It was some kind of virus,deleted it
How did you 'delete' the virus ? Did you check whether it was running in a seperate process or injected ?
Did you use some anti-malware tool to scan for malware/root-kits ? If so, which program did you use ?
Are you COMPLETELY sure that there is no other malware on your computer left ? If you aren't 100% sure, you should rather reinstall your OS before storing sensitive information (e.g. private keys) on your computer again.
