I have a license, but Dr.Web does not work
•Make sure that your license period hasn’t expired. To check your license period, go to the License section of Dr.Web main window. If the license expired, buy the new one.
•You may have upgraded the operating system and installed version of Dr.Web does not support the new version of macOS. Uninstall the current version of Dr.Web and reinstall the application. |
Dr.Web freezes or lags
This may be caused by high activity of system processes, which consume a lot of memory resources. Close unused apps to free up some memory. You can view the information and manage running processes with the macOS standard tool Activity monitor.
If the issue persists, try reinstalling the application.
|
Firewall blocked internet access
Create a new rule for the application that can’t get access to the internet in the Firewall preferences.
|
There are no sound alerts although they are enabled
Check the sound volume in System Preferences and on speakers.
|
Preferences are blocked
Preferences of some components are protected. If preferences are unavailable, unlock them. To do that, click at the bottom and enter your user name and password.

Scanning issues
File system scanning does not work (cannot run Scanner or enable SpIDer Guard)
Make sure that your license period hasn’t expired. To check your license period, go to the License section of Dr.Web main window. If the license expired, buy the new one.
|
Dr.Web virus databases take a lot of time to load or the scanning is very slow
•Dr.Web loads virus databases every time it starts scanning or attempts to cure an object. Thus, these operations may take some time.
•Freezes and lags may also be caused by high activity of system processes which consume a lot of memory resources. We recommend you to close unused apps to free up some memory. You can find more information and manage running processes in the macOS standard tool Activity monitor. |
Some files are skipped during scanning
•Files (or folders in which they are contained) may be excluded from the scan.
•Some files may be skipped during scanning because they are corrupted or password-protected or you need administrative rights to access such files. If there are archives in the list of skipped objects, try to unpack them before scanning. |
Scanner freezes
If Scanner freezes, close and restart the application. If the issue persists, reinstall the application.

SpIDer Gate operation issues
SpIDer Gate does not block websites from selected categories
•Make sure that the corresponding category check box is selected on the SpIDer Gate tab.
•If connection to a website was established before SpIDer Gate was enabled, disable and enable SpIDer Gate, then restart the browser.
•Check if the website uses a secure connection (if it does, a lock appears in the browser address bar). If a secure connection is used, select the Scan encrypted traffic check box on the Network tab and restart the browser.
•SpIDer Gate does not block websites that connect through FTP/SPDY or HTTP/2.0. |
Certificate error message appears when opening the website
•This error may occur because some browsers or mail clients do not refer to the system certificate storage while sending and receiving encrypted traffic. In this case, install Doctor Web certificate, which you can obtain by clicking Export button on the Network tab.
•If the browser or mail client was opened immediately after the installation, it might not have obtained the system security certificate. In this case, restart your browser or mail client.
•Original server certificate may be untrusted. To check it, disable SpIDer Gate and restart your browser or mail client. If the error persists, then the certificate is untrusted and we do not recommend that you visit this website. |
SpIDer Gate has blocked the website you need to visit
This website is probably included in the blocked category of websites. To access the website, add it to exclusions.

Update is not loaded

•Make sure that your license period hasn’t expired. To check your license period, go to the License section of Dr.Web main window. If the license expired, buy the new one. |
