The most dangerous computer viruses

COMPUTER VIRUSES

Invalid IMEI

The world is now afraid of COVID-19, but that doesn't mean our computers and smartphones are suddenly safe. Computer viruses, as appalling as they may seem, are a big nightmare that can disrupt your PC's performance significantly. Apparently, their purpose is to spoil your innocent machine by making it helpless and sick. Let's look at some of these viruses, and be careful of your PC or mobile.

Hacking

Sasser

Sasser was a Windows worm that was discovered in 2004. Apparently, it slowed down and crashed the computer, making it difficult to even reset without cutting off the power. Its effects were also surprisingly troublesome as millions of computers were infected and critical infrastructure was affected. The worm was playing due to a buffer overflow vulnerability in the Local Security Authority Subsystem Service (LSASS), which monitors the security policy of local accounts, causing the computer to crash. The devastating effects of the virus were enormous, causing over a million infections.

My Doom

My Doom entered the malware world in 2004 and spread exponentially via email with random sender addresses and subject lines. By infecting around two million computers, My Doom destroyed the cyber world with a massive denial of service attack. It was e-mailed in a particularly deceptive manner so that the recipient would first think of the returned error message which reads "Transaction Failed". However, as soon as the recipient clicked on the message, the attachment was executed and the worm was sent to the e-mail addresses found in the user's address book.

ILOVEYOU

Possibly the most virulent computer virus ever created, the ILOVEYOU virus has managed to destroy PCs all over the world. By infecting nearly 10% of the world's computers connected to the Internet, the virus has caused damage totaling approximately $ 10 billion. The virus apparently was emailed with the subject "ILOVEYOU", which is a radical human emotion that no one can ignore. The moment someone opened the file, the virus e-mailed itself to the first 50 contactsavailable in the Windows address book on the computer.

Melissa

Melissa became breakthrough news on March 26, 1999, as she entered a new era of email. Melissa, built by David L., was distributed as an attachment to an e-mail under the name "list.doc". When someone clicked on the attachment, the virus found the Microsoft Outlook Address Book and sent an email to the first 50 contacts in the list with the message "Here is the document you asked for ... don't show anyone else".
