Worm:Win32/Gamarue.I is a variant of the Gamarue worm that installs other malicious software onto your computer. Both spam e-mail messages and infected removable drives can be infection vectors for Worm:Win32/Gamarue.I, which is capable of creating new copies of itself and enabling these copies to launch on fresh computers automatically. Because Worm:Win32/Gamarue.I includes some advanced system changes and will conceal its components within normal Windows processes, SpywareRemove.com malware research team recommends that you use anti-malware programs to delete Worm:Win32/Gamarue.I – and, preferably, with a sufficiently in-depth scan that you can catch all copies of Worm:Win32/Gamarue.I, including those that are concealed on your PC's removable drives.

Worm:Win32/Gamarue.I: a File with Unexpected Consequences Once You Open It

While other PC threats may, as always, install Worm:Win32/Gamarue.I without your permission, Worm:Win32/Gamarue.I usually infects new PCs via either e-mail, network-shared drives or removable drives. Malware researchers have examined these infection vectors as follows:

  • E-mail spam may include installers for Worm:Win32/Gamarue.I. These installers will be disguised as supposedly beneficial files, but when launched, will continue through Worm:Win32/Gamarue.I's hidden installation process.
  • Worm:Win32/Gamarue.I also is capable of copying itself to removable devices, such as writable CDs or your USB thumb drive. SpywareRemove.com malware experts warn that, if the Autorun feature is enabled, Worm:Win32/Gamarue.I will be able to install itself on any new PC that shares these devices. However, if this feature is disabled, Worm:Win32/Gamarue.I will not be installed until you launch one of its components: a fake 'usb drive' LNK file.
  • If you share locations of your hard drive over a local network, PCs that access this network also are in danger of being infected by copies of Worm:Win32/Gamarue.I. The infection procedures are identical to those abused in Worm:Win32/Gamarue.I's removable drive-based attack.

Worm:Win32/Gamarue.I changes the Registry in ways that allow Worm:Win32/Gamarue.I to launch with Windows. Worm:Win32/Gamarue.I also is a multiple-component worm that conceals many of its files with misleading names and injects others into the memory processes of normal Windows components. This allows Worm:Win32/Gamarue.I to hide itself from any chance of visual inspection.

The Unpleasant Contents of the Conversation When Worm:Win32/Gamarue.I Calls Home

Once Worm:Win32/Gamarue.I has successfully infected a new PC, Worm:Win32/Gamarue.I attempts to communicate with a remote server and report the infection. Afterward, Worm:Win32/Gamarue.I may use this server to install other types of malware, with potential payloads including rogue anti-malware programs, browser hijackers, spyware and other PC threats.

Because Worm:Win32/Gamarue.I can create duplicates of itself and conceal these copies in a variety of locations, SpywareRemove.com malware research team particularly recommends that you use thorough anti-malware scans for removing Worm:Win32/Gamarue.I infections from your computer. Original versions of Worm:Win32/Gamarue.I were detected as long ago as the middle of last year, but new variants of Worm:Win32/Gamarue.I also have been spotted very recently. Updated anti-malware products, therefore, should be considered essential for identifying and removing Worm:Win32/Gamarue.I completely.
