  2. My Doom: This deadly virus managed to take Google off-air for almost a day. It is popular for its fast speed and every 1 email out of 12 was infected with a worm and came with a warning message and attachment saying “Mail Transaction Failed”. A single click on the link would spread the virus and leave the system infected.
  3. ILOVEU: This destructive virus first originated in the Philippines in 2000 and caused damage of around $10 billion. It was a spam email campaign that spread emails having “ILOVEU” as the subject line. Apart from this, it was also embedded with an infected attachment file named “LOVE-LETTER-FOR-YOU.txt.vbs”. A mere click on the files could execute the virus and infect the PC.
  4. Melissa: Originated in 1999 Melissa was spread in the form of a word file claiming to include the login credentials of popular adult websites. Upon opening, the virus would send emails to your top 50 contacts. Although the virus was not created to steal data it did a lot of damage to government agencies and corporates.
  5. Cryptolocker: This was the first-ever Ransomware attack that aimed to lock the victim’s PC and demanded ransom for unlocking it. A massive amount of ransom was paid under this attack and accounts at approximately $27 million.
