What is the most dangerous computer virus and why?
There is no definitive answer to this question as it largely depends on the perspective of the person answering. For some, the most dangerous virus might be one that corrupts or deletes critical files, rendering a computer inoperable. For others, it might be a virus that steals confidential information or one that allows remote access to a computer for malicious purposes.
No matter what criteria is used to determine the most dangerous virus, there are a few that stand out from the rest. The first is the Conficker virus, which was first detected in 2008. This virus targets computers running Microsoft Windows and can spread quickly through networks. Once a computer is infected, the virus can disable security features and prevent access to certain websites, including security sites that offer help in removing the virus.
Another dangerous virus is known as Cryptolocker. This virus encrypts files on an infected computer, making them inaccessible unless a ransom is paid to the attackers. Cryptolocker is particularly dangerous because it can infect not only individual computers but also servers, which can lead to the loss of important data for businesses or organizations.
Finally, the ransomware known as WannaCry is considered to be one of the most dangerous computer viruses in recent years. This virus infected more than 200,000 computers in over 150 countries in 2017. The WannaCry virus encrypted files on infected computers and demanded a ransom of $300 worth of Bitcoin in order to decrypt the files. This virus caused widespread panic and led to hospitals, businesses, and other organizations being shut down as a result of the attack.
While there are many other computer viruses that could be considered dangerous, these three stand out as being particularly destructive or harmful. The Conficker virus can disable security features and prevent access to critical websites, Cryptolocker can encrypt important files and render them inaccessible, and WannaCry can shut down entire networks of computers.
What are the most effective ways to protect against computer viruses?
There are a few key things you can do to protect your computer from viruses. First, install an antivirus program and run regular scans. This will help to catch any viruses that make it past your other defenses. Next, be careful about what you download and install. Don’t open email attachments from people you don’t know, and be cautious about clicking on links in email or on websites. It’s also a good idea to keep your operating system and software up to date, as updates often include security improvements that can help protect against new threats. Finally, practice good computer hygiene by not sharing your passwords, backing up your data, and using a safe browsing extension like uBlock Origin.
