Trojan:W32/Packes is a detection name temporarily assigned to certain packed/compressed malicious programs that our unpacking engine cannot yet handle. When the unpacker code is created for that particular sample or file compressor, the malware will be renamed.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
More information on scanning and removal options available in your F-Secure product can be found in the Help Center.
