How can I tell if my Android device has malware?

Fortunately, there are a few unmistakable red flags that wave at you if your Android phone is infected. You may be infected if you see any of the following:

  • A sudden appearance of pop-ups with invasive advertisements. If they appear out of nowhere and send you to sketchy websites, you’ve probably installed something that hides adware within it. So don’t click on the ad.
  • A puzzling increase in data usage. Malware chews up your data plan by displaying ads and sending out the purloined information from your phone.
  • Bogus charges on your bill. This happens when malicious software makes calls and sends texts to premium numbers.
  • A disappearing battery charge. Malware is a resource burden, gulping down your battery’s juice faster than normal.
  • People on your contact list report strange calls and texts from your phone. Malware replicates by spreading from one device to another by means of emails and texts, inviting them to click on the infected link it displays.
  • A phone that heats up while performance lags. For instance, there’s even a Trojan out there that invades Android phones with an installer so nefarious, that it can tax the processor to the point of overheating the phone, which makes the battery bulge, and essentially leaves your Android for dead.
  • Surprise apps on your screen. Sometimes you download apps that have malware piggybacked onto them for a stealthy installation. That happens because Android allows users to jump straight from Google Play to other marketplaces, like Amazon, which might have let a malware maker slip through.
  • Your phone turns on WiFi and Internet connections on its own. This is another way malware propagates, ignoring your preferences and opening up infection channels.
  • Further down, we’ll touch upon what you should do if your Android is infected. Plus, here’s a Malwarebytes blog article on securing your privacy on an Android.

What are the most common forms of malware?

Here are the most common offenders in the rogues’ gallery of malware:

  • Adware is unwanted software designed to throw advertisements up on your screen, most often within a web browser. Typically, it uses an underhanded method to either disguise itself as legitimate, or piggyback 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 without permission and reports it to the software’s author.
  • A virus is malware that attaches to another program and, when executed—usually inadvertently by the user—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, self-replicating in order to spread to other computers over a network, usually causing harm by destroying data and files.
  • A Trojan, or Trojan horse, is one of the most dangerous malware types. It usually represents itself as something useful in order to trick you. Once it’s on your system, the attackers behind the Trojan gain unauthorized access to the affected computer. From there, Trojans can be used to steal financial information or install threats like viruses and ransomware.
  • Ransomware is a form of malware that locks you out of your device and/or encrypts your files, then forces you to pay a ransom to get them back. Ransomware has been called the cyber criminal’s weapon of choice because it demands a quick, profitable payment in hard-to-trace cryptocurrency. The code behind ransomware is easy to obtain through online criminal marketplaces and defending against it is very difficult.
  • Rootkit is a form of malware that provides the attacker with administrator privileges on the infected system. Typically, it is also designed to stay hidden from the user, other software on the system, and the operating system itself.
  • A keylogger is malware that records all the user’s keystrokes on the keyboard, typically storing the gathered information and sending it to the attacker, who is seeking sensitive information like usernames, passwords, or credit card details.
  • Malicious cryptomining, also sometimes called drive-by mining or cryptojacking, is an increasingly prevalent malware usually installed by a Trojan. It allows someone else to use your computer to mine cryptocurrency like Bitcoin or Monero. So instead of letting you cash in on your own computer’s horsepower, the cryptominers send the collected coins into their own account and not yours. Essentially, a malicious cryptominer is stealing your resources to make money.
  • Exploits are a type of malware that takes advantage of bugs and vulnerabilities in a system in order to allow the exploit’s creator to take control. Among other threats, exploits are linked to malvertising, which attacks through a legitimate site that unknowingly pulls in malicious content from a bad site. Then the bad content tries to install itself on your computer in a drive-by download. No clicking is necessary. All you have to do is visit a good site on the wrong day.

How do I get malware?

“Malware attacks would not work without the most important ingredient: you.”

Bottom line, it’s best to stick to trusted sources for mobile apps, only installing reputable third-party apps, and always downloading those apps directly from the vendor—and never from any other site. All in all, there is a world of bad actors out there, throwing tainted bait at you with an offer for an Internet accelerator, new download manager, hard disk drive cleaner, or an alternative web search service.

Even if you install something from a credible source, if you don’t pay attention to the permission request to install other bundled software at the same time, you could be installing software you don’t want. This extra software, also known as a potentially unwanted program (PUP), is often presented as a necessary component, but it often isn’t.

Another wrinkle is a bit of social engineering that a Malwarebytes expert observed in the UK. The scam hit mobile users by taking advantage of a common mobile direct-to-bill payment option. Users visited mobile sites, unwittingly tripping invisible buttons that charge them via their mobile numbers, directly billing the victims’ networks, which pass the cost onto their bill.

To be fair, we should also include a blameless malware infection scenario. Because it’s even possible that just visiting a malicious website and viewing an infected page and/or banner ad will result in a drive-by malware download.

On the other hand, if you’re not running an adequate security program, the malware infection and its aftermath are still on you.

How do I remove a Trojan?

Once a Trojan infects your device, the most universal way to clean it up and restore it to a desired state is to use a good quality, automated anti-malware tool and make a full system scan.

There are many free anti-malware programs—including our own products for Windows, Android, and Mac—which detect and remove adware and malware. In fact, Malwarebytes detects all known Trojans and more, since 80% of Trojan detection is done by heuristic analysis. We even help mitigate additional infection by cutting off communication between the inserted malware and any backend server, which isolates the Trojan. The only exception is for protection against ransomware, for which you need our premium product.

Malware Infections

Malware can infect a computer or other device in a number of ways. It usually happens completely by accident, often by downloading software that has malicious applications bundled with it.

Some malware can get on your computer by taking advantage of security vulnerabilities in your operating system and software programs. Outdated versions of browsers, and often their add-ons or plugins as well, are easy targets.

But most of the time malware is installed by users (that’s you!) overlooking what they’re doing and rushing through program installations that include malicious software. Many programs install malware-ridden toolbars, download assistants, system and internet optimizers, bogus antivirus software, and other tools by default unless you explicitly tell them not to.

Another common source of malware is from software downloads that seem at first to be safe—like a simple image, video, or audio file—but in reality, is a harmful executable file that installs the malicious program. This is common with torrents.

Do Macs get malware?

Conventional wisdom has sometimes held that Macs and iPads are immune to catching viruses (and don’t need an antivirus). For the most part, that’s true. At the very least, it hasn’t happened in a long time.

“Mac systems are subject to the same vulnerabilities (and subsequent symptoms of infection) as Windows machines and cannot be considered bulletproof.”

Other kinds of malware are a different story. Mac systems are subject to the same vulnerabilities (and subsequent symptoms of infection) as Windows machines and cannot be considered bulletproof. For instance, the Mac’s built-in protection against malware doesn’t block all the adware and spyware bundled with fraudulent application downloads. Trojans and keyloggers are also threats. The first detection of ransomware written specifically for the Mac occurred in March 2016, when a Trojan-delivered attack affected more than 7,000 Mac users.

In fact, Malwarebytes saw more Mac malware in 2017 than in any previous year. By the end of 2017, the number of new unique threats that our professionals counted on the Mac platform was more than 270 percent higher compared to the number noted in 2016.

How do I get ransomware?

Malspam uses social engineering in order to trick people into opening attachments or clicking on links by appearing as legitimate—whether that’s by seeming to be from a trusted institution or a friend. Cybercriminals use social engineering in other types of ransomware attacks, such as posing as the FBI in order to scare users into paying them a sum of money to unlock their files.

Another popular infection method, which reached its peak in 2016, is malvertising. Malvertising, or malicious advertising, is the use of online advertising to distribute malware with little to no user interaction required. While browsing the web, even legitimate sites, users can be directed to criminal servers without ever clicking on an ad. These servers catalog details about victim computers and their locations, and then select the malware best suited to deliver. Often, that malware is ransomware.

Malvertising often uses an infected iframe, or invisible webpage element, to do its work. The iframe redirects to an exploit landing page, and malicious code attacks the system from the landing page via exploit kit. All this happens without the user’s knowledge, which is why it’s often referred to as a drive-by-download.
