On pronunciation, is it "ASTERISK" or ASTERIK..(silent 'S')?

[Percival]

I was born, raised, and educated in the Philippines.When I migrated here in the U.S., I've discovered so many English words that are pronounced differently.
Most of my co-workers in the office pronounce the word ASTERISK (*), as...as-te-rik(silent 's').In the Philippines, we pronounce the "s", as in RISK. What's right, ASTERISK or ASTERIK ?
Another mind boggling is the pronunciation of ASK as AKS...enlighten me please!

[Mister Micawber]

The 's'; should be pronounced. In the US, many people learn it without the 's', but it is a sign of a poor education.
