Izvo zvinongogadzira kopi yakavharidzirwa yefaira rega rega repakutanga, nepo iwo mafaera ekutanga iwo chete anowana iyo "zvakavanzika”Hunhu. Kana izvi zvikaitika, zviri nyore kuzviwana uye kudzoreredza hunhu hwavo chaihwo.
- Vagadziri veRudzikunuro vakaita zvikanganiso zvakawanda uye mhando yekodhi yakaderera kwazvo.
- Kana iwe wakabatwa neWannaCryhlengwareware, pane mukana wakanaka wekuti iwe unozogona kudzoreredza akawanda mafaera pakombuta iyi.
- Kuti udzorere mafaera, unogona kushandisa zvemahara zvinoshandiswa zviripo kuti faira ripore.
