OS X 10.9.3

Question

Hello, about 2 days ago I installed the 10.9.3. update released by apple and my Mac Book Pro just keeps malfunctioning.
Most of my applications crash when opening. Working around the computer became really frustrating because it is much slower and things just keep crashing.
I can post the error details for chrome for example if you think it helps you find the problem.
I reinstalled OS X already and nothing changed.
Thank you,
João Cardoso
