What is the most dangerous computer virus in the world?
There are a few different contenders for the title of most dangerous computer virus in the world. The first is the WannaCry virus, which was responsible for a global ransomware attack in May of 2017. This virus encrypted the files on infected computers and demanded a ransom payment in order to decrypt them. The second is the Petya virus, which was also responsible for a ransomware attack, this time in June of 2017. This virus not only encrypted files, but also overwrite the master boot record, making it impossible to boot up the infected computer. The third is the Zeus virus, which is a type of banking trojan that has been used to steal millions of dollars from bank accounts around the world. This virus is particularly dangerous because it is difficult to detect and can cause a lot of financial damage.
What are the different types of computer viruses?
There are numerous types of computer viruses, but they can generally be divided into two categories: macro viruses and Trojans.
Macro viruses are written in the same language as the applications they infect, such as Microsoft Word or Excel. When a macro virus is executed, it infects the application and causes it to replicate itself. The virus then lies dormant until the application is opened again, at which point it will infect any files created or opened with the infected application.
Trojan viruses, on the other hand, do not replicate themselves but instead execute a malicious payload. The payload might be anything from deleting files to encrypting all the data on a hard drive. Trojans are often spread via email attachments or downloads from untrustworthy websites.
Both macro viruses and Trojans can be extremely harmful, so it’s important to have a good antivirus program installed on your computer and to be cautious when opening email attachments or downloading files from the internet.
