Backdoor:W32/SdBot comprises a large family of remote access utilities known to be used by hackers to gain unauthorized control of a user's computer system.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
Caution: Manual disinfection is a risky process; it is recommended only for advanced users.
Manual disinfection for SDBot backdoor requires renaming of an infected file, usually located in Windows or Windows System folder and restarting a system. Please note that the backdoor's file may have read-only, system and hidden attributes, so Windows Explorer has to be configured to show such files.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First check if your F-Secure security program is using the latest updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note: You need administrative rights to change the settings.
Variants in the SdBot family include:
Based on the variant, SdBot backdoors copy themselves either to the Windows System directory, or to other directories located in the System directory. It also ensures the copy is started when the system stars by creating a subkey in one of the following registry keys:
The name of subkey and its value differ depending on the variant.
SdBot backdoors connect to various IRC servers, joining an IRC channel (the choice of channel is hardcoded into the code) in order to receive instruction from the attacker(s). The backdoor can perform a variety of actions, including acting as an IRC proxy server, downloading and executing remote files, sending messages and more.
