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.
{\not\sqsubseteq} with the surrounding brackets, otherwise the placement of the bar can vary. Or even {\not\!\sqsubseteq} to place the bar closer to the middle.
Also, pxfonts will change the font of the whole document.
