Bad Checksum

[computer_user]

Hi,

I don't know whether or not this would be new or undetected malware but I ran an update this morning and got something peculiar. What does "Bad checksum" mean? It's in the Grail update. Although each detection rule is marked in green there is an X next to them. Usually, I run updates, if Spybot doesn't have anything new to install it will say "No new updates found", so I wonder what this is about.

"Bad checksum" indicates that the download did not complete properly (the MD5 hash value did not match what was expected). See:
Why do I receive the message "update is forbidden" / "bad checksum!!!"?
