A worm

[netibiza]

My norton anti-virus keeps popping up and saying I have worm trying to get in - I think that's what it says but its in Spanish then is says "alow" or " block" does this mean allow norton to search and destroy or allow the prog with the worm, so should I block it or is that blocking Norton from doing its work.

It means allow the program, which you definitely do not want, Block it.

It won't be trying to get in, but to get out - either to send details harvested from your machine, or to send out new copies of itself
