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.
Detailed instructions for F-Secure security products are available in the documentation found in the Downloads section of our Home - Global site.
