Primordial Black Holes (PBHs) are hypothesized to have been formed in the Early Universe as a result of density fluctuations. In recent years, PBHs have gained attention, in part, for the possibility that they can account for a fraction or all the dark matter content of the Universe. PBHs formed with a mass around $10^{14}$g to $10^{15}$g should be evaporating in present times through the emission of Hawking radiation. Such a process leads to a bright burst of very-high-energy (VHE) particles. The primary and secondary VHE photons produced could be detected by gamma-ray experiments. However, no observational evidence has been found yet for PBH evaporation emission, with current upper limits on the local explosion rate set to $181\, \mathrm{pc}^{-3} \mathrm{yr}^{-1}$. In this talk I'll report on the search for PBH evaporation signals in 2000 hours of archival MAGIC data. I'll present the new search methodology, statistical techniques and results of the analyzed data.
