In the past few hours a lot of Contact Form 7 users have reported that their security tools provided by Avast Software have given a security alert about Contact Form 7. In particular, the alert says it has found a Trojan Horse in one of the script files in the Contact Form 7 package.
I have confirmed no such malware exists in Contact Form 7, so I believe that it is probably a false alarm. So far we haven’t received any information from Avast about this case.
I’ll update this post when there is new information.
