Rootkit.Boot.STT.a Description

Rootkit.Boot.STT.a is a rootkit that's often associated with the presence of rogue anti-malware products and PC threats that infect removable drives (such as worms). Rootkit.Boot.STT.a is still actively-distributed, although symptoms of Rootkit.Boot.STT.a attacks may not always readily visible. Like other rootkits, Rootkit.Boot.STT.a compromises your operating system's integrity to conceal itself, and malware research team recommends that you use advanced anti-malware software to detect and delete Rootkit.Boot.STT.a without damaging your computer. Rootkit.Boot.STT.a also has a high probability of conducting attacks that use a significant amount of the infected PC's resources (by recruiting your PC into a botnet, using keylogging functions, etc), and these hidden functions can correspond to a noticeable degradation of your OS's performance until Rootkit.Boot.STT.a is removed.

Rootkit.Boot.STT.a – the Monkey in Your PC without an Obvious Cause

While Rootkit.Boot.STT.a is designed to avoid overt symptoms of its presence and attacks, Rootkit.Boot.STT.a's payload has often been noted to cause a range of minor but independently-detectable symptoms that anyone can notice. While malware experts note that relying on manual detection of these symptoms isn't a substitute for appropriate rootkit-detecting software, symptoms of Rootkit.Boot.STT.a's attacks have been known to include:

  • Browser redirects that promote irrelevant advertisements or potentially malicious sites; particularly sites that are related to rogue anti-malware software such as fake anti-virus scanners.
  • Poor system performance that causes instability in unrelated programs, including a noticeable overall slowdown of your operating system.
  • Unwanted changes to your desktop or start menu, such as additional shortcuts or removed shortcuts.
  • Random system crashes (in Windows, well-known as the notorious Blue Screen of Death or BSOD).
  • Problems with accessing infected directories, especially your Windows\system32 folder.
  • Error messages related to infected USB flash drives, such as alerts that claim that the device is in use even if you're not using it.

The Risk of Rootkit.Boot.STT.a to Windows Users

Rootkit.Boot.STT.a has been confirmed to be able to affect XP versions of Windows even if they have the latest Service Pack (SP3), although malware analysts haven't been able to confirm Rootkit.Boot.STT.a for other versions of Windows just yet. Despite this, it's not recommended that you avoid updating to SP3, since that Service Pack does close security exploits that are related to other PC threats. However, as a recently-distributed PC threat, Rootkit.Boot.STT.a should be considered a potential danger even for modern versions of that platform such as Windows 7.

Since PC threats related to Rootkit.Boot.STT.a have a good chance of infecting removable USB drives, malware experts advise against sharing such devices with other PCs until they've been disinfected. Of course, you should also delete Rootkit.Boot.STT.a with any necessary brand of anti-malware scanner, since Rootkit.Boot.STT.a's presence is a security threat that can be used to install or protect other types of malignant software.
