When purchasing your license, simply select how many Windows PCs you want to protect. During your license period, you can protect any number of Windows up to the total number that your license covers. For example, you could select a 3-PC license to protect up to three different desktops or laptops used in your family.
The need for countermeasures led to the development of the first antivirus software programs. Early online antiviruses were exclusively reactive. They could only detect infections after they took place. Moreover, the first antivirus programs identified viruses by the relatively primitive technique of looking for their signature characteristics. However, if the attacker changed the file name, the computer antivirus might not be as effective. While early antivirus software could also recognize specific digital fingerprints or patterns, such as code sequences in network traffic or known harmful instruction sequences, they were always playing catch up.
Early antiviruses using signature-based strategies could easily detect known viruses, but they were unable to detect new attacks. Instead, a new virus had to be isolated and analyzed to determine its signature, and subsequently added to the list of known viruses.
Those using antiviruses online had to regularly download an ever-growing database file consisting of hundreds of thousands of signatures. 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. But before we get to that, let's set a few things straight so we're all on the same page. When we talk about antivirus products, we're really talking about anti- malware products. Malware is a catchall term that refers to any malicious program created to damage, disrupt, or take charge of a computer.
Types of malware include not only viruses but spyware, trojan horses, ransomware, adware, and scareware. Any good antivirus product in must be able to detect and remove all forms of malware on your computer or server.
Meanwhile, additional features to look for include identity monitoring and alerts, financial loss or identity theft insurance, and some form of browsing protection, such as a VPN, malicious URL blocking, website rating, and phishing protection.
Malwarebytes is one of the most trusted names in malware protection, but for years it was only an add-on program that assistedyour primary antivirus software. Now that's no longer the case. These days Malwarebytes Premium is a full-blown antivirus program. And it's really good. Malwarebytes offers top-of-the-line malware detection and removal, very fast scans, and outstanding protection from phishing sites and malicious URLs. Essential free protection is just one click away.
