Worm:Win32/Dorkbot.A Description

Worm:Win32/Dorkbot.A, a variant of the well-known Dorkbot family of worms, includes the standard backdoor-based attacks of its kindred, which can be used to compromise your computer's privacy and security to the point of allowing criminals near-total control over your PC. Also like its kin, Worm:Win32/Dorkbot.A has been found to use many different methods of distributing itself. Some of the major methods that SpywareRemove.com malware experts have outlined include spam on social networking sites, drive-by-download browser exploits, instant message spambots and Autorun exploits on removable drives. Because Worm:Win32/Dorkbot.A aims to compromise your PC for the purpose of granting criminals to command and earn from it, you should remove any Worm:Win32/Dorkbot.A infection immediately with anti-malware programs that can be certain of detecting all copies of Worm:Win32/Dorkbot.A (which, like most worms, will create backups of itself).

The Anything But Dorky Capabilities of Worm:Win32/Dorkbot.A

Worm:Win32/Dorkbot.A doesn't show any obvious symptoms of its attacks, but like a standard backdoor Trojan, Worm:Win32/Dorkbot.A is capable of enacting significant system changes that bring your PC's security down to rock-bottom levels. Worm:Win32/Dorkbot.A's primary file uses a semi-random name, and SpywareRemove.com malware researchers note that Worm:Win32/Dorkbot.A also uses basic Registry exploits to enable itself to launch automatically along with Windows. In lieu of displaying its own memory processes, Worm:Win32/Dorkbot.A will inject its code into normal Windows processes, with the amount of processes affected partially dependent on whether or not the Worm:Win32/Dorkbot.A-compromised Windows account has admin privileges.

Worm:Win32/Dorkbot.A then makes contact with an IRC server to receive additional commands. Some of the attacks that SpywareRemove.com malware experts have noted in a Worm:Win32/Dorkbot.A infection include:

  • Collecting and transmitting basic system information (such as your OS version) that could be used to enable other attacks.
  • Stealing sensitive information such as browser-stored passwords or passwords from FTP clients.
  • Blocking functions (such as file deletion) when they're used to identify and remove any of Worm:Win32/Dorkbot.A's components.
  • Block your browser's ability to access security-oriented sites.
  • Altering the files of system utilities like the Registry Editor, Task Manager or Command Prompt.

Of course, Worm:Win32/Dorkbot.A also can install other malware that may include additional attacks besides the ones noted in this list.

The Struggle to Keep the Dorkbot Parasite out of Your PC

Given the earlier list of its functions, it should be obvious that Worm:Win32/Dorkbot.A is bad news, SpywareRemove.com malware researchers note that it can be difficult to avoid a Worm:Win32/Dorkbot.A infection in the first place. Worm:Win32/Dorkbot.A has been found to use many different methods of distribution. Some, such as the Autorun exploit that lets Worm:Win32/Dorkbot.A spread from a removable drive-based device to another PC, are old and have been combated with appropriate security patches. Others, such as Worm:Win32/Dorkbot.A's ability to use drive-by-download exploits on compromised sites to install itself automatically, still are very modern and difficult to detect.

Web browser security is one of the most important general safety measures for avoiding Worm:Win32/Dorkbot.A's many infection vectors. SpywareRemove.com malware experts recommend disabling exploitable browser features (in particular, Java), avoiding suspicious links that may have ties to spambots and keeping all software on your PC completely updated.

Because Worm:Win32/Dorkbot.A isn't designed to display symptoms, the only evidence of a Worm:Win32/Dorkbot.A attack may be the alerts from your anti-malware software. Likewise, anti-malware software should be used whenever you need to remove Worm:Win32/Dorkbot.A from your PC.
