All malware is created to commit crimes. What’s important to hackers is doing harm, causing damage, and the criminal earnings that result from those activities. What threats does Dr.Web protect against?



Against banking Trojans, keyloggers, and hacker attacks during online banking sessions

  • The Firewall will prevent hackers from penetrating your device when you’re checking your account and making payments via online banking services; it will also protect against data and information theft.
  • Preventive Protection will neutralise any banking Trojans and ransomware trying to launch on your device.
  • The SpIDer Guard file monitor will prevent keyloggers from being launched on your device and stealing your logins and passwords.
  • The Call and SMS filter in Dr.Web for Android will prevent the theft of bank SMS messages containing transaction response codes—this will prevent criminals from making transactions, instead of you.

 Protection against scammers

Against phishing and fraudulent sites and sites containing malware

With the help of social-engineering techniques, scammers deceive Internet users by playing on their curiosity, weaknesses, and carelessness. And Dr.Web protects users against scammers, using its entire array of anti-virus technologies.

  • The Anti-spam will filter out phishing emails—you simply won’t see messages sent by criminals and you won’t fall into their traps. It’s also a time saver—you won’t have to waste time “cleaning” your mailbox of unwanted advertising.
  • The HTTP monitor SpIDer Gate will prevent users from visiting phishing sites, fake online bank or store pages, and the sites of other fraudsters, sorcerers, witch doctors, makers of miracle cures, and medical charlatans.
  • To prevent your gaming currency and expensive artifacts from flowing into the accounts of cybercriminals, never disable the SpIDer Guard file monitor. Its continuous operation will spare both your nerves and your data.

 Data and information protection

Prevents information from being deleted, damaged, encrypted or stolen.

Each of us values the fruits of our labours and our family photos and movies. But for hackers, such files are their key to getting rich.

SpIDer Guard will instantly neutralise any attempts made to damage your files or steal them from your device.


 Protection against program vulnerabilities

Against exploits used by cybercriminals to penetrate systems via errors in popular applications

Vulnerabilities exist in every piece of software. This fact is well known to hackers, which is why they create exploits—special codes that exploit vulnerabilities to deliver malicious applications into a system or steal information. Cybercriminals most frequently exploit vulnerabilities in popular browsers, Adobe applications, and Office systems. Any software has loopholes. Zero-day vulnerabilities—those vulnerabilities not yet known to either software developers or even anti-viruses—are particularly dangerous.

  • Dr.Web Process Heuristic technology will analyse the behaviour of each running program in real time by comparing it with the reputation information stored in the Dr.Web cloud, which is constantly updated. It will determine whether a program is dangerous and then take whatever measures are necessary to neutralise the threat.
  • Dr.Web ShellGuard technology will detect when malicious code attempts to exploit a vulnerability and terminate the attacked process immediately, thus preventing the exploit from running.
  • The Dr.Web heuristic analyser will use its knowledge (heuristics) about certain properties typical of viruses to stop an exploit.

Protection for data and information

Against deletion, corruption, theft, and encryption

Each of us values the fruits of our labours and our family photos and movies. But for hackers, such files are their key to getting rich.

  • The Data Loss Prevention feature will keep your most important information safe, constantly protecting it from tampering or deletion.
  • The Ransomware Fighter module prevents encryption ransomware from being launched in a system; this will protect users from blackmailers who demand a ransom for data recovery.
  • SpIDer Guard will instantly neutralise any attempts made to steal files from your device.
  • The Devices component will make it impossible for anyone to connect to your network-connected devices, which means it will be impossible for them to record information from your computer.

 Protection against device hijacking and spying

Camera, microphone, and removable device control

Dr.Web believes: a computer should serve its user rather than invisible intruders who can utilise the machine's resources remotely for their shady dealings. That’s why Dr.Web developers pay a lot of attention to providing protection against hijacking and spying.

  • Miners are quick to use other people’s computers for personal enrichment, an activity known as crypto mining. Dr.Web protects computers against such break-ins and does not let cybercriminals use your system resources. Your computer will remain yours!
  • Today criminals gather infected computers into remotely controlled groups known as botnets. This lets them carry out massive attacks that result in denial of service; such attacks can be ordered against companies by their competitors and against military facilities and infrastructure-critical institutions. When such attacks are being investigated, your computer may be disconnected from the Internet or confiscated for investigative purposes. Use Dr.Web if you don't want your device to become part of a botnet.
  • Devices disguised as removable media can “burn” part of a computer or intercept data. Use the component and block such attempts.
  • Cyber spies have different goals in mind when they monitor users: blackmail, extortion, revenge... And sometimes it’s just for fun or because of various mental disorders. To protect your privacy, Dr.Web will block hacker attempts to use your microphone or camera. You will be able to work at your computer without having to worry about your photos getting published on the Internet or the results of a meeting becoming known to your competitors.

 Protection for children against psychological and moral harm

Parental Control

Children constitute a special group of Internet users that is most at risk due to inexperience, credulity, curiosity, and other age-related qualities. Therefore, the ways of protecting children on the Internet are special too.

  • Parental Control will prevent children from visiting websites that can have disastrous psychological and moral impact; it will keep them from communicating with scammers of all stripes, criminal elements, and mentally disturbed people.
  • Filtering sites according to thematic groups will block children from accessing websites their parents deem inappropriate: social media sites, gambling sites promoting violence, etc.
  • Parents can restrict access to their documents and make it impossible for their children to view information intended for adult eyes only.
  • Dr.Web gives parents the ability to restrict online time so that their children aren’t engaging in health-harming, excessive Internet use and are spending more time on their studies, interacting with peers, and engaging with the world.

About Dr.Web’s anti-ransomware protection

  1. About the odds of decryption

    • Ever since the first encryption ransomware programs appeared in 2006, Doctor Web’s specialists have been gathering statistics on the number of infection incidents and the number of successful decryptions. On average, the percentage of successful decryptions fluctuates as follows: 1 decryption per every 10 infection incidents—i.e., the effectiveness is only 10%. When dealing with some encryption ransomware, the percentage of decryption is equal to zero. That’s not the fault of Doctor Web’s security researchers. It’s because of the technical features of certain encryption ransomware programs. Some encoders are created using strong algorithms. It will take 107,902,838,054,224,993,544,152,335,601 years to simple search a key to restore files compromised by Trojan.Encoder.741.
    • More than 50% of the support requests received by Doctor Web have been submitted by private users and companies whose data was compromised by encryption ransomware. We can help some of them and have had success. But it’s impossible to help everyone—this is an objective reality.
    • By the way, did you know that users whose data was compromised by the much-talked-about WannaCry, which managed to bypass almost all anti-viruses, lost their data permanently? That’s because it’s technically impossible to decrypt this particular encryption ransomware. By the way, no Dr.Web user’s data was compromised by WannaCry.
  2. Encryption ransomware is malware (Trojans) that cannot replicate and launch itself. As a rule, programs of this kind are launched by users. Usually Trojans can be launched in a system because users fail to follow the anti-virus developers’ recommendations on how to configure the anti-virus software. Those user shortcomings usually include:
    • a failure to update the anti-virus software during an extended period of time. Discarding updates and system restart prompts after an update has been installed, thus preventing a new driver, which would intercept the latest encryption ransomware, from being installed;
    • using outdated versions of an anti-virus that lacks state-of-the-art technologies as well as anti-virus versions that lack components that would offer protection against today’s threats (an anti-virus only, instead of a comprehensive security solution);
    • completely disabling the anti-virus protection—sometimes in response to recommendations found in phishing emails!— as well as toggling off some protection modules or incorrectly configuring the following features: a) the behaviour analyser, which identifies up to 99% of encryption ransomware that is not yet known to the anti-virus engine, b) the HTTP monitor SpIDer Gate, which keeps users from visiting sites used by criminals to distribute malware c) the anti-spam, which detects 98% of phishing emails—the main transport of encryption ransomware that delivers the programs as executable attachments or special scripts that download Trojan executable files;
    • excluding from scanning entire classes of files with certain extensions and even individual applications (e.g., browsers).

    All the user actions that can launch encryption ransomware are described in detail in our interactive project Tune up your PC against ransomware and in a similarly named brochure.

    Doctor Web’s specialists understand that for a user whose data has been compromised by encryption ransomware, it makes no difference whether the culprit was the much-talked-about WannaCry, which managed to bypass almost all anti-viruses (by the way, no Dr.Web user’s data was compromised by it) or some little-known encryption ransomware. We try out best to add signatures to our virus databases as quickly as possible, but the struggle against encryption ransomware is impossible without the cooperation of the user who has an anti-virus.

  3. Ransomware makers modify their programs on a daily basis to make sure that no anti-virus can detect them when they are being dispatched into the wild. No anti-virus can, at any point in time, detect all malicious programs, including encryption ransomware. All anti-viruses can fail to detect encryption ransomware. Any system can be infected by new, unknown ransomware. By the way, no Dr.Web user’s data was compromised by the much-talked-about WannaCry which managed to bypass almost all anti-viruses.
