What is the most common computer virus?
A computer virus is a type of malware that, when executed, replicates itself by modifying other computer programs and inserting its own code. When this replication succeeds, the affected areas are then said to be “infected” with a virus. Viruses are often spread by attaching themselves to files that can be transferred from one computer to another. When a virus is spread in this way, it is often referred to as a “worm”.
The most common computer virus is the “WannaCry” virus. This virus was first discovered in May of 2017 and quickly spread around the world, infecting more than 230,000 computers in 150 countries. The WannaCry virus encrypted data on infected computers and demanded a ransom be paid in order to decrypt the data. This virus caused more than $4 billion in damages and was one of the largest cyber-attacks in history.
