First of all, you are off topic for where you posted. This forum is for the former subscription product, Windows Live OneCare.
There is no legitimate security product called Internet Security Essentials. There are many, many scam security programs out there that pretend to be legitimate. You've apparently been duped by one of them.
There is a legitimate program called Microsoft Security Essentials, but there is no trial version. it is a full security product and it is free.
