Almost everyone who surfs the internet and enjoys what it has to offer lives in fear of a terrible virus that they might come across in some corner of the internet. This virus can be so terrible that it destroys everything from your screen to your precious data. Many times we have come across various stories of such viruses from various websites (serious and not) because no matter how we do it, the subject is catchy. But what is actually happening? Are there such "monsters"? The security company Kaspersky with a historical review he recorded the 8 scariest viruses in the history of the internet. Most of them come from the DOS era, when computers were simpler. These viruses were written as a way of expression and not for financial gain, as is done today. Let's look at them one by one.
Cascade:
There is nothing worse than watching your system literally fall apart. This is what the Cascade virus did in the late 80s and early 90s. When it installs, you will notice DOS characters at the bottom of it screen your which come and go, after that your system is literally useless. It seems that an episode of "Star Trek: Voyager" used the same name for a virus.
Madman:
The virus wasn't terribly damaging, but it displayed a surprising red image with two eyes and then displayed the text “Nothing can save you. Dude, you're in my world now” If you tried to remove the image or the virus it displayed the message “I'm watching you.”
AIDS:
It was one of the scariest viruses ever released. It was released in the early 90s and informed its victims with a welcome message that their system was infected with AIDS. System had to reboot but no hope operation. For it to work again computer all infected .COM files should be removed and replaced with new ones.
Skulls:
The Trojan was written for Symbian systems, a mobile operating system that was popular from 2001 to 2004. The virus filled the mobile screen with skulls and bones, replacing app icons and rendering them useless. Kaspersky Lab experts named the virus Vandal Trojan.
Tequila:
The Tequila virus infects DOS .exe files. The infected system displayed a fractal image – a graphical representation of a mathematical formula – with the text: “… T.TEQUILA's latest production. Contact T.TEQUILA/PoBox 543/6312 St'hausen Switzerland. Loving thought to LINDA BEER and TEQUILA forever!” The message had absolutely nothing to do with the action of the virus.
nail:
Another DOS virus that showed up with an impressive image on infected systems. Kuku featured colorful tiles that slowly fill the screen and while continuously flashing the word Kuku appears.
Rigel:
Ο ιός των Windows μετά την εγκατάσταση του άρχιζε να σχεδιάζει όλα τα library των Windows με εικονίδια τα οποία σιγά σιγά κάλυπταν ολόκληρη την οθόνη. Δεν επηρέαζε άμεσα άλλες λειτουργίες, αλλά κανείς δεν μπορούσε να δει τίποτα καθώς η οθόνη ήταν όλη καλυμμένη με τα σχέδια του ιού.
Gruel:
One of the first Windows worms that was one of the first forms of fake antivirus programs that come as a security patch that is actually nothing but a virus. After installation, various Windows folders would open by themselves and the CD-ROM drawer would open by itself. Then the following message came: "O computerς σας είναι πια δικός μου, γιατί; Επειδή δεν είχα τίποτα να κάνω και σκέφτηκα, γιατί να μην κάνω κάτι κακό; Remember NOW YOUR PC IS IN MY POWER Windows Sucks! I can't stand it anymore!” And on and on, singed, ‘KILLERGUATE.'
