I'm new into crypto currency and was wondering which wallet I should use in terms of security.
I prefer desktop wallet then online, but make sure you have some anti-virus and scan if it has trojan...
Anti Virus does not guarantee that you do not get infected by trojan or other virus. There are plenty of fully undetectable viruses which means they cannot be detected. The best method is to verify and build the wallet yourself from source, I wouldn't download the wallet if its not open sourced.
