This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Do you want not (a subset or equal) or a subset but not equal? – Roelof Spijker Nov 14 '11 at 9:22

The easiest way is to prefix the symbol with \not, as in \not\sqsubseteq. Alternatively, pxfonts provides \nsqsubseteq.

For more symbols in LaTeX, peruse Scott Pakin's Comprehensive LaTeX Symbol List.
