Nod32 quarantine

Are you referring to SC-KeyLog being detected as malware? If so, this is quite normal. It is a keylogger. However it is not malware. It is just something you decided to download and use. Keyloggers are not always malware; however the nature of the programs is always detected by malware scanners as a potential problem. If you are the one that downloaded/installed the program then it is your responsibility to know that it is you that chose to install the program and that it is not a problem.
