Components in Dr.Web 8.0 products for Windows updated

April 24, 2013

Russian anti-virus company Doctor Web has released an update for the Dr.Web Anti-rootkit Service (, the Scanning Engine ( and the file monitor Dr.Web SpIDer Guard ( incorporated in Dr.Web Security Space and Dr.Web Anti-virus 8.0 for Windows.

The scanning service tweaks improve overall performance, accelerate the launch of processes and speed up file scanning. Also, the service no longer needs Windows API to detect system processes, so they can be removed from the list of scanned objects. This significantly increases system boot-up speed and accelerates the launch of trusted applications.

The updated Dr.Web SpIDer Guard can use some Dr.Web Anti-rootkit Service routines and, if necessary, utilize the service to neutralize threats.

The update also resolves known issues to improve the overall stability of Dr.Web Security Space and Dr.Web Anti-virus 8.0 for Windows.

  • An error that could cause a system failure when the Dr.Web Anti-rootkit Service was running has been fixed.
  • Also resolved was a problem involving system files being processed longer than they should have been while removable data storage devices were being initialized at the same time when incorrect settings were being used to establish an Internet connection.
  • A defect keeping the size of the quarantine from resetting after being cleaned has been corrected.
  • Previously, malignant files were being moved to the local disk quarantine from a removable media device even if the option to create the quarantine on a removable media had been enabled; that issue has been fixed.
  • The error message “Access denied or incorrect program usage” was being displayed when Dr.Web was being removed, and that issue has also been rectified.

The update will be performed automatically; however, a system reboot will be required.
