Professional Reviews. Even so, new viruses that got out ahead of database updates left a significant percentage of devices unprotected.
The result was a constant race to keep up with the evolving landscape of threats as new viruses were created and released into the wild. PC viruses today are more of a legacy threat than an ongoing risk to computer users. They've been around for decades and have not substantially changed. So, if computer viruses aren't really a thing anymore, why do people still call their threat protection software an antivirus program, and why do you need an antivirus for computers in the first place?
It boils down to entrenched name recognition. Viruses made sensational headlines in the 90s, and security companies began using antivirus as shorthand for cyberthreats in general. Thus, the term antivirus was born. Decades later, many security firms still use this term for marketing their products. It's become a vicious cycle. Consumers assume viruses are synonymous with cyberthreats, so companies call their cybersecurity products antivirus software, which leads consumers to think viruses are still the problem.
But here's the thing. While virus and antivirus are not exactly anachronisms, modern cyberthreats are often much worse than their viral predecessors. They hide deeper in our computer systems and are more adept at evading detection. The quaint viruses of yesterday have given rise to an entire rogue's gallery of advanced threats like spyware, rootkits, Trojans, exploits, and ransomware, to name a few.
As these new attack categories emerged and evolved beyond early viruses, companies making antivirus for computers continued their mission against these new threats. However, these companies were unsure of how to categorize themselves. Should they continue to market their products as antivirus software at the risk of sounding reductive? Should they use another "anti-threat" term for marketing themselves like "anti-spyware," for example? Or was it better to take an all-inclusive approach and combine everything in a single product line that addressed all threats?
The answers to these questions depend on the company. At Malwarebytes, cybersecurity is our highest-level catchall category. It makes sense to combine our anti-threat effort into a single term that covers more than just viruses. Viruses are just one kind of malware.
There are other forms of malware that are more common these days. Here are just a few:. Adware is unwanted software designed to throw advertisements up on your screen, often within a web browser, but sometimes within mobile apps as well. Typically, adware disguises itself as legitimate or piggybacks on another program to trick you into installing it on your PC, tablet, or mobile device. Spyware is malware that secretly observes the computer user's activities, including browsing activity, downloads, payment information, and login credentials, and then reports this information to the software's author.
Spyware isn't just for cybercriminals. Legitimate companies sometimes use spyware to track employees. A keylogger , spyware's less sophisticated cousin, is malware that records all the user's keystrokes on the keyboard.
This malware typically stores the gathered information and sends it to the attacker seeking sensitive information like usernames, passwords, or credit card details. A computer virus is malware that attaches to another program and, when triggered, replicates itself by modifying other computer programs and infecting them with its own bits of code.
Worms are a type of malware similar to viruses in that they spread, but they don't require user interaction to be triggered. A Trojan , or Trojan Horse, is more of a delivery method for infections than an infection. The Trojan presents itself as something useful to trick users into opening it. Trojan attacks can carry just about any form of malware, including viruses, spyware, and ransomware. Famously, the Emotet banking Trojan started as an information stealer, targeting banks and large corporations.
Later, Emotet operated purely as an infection vector for other forms of malware, usually ransomware. Ransomware has been called the cybercriminal's weapon of choice, because it demands a profitable quick payment in hard-to-trace cryptocurrency. A rootkit is malware that provides the attacker with administrator privileges on the infected system and actively hides from the normal computer user.
Rootkits also hide from other software on the system—even from the operating system itself. Malicious cryptomining , also sometimes called drive-by mining or cryptojacking , is an increasingly prevalent form of malware or browser-based attack that is delivered through multiple attack methods, including malspam, drive-by downloads, and rogue apps and extensions. So instead of letting you cash in on your computer's horsepower, the cryptominers send the collected coins into their own account—not yours.
So, essentially, a malicious cryptominer is stealing your device's resources to make money. Exploits are a type of threat that takes advantage of bugs and vulnerabilities in a system in order to allow the exploit's creator to deliver malware. One of the most common exploits is the SQL injection.
Malvertising is an attack that uses malicious ads on mostly legitimate websites to deliver malware. You needn't even click on the ad to be affected—the accompanying malware can install itself simply by loading and viewing the page in your browser.
All you have to do is visit a good site on the wrong day. Spoofing occurs when a threat pretends to be something it's not in order to deceive victims to take some sort of action like opening an infected email attachment or entering their username and password on a malicious site spoofed or faked to look like a legitimate site. Phishing is a type of attack aimed at getting your login credentials, credit card numbers, and any other information the attackers find valuable.
Phishing attacks often involve some form of spoofing, usually an email designed to look like it's coming from an individual or organization you trust. Many data breaches start with a phishing attack. The old school method of signature-based threat detection is effective to a degree, but modern anti-malware also detects threats using newer methods that look for malicious behavior. To put it another way, signature-based detection is a bit like looking for a criminal's fingerprints. It's a great way to identify a threat, but only if you know what their fingerprints look like.
Modern anti-malware takes detection a step further so it can identify threats it has never seen before. By analyzing a program's structure and behavior, it can detect suspicious activity. Keeping with the analogy, it's a bit like noticing that one person always hangs out in the same places as known criminals and has a lock pick in his pocket.
This newer, more effective cybersecurity technology is called heuristic analysis. Each time a heuristic anti-malware program scans an executable file , it scrutinizes the program's overall structure, programming logic, and data. All the while, it looks for things like unusual instructions or junk code. In this way, it assesses the likelihood that the program contains malware.
What's more, a big plus for heuristics is its ability to detect malware in files and boot records before the malware has a chance to run and infect your computer.
