Probably already been said but be wary of installing wallets for new alt-currencies, I've heard of at least two wallets with keyloggers. Also make sure to download from official websites and not random links posted up on the forum.
Would you mind sharing a little bit details? I have tried to search with Google but got no results.
The Tradercoin wallet contained a keylogger/trojan:
https://bitcointalk.org/index.php?topic=317201.0"Carefull this newly released coin seems to contain a virus or keylogger -
It creates the a fake crss file in the C:\Users\acer\AppData\Local\Temp\crss.exe
then creates the following registry directory too:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\MSConfig\startupreg\MXsound
The process is then found in msconfig under the name MXsound (crss.exe)"
