I don't see that with clamav-0.75.1. Personally, I'm intrigued by the fact that the first two characters are not required, and neither are the last 26. It matches on just 38 characters: [EMAIL PROTECTED](P^)7CC)7}$EICAR_STANDA (with _ replaced by -) Interestingly, there's also a second signature (Trivial.Eicar.122) that adds a few more characters (RD-ANTIV) on to the end. Not sure what the purpose of that is.... For completeness, the malware md5 signature requires exactly 68 bytes, which might be what you were seeing?
