Doing MD5 checksum check on cisco FMC install file

 A client AV detected as malware so I wanted to confirm the hash 

certutil is built in so I used that but there are some free GUI tools

certutil -hashfile Cisco_Secure_FW_Mgmt_Center_Upgrade-7.2.9-44.sh.REL.tar MD5 | find /v "hash"

Compare the result to the MD5 hash on cisco.com downloads section. If you hover the version the MD5 and SHA1 hashes will be there to copy.
