Viruses are the most well-known and probably the most dangerous type of malware. They can do everything from wipe your computer’s data to hijacking it to attack other systems, send spam, or host and share unlawful information. Wondering how to get rid of malwares or Remove Newpoptab Virus?
Let’s dive deeper into that and understand the Top 9 types of Viruses that can affect your browser severely. No. it will leave you stunned.
In September 2013, the CryptoLocker ransomware was published, and it propagated through email attachments, encrypting the user’s files and making them inaccessible. The virus is a deadly type of ransomware that encrypts computer files. In exchange for accessing the file or papers, a victim must pay a set sum in bitcoin. A person/victim should have a private key to decode the file. Once infected, the files are virtually lost for all time.
The Plug X malware, commonly known as “Korplug,” is a Remote Access Trojan (RAT) first detected in 2012. It primarily targets government agencies, enterprises, and organizations, and it spreads through phishing emails, spam campaigns, and spear-phishing tactics.
The assault begins with a phishing email that contains a malicious attachment, usually a specially written malicious document, that exploits a vulnerability in Adobe Acrobat Reader or Microsoft Word.
The Zeus virus was initially found in 2011 as part of the “Zeus” family of malware and viruses. The virus is a type of malicious software designed to infect Microsoft Windows computers. Infections are spread chiefly through spam letters and drive-by downloads.
The Zeus virus’ main goal is to gain access to the victim’s sensitive bank account information and steal all of the victim’s funds. The virus can bypass centralized servers and establish independent servers to send sensitive data, and the victim is unable to track their stolen data.
The Stuxnet computer virus
The Stuxnet worm was initially discovered in 2010 after it was suspected to evolve in 2005. Initially, it was intended to target Iran’s nuclear facilities. The worm caused many centrifuges in Iran’s Natanz uranium enrichment complex to burn out, destroying them. According to Stuxnet log logs, a company called Foolad Technic was the first victim.
Mydoom is number five.
On January 26, 2004, MyDoom, the initial version of the worm, was released. It was spread using email and a peer-to-peer network. This virus is built in the C++ programming language and originated in Russia. The virus installs a backdoor in the operating system of the victim’s machine. It started a denial of service (DoS) attack against the virus on February 1, 2004, and it stopped distributing itself on February 12. The backdoors generated during the early infections remained operational even after the virus had spread. MyDoom, like ILOVEYOU, holds the record for the fastest-spreading email-based worm in history.
Netsky and Sasser
Sven Jaschan, a 17-year-old German, developed Sasser and Netsky.
Sasser was responsible for DDOS attacks, despite the virus doing no physical harm. Although the two worms function differently, the code similarities led security experts to think they were both created by the same person. The Sasser worm is unstoppable; once infected, the virus searches for another vulnerable machine to infect. The malware looks for potential victims by scanning random IP addresses. The virus causes the Internet to slow down and specific websites to completely stop working.
Marc Maiffret and Ryan Permeh, both of eEye Digital Security, found the Code Red worm. Because they were drinking Code Red Mountain Dew, they christened it “Code Red.” The Code Red attack first surfaced in 2001, and it used a buffer overflow flaw in the system to target computers using the Microsoft IIS web server. Once infected, the computer will generate a hundred duplicates of itself, but owing to a programming flaw, it will replicate, even more, consuming a large portion of the system’s resources. It will then conduct a denial-of-service assault against a number of IP addresses, the most well-known of which was the attack on the White House website.
Nimda debuted on September 18, 2001, and quickly spread across the Internet. In fact, it took only 22 minutes for Nimda to reach the top of the list of reported attacks after it was released on the Internet. The main goal of the Nimda virus was to slow down Internet traffic. By installing a backdoor in the target’s operating system, the attacker gains access to the same level of functionalities as the victim. Furthermore, if the victim was the machine’s administrator, the attacker would have complete control.
On May 5, 2000, the ILOVEYOU virus, which originated in the Philippines, began infecting computers. The virus is transmitted via email with the subject “ILOVEYOU” and the attachment “LOVE-LETTER-FOR-YOU.txt.vbs.” When the attachment was opened, a Visual Basic script was run, infecting the computer. It is regarded as one of the most dangerous computer viruses ever devised. It was able to cause havoc on computer systems all across the world, causing an estimated $10 billion in damages. It was estimated that 10% of the world’s computers were infected.
So, how can you safeguard your PC against viruses?
You are responsible for a large part of the defence. Keep your programmer and software up to date by using antivirus software. Firewalls, popup blockers, and strong passwords should all be used with caution.
Of course, the bigger your company gets, the more money you have to lose. These simple procedures for avoiding computer infections are a good start, but will they be sufficient?
Don’t take any chances.
