Internet -- safety -- tips?

[T U]

Sorry, I really didn't know that the presence of Internet Explorer was so irrelevant. I just asked because previously you answered only about the verion and the state and, in general, I 've "heard" several times - regarding troubleshooting - that it has to be installed, or not in offline state, or to be of a certain version and above etc. and I didn't want its absence to be one of the possibilities if my internet related macros don't work while in another user's computer and have to consider installing it and experimenting. I persolally have been - quite formally - told by a software developer and a technical department, regarding two different programs, to take care of some of the aforementioned parameters. So don't get me wrong for asking.

I get the point now. Thank you.
