Updates are not downloading
Dr.Web for macOS reliably protects Macs from all types of threats—viruses, rootkits, trojans, spyware and adware, hacker utilities and various malicious objects—using the latest technologies for detecting and neutralising viruses.
Dr.Web components are constantly updated, and the virus databases and databases of web resources categories are regularly expanded to include new threat signatures. Updates provide an up-to-date level of device protection. Heuristic analysis methods are used to neutralise unknown threats.
The main features of Dr.Web anti-virus:
The current list of supported versions can be found in the Documentation for Dr.Web Home Security Suite / Dr.Web Security Space (for macOS).
Malware programs for macOS exist, but compared with Windows, their number is relatively small. For more information about macOS threats, follow this link.
Yes. The first virus for an Apple computer was created in 1982. The first virus for macOS (Mac.Leap) appeared in 2006. In early 2009, the Trojan Mac.Iservice infected machines that comprised the iBot zombie network. In 2012, half a million of computers were connected to the botnet created by the Trojan BackDoor.Flashback. It was Doctor Web who first discovered this zombie network.
Once the anti-virus is installed, a notification will appear, saying "Your permission is required to scan the file system":
The notification will appear after each device restart, and hourly thereafter, if ignored.
To grant permission for the scan, you should:
In case the notifications were ignored, the Allow access button is added to the "General" settings section:
After clicking on this button, proceed as described above.
A special case when there is a drive access permission issue — the SpIDer Guard component is not activated on macOS Ventura. In this case:
An attacker does not necessary need to hack into your computer to install malicious software. In most cases, unwanted programs get onto Macs due to careless of users when they visit legitimate sites, such as news portals. They can be compromised, so that infection gets onto computers of visitors regardless of their OS—in most cases, the target platform is detected and selected automatically.
Two simple conditions must be met for a system to get infected with BackDoor.Flashback.39: Java Virtual Machine must be installed in the system, and a user must load a compromised webpage in the browser.
Trojan.SMSSend family programs can be easily downloaded from various websites under the guise of a useful application. Today, adware for macOS is also rather common. For instance, Trojan.Yontoo.1 gets onto a Mac, if the user agrees to download and install a browser plug-in from certain sites, or downloads it under the guise of a media player, a program to improve video playback quality, a "download accelerator", etc.
There are also e-mail and removable data storage devices—the traditional media that spread malware with no regard to the operating system.
It is a botnet of infected Macs which took shape with emergence of the Trojan Mac.Iservice in January 2009. To date, it has several thousand computers and has managed to manifest itself in a number of DDoS-attacks.
For evaluation purposes, you can use the trial version. Download the distribution from Doctor Web's site at download.drweb.com/demoreq. The period of a demo license is 30 days.
You can also use the free scanner Dr.Web Light for macOS. The scanner incorporates state-of-the-art technologies to detect and eliminate viruses. You can use it to check your system, whenever you need to. However, Dr.Web for macOS is a more feature-packed product as compared with Dr.Web Light for macOS. It includes Dr.Web SpIDer Guard file monitor to scan files in real time.
According to the documentation, OS X 10.7 and above are supported.
Dr.Web for for macOS protects against viruses whose definitions are present in the Dr.Web virus database. They can be written to infect macOS as well as other platforms.
The non-signature detection technology Origins Tracing and heuristic analyser help neutralise threats yet unknown.
