no pads will cause squealing; no manufacturer put a compound together, glued them to a backing plate, stuck them in a car for a test, heard them squeal like a pig and said "great, let's get them on the shelves". And I mean up to and including sprint or endurance race pads.
Yes some more agressive pads are more likely to be noisey but it is always a problem with the car and/or installation.
Squeal is a high frequency vibration in something that shouldn't be moving. Like GTSboy said above machining rotors and pads may help if they aren't new (flat), any moving parts like sliding pins, caliper pistons, touch point between pistons and pads (which should be anti squeal shims), hub to disc mounting surface, caliper bolts tight. By far the most common cause is simply brake dust, so get everything nice and clean when you reassemble.
If the noise goes away when you add anti squeal goop between the piston and pad that tells you the problem is likely in that contact somewhere. So clean and check the shims are not bent etc
