Mokhoa oa ho Itšireletsa Khahlanong le Litlhaselo tsa Ransomware

Litlhaselo tse hlalositsoeng ka holimo ha li felle feela ho lik'hamphani le mekhatlo ea 'muso. Ho bohlokoa ho hopola hore litlhaselo tse ngata tsa ransomware li lebisa basebelisi ka bomong le bareki lefatšeng ka bophara. Basebelisi ba ka latela litataiso tsena ho thusa ho thibela litlhaselo tsa ransomware le malware le ho thusa ho eketsa ts'ireletso ea inthanete:

• Sireletsa komporo ea hau litlhaselong tse ka bang teng tsa cyber ka lenaneo le matla le khahlanong le malware joalo ka SpyHunter.
