Both are aimed at keeping the anti-virus current to protect a computer against any and all threats, including the latest ones. The difference is that when only the virus databases are updated, you don’t need to reboot the system, but when the anti-virus components are updated, rebooting may often be necessary. We strongly recommend that you act on Dr.Web reboot notifications related to component updates because out-of-sequence updating may lead to a weakening of protection.
Rebooting is needed so that the updated Dr.Web drivers work properly with the operating system. Our competitors’ anti-virus solutions are updated in the same manner.
Doctor Web strives to release Dr.Web component updates, especially critical ones, as quickly as possible. After all, the reliability of the protection directly depends on the anti-virus’s ability to intercept and cure the latest threats and still operate error free. Experience shows that for each individual product, updates that require a reboot are being released no more than once or twice a month, the only exception to this being recently released program versions and those under active development.
In the window that notifies users that a reboot is required, you can choose when you want the system rebooted. You can choose to do it now or postpone it until a time convenient for you.
Just one Dr.Web database entry can lead to the detection of tens, or hundreds, or sometimes even thousands of similar viruses.
Moreover, the presence of Origins Tracing™ and structural entropy analysis in the Dr.Web anti-virus makes it possible to detect malicious programs that are so new they have yet to undergo analysis in the Doctor Web anti-virus laboratory.
The smaller number of virus entries (compared to some other anti-virus programs) even makes it possible to detect unknown viruses (i.e., those not in the virus database) with a high degree of certainty. These are viruses that will be created on the basis of existing viruses.
How do users benefit from the small size of the virus database and the fewer number of entries in it?
Thus, the fundamental difference between the Dr.Web virus databases and the virus databases of other anti-virus programs is that with its fewer number of database entries, the Dr.Web database allows as many (or even more) viruses and malicious programs to be detected.
Virus databases do indeed get larger with each update. But Dr.Web solutions use the most cutting-edge anti-virus database format so that as the virus databases get bigger, scan speed is not reduced.
Moreover, because the latest technologies are applied to Dr.Web solutions, the size of the virus databases can be reduced. This is because they exclude entries containing information about malicious programs that are automatically detected with the help of the newest technologies.
When an Internet connection is present, the anti-virus updates every 30 minutes by default (this is the most optimal setting).
When required, you can change this setting by doing the following: right-click on the Dr.Web icon located in the bottom-right corner of the system tray. Then, in the context menu, select Tools → Settings and go to the Updating tab.
Alternatively, you can update the anti-virus manually by right-clicking on the Dr.Web icon in the bottom-right corner of the system tray, and then selecting Updating in the context menu.
No, that’s not true. When you buy the anti-virus, you are paying not only for the program itself, but also for the right to get anti-virus database and module updates as well as the opportunity to contact the technical support service while your license is valid. Nobody will ever come after you for additional money! Proof of this can be found in the Dr.Web license agreement which you are invited to read before you install the anti-virus. Doctor Web assumes a number of obligations and guarantees the following:
‘Throughout the entire software usage period, the User is granted the right to receive through the Internet virus database updates as well as upgrades of the software modules as they are made available by the Rights Holder’.
The Dr.Web license agreement is a legal document that guarantees your rights as a consumer.
Hundreds of thousands of new viruses appear DAILY — and correspondingly, tens of thousands appear every hour. The overwhelming majority of them are modifications—brothers and sisters of existing viruses. Yes, the Dr.Web heuristic analyser and the Dr.Web behavioural analyser really do make it possible to detect with a high degree of probability that a file has been infected or is a Trojan itself. But “probably infected” does not mean “infected for sure”! This file will be declared a virus only after its virus signature has been added to the Dr.Web virus database.
But no anti-virus software vendor will ever guarantee you that today won’t be the day that somebody writes a brand new virus that can’t be detected by even the most perfect heuristic analyser.
As a rule, malicious programs reach their victims at the same time they reach the Doctor Web anti-virus laboratory for analysis, and in the case of the newest malicious programs (those not yet detected by any available mechanism), anti-virus analysts need time to develop and test a “cure”. Frequent updating makes it possible to minimise the time it takes for potential victims of criminal attacks to get hold of updates. Often ‘cures’ for malicious files are available, but have not yet been downloaded.
Unlike its competitors, Doctor Web’s principled position is to release updates as frequently as possible so as to minimise the time period during which new threats can pose a danger.
That is why the anti-virus databases need to be updated every time the computer is connected to the Internet or as frequently as possible if the connection is continuous.
First do the following:
If after trying the above, you are still experiencing difficulties, please contact the Doctor Web technical support service and describe in detail how your computer connects to the Internet (note: if a proxy server is involved, please specify whether authentication is required, and whether your browser or Dr.Web update module is configured to be used via the proxy server).
Anti-virus update downloads can include updated anti-virus databases as well as application files. In the latter case, a system restart may be required to apply the update. And in this case, the corresponding notification will appear.
The user can restart the system immediately—by closing all the running applications and pressing the Restart now button. They can also make the anti-virus show the notification later or schedule a system restart. To use either of the two latter options, first select Remind me later.
You can set the reboot time to occur within the next 24 hours.
Users are also able to restart the system on their own whenever they want. For example, go to Start → Shut down or sign out→ Restart/Shut down.
Important! Selecting the option to enter sleep mode or switching user accounts won't restart the system so that the pending updates are applied.
Important! Pressing the power button on a tablet or laptop will make the device enter sleep mode. To apply updates, restart the system using any of the available methods (including the restart option in the anti-virus notification pop-up).
