Can't log into T3200M router - " uses an invalid security certificate" self-signed

This is a new one - when I try to log into my T3200M router I get security warnings like " uses an invalid security certificate" because it's "self-signed." (that's on FF) and with Chrome it's: "Attackers might be trying to steal your information from (for example, passwords, messages, or credit cards)." Chrome also says: "This server could not prove that it is; its security certificate is not trusted by your computer's operating system. This may be caused by a misconfiguration or an attacker intercepting your connection." The reason I was trying to log in is because someone new was having problems connecting to wifi. Is it possible this new person has malware? Thanks, B

Most browsers will now give you some form of error related to self-signed certificates. In this case it should be safe to proceed.
