Dr.Web CureIt! vs. Dr.Web Anti-virus
The anti-virus keeps reporting that a Trojan has been detected on one of our PCs.
We started the Dr.Web scanner, but it hasn't been able to find anything.
We also tried Dr.Web CureIt! and Dr.Web LiveCD with the same result.
After we do a system restart, Dr.Web notifies us again that a Trojan has been detected.
Please help me resolve this issue.

The myth about Dr.Web CureIt! being far superior to Dr.Web anti-viruses for desktops just won't die, despite the numerous refutations we’ve published.
It is important to note that Dr.Web CureIt! is a specific Dr.Web anti-virus scanner build. The very same scanner is included in Dr.Web Security Space, Dr.Web Anti-virus, and Dr.Web Enterprise Security Suite. They all use the same virus database.
But what makes the utility so special? Well, it will run on any machine, and it doesn't need to be configured. Of course, the utility does save its files on the computer that it’s being run on (and it can be launched again from the corresponding directory). Unlike products providing resident anti-virus protection, Dr.Web CureIt! requires neither registration nor installation.
Because the utility, which can be downloaded from Doctor Web's site, always incorporates up-to-date virus databases, Dr.Web CureIt! can be used effectively even on computers with no connection to the Internet or any other network.
That's why the utility may appear to be more effective. A system can get infected after a threat has been analysed and addressed with a virus database update because the anti-virus on the computer hasn't managed to download the update yet. And since the utility comes with the latest virus definitions, it will appear to be more effectual.
And users' actions help maintain the myth too. We often mention that administrators fail to update the security software they use. Apparently, they assume that an anti-virus can use special tricks to learn about new threats. The outcome is quite predictable:
The anti-virus hasn't been updated for quite some time—the last time was in early June 2018. And a full scan was run using outdated virus databases. The latest Dr.Web CureIt! build only conducted an express scan.
The anti-virus hasn't been updated for over a month! Of course, it won't be able to expose the latest threats.
And what will happen if we launch the utility on a computer after the anti-virus has been updated?
The scanner can't detect the file because the SpIDer Guard file monitor (part of the installed anti-virus) already removed the malware before the scanner/Dr.Web CureIt! was launched.
A conventional Dr.Web Anti-virus will always operate more effectively (unless certain system areas have been excluded from scanning).
- You need to keep your anti-virus software up to date. The more often you download updates, the more reliable your anti-virus will be.
- Use the latest version of your anti-virus. If you don’t, something like this can even happen: "This problem occurred because you used an obsolete distribution file to install the anti-virus. It is incompatible with the updates that have been released for your Windows version this year".
Where do people download these distributions from?
- If you have reason to believe that your system is infected, update the anti-virus to its latest version and run a full system scan.
- Don't forget to reboot the system to apply updates!
