Yes I do have 2 bypass caps on the circuit

Could you recommend what the best sized caps would be?

You also need the PIC to detect it's receiving the correct digital data, and NOT just any random occurance that makes the output go low.

Yes I have been trying to check out your tutorial page but it hasnt been loading today.

All I had to do was debounce the IR input with a 255 delay.

No more false triggering. Perfect.

Not to mention some phenomenal range too

Forescent lights can cause false triggering on IR modules if there's not method to detect valid data.

Yep, I just shone a floro on it and it activated

Luckily there normally is no floro present

But it will trigger from any random occurance which passes through the IR receiver, this is why you require digital coding on the data stream, so the PIC can determine if it's a valid signal or not.
