That being said, anti-malware can stop an online viral infection from happening and remove infected files. However, anti-malware isn't necessarily equipped to restore files that have been changed or replaced by a virus.

Both antivirus software and anti-malware fall under the broader term " cybersecurity. Cybersecurity, or computer security, is a catchall term for any strategy for protecting one's system from malicious attacks, including both antiviruses and anti-malware.

These attacks often aim to do things like hold your computer hostage, steal system resources as in a botnet , record your passwords and usernames, and a whole host of other bad things.

Such attacks might occur via your hardware like a backdoor or through your software like an exploit. Cybersecurity threats and their countermeasures are varied and nuanced nowadays, but the marketplace naturally strives for simplicity when communicating to consumers. In reality, computer viruses are just one type of cyberthreat that happened to be popular when computers were in their infancy.

They're far from the most common threat today, but the name stuck. It's a bit like calling every disease a cold. They both refer to software designed to detect, protect against, and remove malicious software. It needs to be initiated by an unsuspecting user. Triggering a virus can be as simple as opening a malicious email attachment malspam , launching an infected program, or viewing an ad on a malicious site adware.

Once that happens, the virus tries to spread to other systems on the computer's network or in the user's list of contacts. It must be self-replicating. If the software doesn't self-replicate, it's not a virus. This process of self-replication can happen by modifying or completely replacing other files on the user's system. Either way, the resulting file must show the same behavior as the original virus.

Computer viruses have been around for decades. Early viruses occurred on pre-personal computer platforms in the s. However, the history of modern viruses begins with a program called Elk Cloner , which started infecting Apple II systems in Disseminated via infected floppy disks, the virus itself was harmless, but it spread to all disks attached to a system. It spread so quickly that most cybersecurity experts consider it the first large-scale computer virus outbreak in history.

Early viruses like Elk Cloner were mostly designed as pranks. Their creators were in it for notoriety and bragging rights. However, by the early s, adolescent mischief had evolved into harmful intent. PC users experienced an onslaught of viruses designed to destroy data, slow down system resources, and log keystrokes also known as a keylogger.

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. Comodo Antivirus for Windows 10 is free to use, and has a few annoying quirks that are common to free software. During installation, it went right to work modifying our browser, resetting its home and new tab pages to Yahoo, as well as changing the default search engine. It is possible to avoid this by unchecking various boxes during installation, but speeding through without really reading the fine print will leave your browser in a mess.

It's not all bad news though; the installer also offers to install some important features, including Comodo's secure Dragon Browser and Comodo Secure DNS. When you install the Comodo Dragon browser, your full Chrome settings such as bookmarks, cookies, and history are imported automatically. This is convenient if you're a fan of Google's browser, but we'd also like to see some support for others as well. Avast, for example, grabs settings from both Chrome and Firefox when its secure browser is installed.

Setup takes some time due to a slow pre-installation scan and a virus database update that took two minutes to complete in our tests. Comodo Antivirus for Windows 10 provides a flexible interface with options to suit different purposes. Security status check-ins and scans are easily initiated with a tiny desktop widget, with another option to access the more traditional antivirus console.

There's also an Advanced View available, which provides instant access to Comodo's most powerful features. There are plenty of options for new users Comodo can perform just like other antivirus programs, with a choice of quick and full scans , but power users will want to step up to Comodo's advanced options.

These include a Rating Scan, which checks running processes, focusing on commonly infected areas, and provides a reputation score for everything it finds. Some processes aren't full fledged malware, but are marked out as untrusted due to their behavior. If you suspect that your PC might be infected by a new type of malware, but need verification, the Rating Scan can point you in the right direction.

When it comes to regular antivirus scans, Comodo can check your whole PC, or focus on specific files and folders. It can also focus on commonly infected locations, or just scan the processes currnetly running.

Individual scans can be fine-tuned in various ways, with adjustable heuristics the ability to check for new threats that haven't yet been catalogued , the option to check for reputation scores online, and an adaptable scheduler. You can choose to run scans on a regular schedule Tuesdays at 3pm, for example , or scan your PC only on weekdays, or when the system is totally idle powered by AC current.

The choice is yours. It's important to create this while your PC is running smoothly, and keep it in a safe place for emergencies. Comodo Antivirus has the same feature as the paid Comodo Advanced Antivirus, the main difference is the free version lacks support. If your system has been infected with malware, only Comodo paid customers will have an expert cleaning up your PC of all malwares remotely and ensuring your PC remains clean.

Comodo Windows Antivirus has a better approach. Honestly, I am still somewhat confused on how they generate revenue when they give away most of their products. The other thing with free antivirus is it will come with nagware, a pop-up message reminding you how awesome their product is and the need to upgrade. The free Internet Security Software provides a complete protection against viruses and attacks. Comodo Secure Shopping provides unbeatable security for online banking and shopping sessions by ensuring you connect to those websites from within a security-hardened browsing environment.

The Integrated Firewall includes the buffer-overflow protection originally featured in Comodo Memory Firewall.
