have is that posted (and confirmed) as the creator of Infinite coin or maybe an impersonator? Also i agree if you have Bitcoin on your machine you need to ultra vigiliant of what you download.
my evidences have 2 point:
1. I re-install a clean OS, virus check is OK; then I only run infinitecoin wallet, virus warning.
2. when my friend BTC and LTC are stolen, while somebody is sending some infinitecoins to wallet. but when you begin to investigate, somebody transfer coins away, just like it's his wallet, even you changed password.
