The main problem I have with Virex is that you have to be logged into an admin account for it to automatically update the virus definitions etc., because it only allows you to write-in a password and not a username (because it assumes you're already logged into an admin account). The advice I've been given is that you should always use a standard account for your day-to-day activities on Mac OS X, for added security. It seems counter-productive for virus software to require you to lower this level of security by making you work in an admin account. Am I right?
