Malware

When the IBM PC was new, I served as the president of the San Francisco PC User Group for three years. That’s how I met PCMag’s editorial team, who brought me on board in 1986. In the years since that fateful meeting, I’ve become PCMag’s expert on security, privacy, and identity protection, putting antivirus tools, security suites, and all kinds of security software through their paces. Since 1982, PCMag has tested and rated thousands of products to help you make better buying decisions. (Opens in a new window) The computer, smartphone, or table you use every day is an example of hardware. The apps and programs that run on your hardware, they’re called software. Some go so far as to use “wetware” to name the brain that uses the software. But there’s a shadier ‘ware lurking, one we call malware. Malicious software can take many forms. Trojan horse programs masquerade as useful tools, hiding activities such as tapping your online bank transactions. Ransomware encrypts your essential documents and demands a no-trace payout to restore them. Keyloggers capture your login passwords along with everything else you do at your computer. But never fear; there are plenty of ways to fight back against the scourge of malware.

Malware definition Malware, short for malicious software, is a blanket term for viruses, worms, trojans and other harmful computer programs hackers use to wreak destruction and gain access to sensitive information. As intended use, rather than a particular technique or technology used to build it. This means that the question of, say, what the difference is between malware and a virus misses the point a bit: a virus is a type of malware, so all viruses are malware (but not every piece of malware is a virus). Types of malware There are a number of different ways of categorizing malware; the first is by how the malicious software spreads. You've probably heard the words virus, trojan, and worm used interchangeably, but • A • A • A Malware can also be installed on a computer "manually" by the attackers themselves, either by gaining physical access to the computer or using privilege escalation to gain remote administrator access. Another way to categorize malware is by what it does once it has successfully infected its victim's computers. There are a wide range of potential attack techniques used by malware: • spies on your behavior as you use your computer, and on the data you send and receive, usually with the purpose of sending that information to a third party. A • A root access (administrator-level control, in Unix terms) over the target system, and use that power to hide their presence. • Adware is malware that forces your browser to redirect to web advertisements, which...

I've been writing about computers, the internet, and technology professionally for 30 years, more than half of that time with PCMag. I run several special projects including the Readers' Choice and Business Choice surveys, and yearly coverage of the Fastest ISPs and Best Gaming ISPs.

Malware, short for malicious software, refers to any intrusive software developed by cybercriminals (often called hackers) to steal data and damage or destroy computers and computer systems. Examples of common malware include viruses, worms, Trojan viruses, spyware, adware, and ransomware. Recent malware attacks have exfiltrated data in mass amounts. What is the intent of malware? Malware is developed as harmful software that invades or corrupts your computer network. The goal of malware is to cause havoc and steal information or resources for monetary gain or sheer sabotage intent. Intelligence and intrusion Exfiltrates data such as emails, plans, and especially sensitive information like passwords. Disruption and extortion Locks up networks and PCs, making them unusable. If it holds your computer hostage for financial gain, it's called ransomware. Destruction or vandalism Destroys computer systems to damage your network infrastructure. Steal computer resources Uses your computing power to run botnets, cryptomining programs (cryptojacking), or send spam emails. Monetary gain Sells your organization's intellectual property on the dark web. How do I protect my network against malware? Typically, businesses focus on preventative tools to stop breaches. By securing the perimeter, businesses assume they are safe. However, some advanced malware will eventually make their way into your network. As a result, it is crucial to deploy technologies that continually monitor and detect...

The main malware categories include Trojans, viruses, worms, and ransomware. There are malware examples targeting all of the major operating systems including those from Apple, Android, and Windows – even Malware only exists to attempt to exploit your device or personal data in some manner, usually for the author’s own gain – say, for example, stealing your online banking details – but sometimes it effectively represents random acts of virtual violence, such as a virus which just nukes your entire system. • Looking for even more protection? Grab the • Macs could be in danger too - see our • See why we rate The problem with viruses There is a lot more to malware than viruses. Computer viruses are a specific type of malware which have two specific characteristics. First, a computer virus can execute or run itself. It does this by attaching itself to other programs or by hiding in the computer code which is run automatically when certain types of files or programs are opened. Second, a virus can replicate itself. This is often done within a targeted program or app within the device, followed by the virus spreading to other devices via emails, USB memory devices, or a vulnerable network. While these technical distinctions are important for analysts, they aren’t for the consumer. The important point for consumers is to realize that a narrowly defined computer virus is just the tip of the iceberg -- there are many more risks and vulnerabilities out there than just that.
