To whom it may concern, Thanks for the help from Edwin, kgd and guenther, I have solved the problem with wildcards, such as *, ??, {n}, {n-}, {-n}, etc, in ClamAV's signatures. But there is still a problem. When I tried to build a signature with the wildcard of |, I still didn't succeed. The signature of mine is like this:
Worm.Yawen (Clam)=(6161|6262) I want to use this signature to match "aa" or "bb". It is reported a Malformed database ERROR: Malformed database. Do you have any comments on this issue? Thanks.
