A disastrous parasitic infection CIH otherwise called "Chernobyl" was first arisen in the year 1998 in Taiwan and immediately became one of the most perilous and horrendous infections to at any point hit with a payload that taints information.
The CIH infection contaminates Windows 95 and 98 executable document and subsequent to doing that it stays an occupant in the machine's memory, where it taints other executables. When enacted, the infection obliterates the information on the hard circle and overwrites the PC's Glimmer Profiles chip, delivering it totally inoperable and except if the chip is reconstructed the client can not boot the machine by any means. Despite the fact that with expanded mindfulness and progression in innovation the infection doesn't represent a serious danger today yet we can always remember the $250 million worth of obliteration it caused.
Assessed Harm: $20 to $80 million around the world; endless measures of PC information annihilated.
