Trojan.ADH.SMH is a heuristic detection that has been applied to some forms of adware, high-level threats like banking Trojans and, in some cases, innocent, legitimate applications. Since there is a broad variability in the types of programs detected by the label of Trojan.ADH.SMH, malware researchers recommend using the most accurate and updated security solutions available to determine the proper response to Trojan.ADH.SMH. Until you can assure the safety of the affected PC, you also should take care to protect passwords and other information that are most likely to be stolen by some variants of Trojan.ADH.SMH, such as Zeus.

Trojan.ADH.SMH: the Trojan that Comes in Threes

Ideally, anti-malware utilities always would detect threatening software according to specific definitions and identifies. However, this sometimes isn't possible, which has led to the development of heuristic labels that identify software that engages in 'suspicious' activities, such as injecting itself into another program's memory process. Trojan.ADH.SMH is one of these labels and has been seen in major use against advertising add-ons, Trojans that compromise bank accounts and even, by mistake, non-threatening products. The technical term for the latter is a 'false positive,' which malware experts recommend reporting to the associated security company. In the meantime, false positive versions of Trojan.ADH.SMH may be white-listed to allow the associated program to function, until corrections can be made to your security software's database.

Trojan.ADH.SMH's two, most common threatening variants are defined as follows:

  • Some versions of the Crossrider-based adware may appear as Trojan.ADH.SMH, due to their interferences with your Web browser's usual functions. Invariably, these interferences are observable as unwanted advertisements, which may be security risks that expose you to online threats. ElectroLyrics and Savings Hero are two examples of this adware.
  • Trojan.ADH.SMH also has been applied to some versions of Zbot, AKA Trojan Zeus or ZeuS. This banking Trojan monitors your online transactions and attempts to compromise any accessible bank accounts, and may modify a Web page's contents before collecting any information that's transferred through it. Other, non-bank accounts also are at high risk of being compromised by this variant of Trojan.ADH.SMH.

Knowing When to Protect Yourself from Trojan.ADH.SMH and When to Relax

Potentially inaccurate threat detections always require a certain degree of common sense to resolve. If you keep your anti-malware tools up-to-date, inaccurate warnings for Trojan.ADH.SMH and other threats should be minimal. If you are sure that the program accused is uninfected, you can report a false positive of Trojan.ADH.SMH, but this always should be verified by third-party anti-malware tools.

However, Trojan.ADH.SMH also may encompass high-level PC threats that include multiple components and even rootkit technology. Removing these genuinely threatening versions of Trojan.ADH.SMH is necessary for the safety of your PC and all of its users. You should use appropriate anti-malware techniques, such as switching to Safe Mode to scan your PC, always is recommended whenever there are doubts surrounding a new Trojan detection.
