Categories:

Description:
Win32.Downloader.dequ installs several files to the system. It creates autorun entries, scheduled tasks and deactivates user access to explorer, task manager and registry editor. Security and antimalware software are hindered from running. Win32.Downloader.dequ modifies copies of itself to avoid detection. It also infects all installed programs, thus all programs need to be reinstalled after cleaning.
