If you look closely most of the detections are related to NirCmd
, a command-line utility that allows writing to and deletion of values and keys in the registry and is used (embedded) in some specialized fix tools like Combofix. Other common detections include process.exe
, and catchme.exe
Certain embedded files that are part of legitimate programs or specialized fix tools such as Combofix may at times be detected by some anti-virus and anti-malware scanners as a "Risk Tool
", "Hacking Tool
", "Potentially Unwanted Program
", or even "Malware
" (virus/trojan) when that is not the case
. This occurs for a variety of reasons to include the tool's compiler, the files it uses, whether files are compressed
, what behavior it performs, any registry strings it may contain and the type of security engine that was used during the scan. Other legitimate files which may be encrypted or password protected do not allow access for scanning but can be detected as a threat.
Such programs have legitimate uses in contexts where a Malware Removal Expert asked you to use the tool or when an authorized user/administrator has knowingly installed it. When flagged by an anti-virus or security scanner, it's because the program includes features, behavior or files that appear suspicious or which can potentially be used for malicious purposes. These detections do not necessarily mean the file is malware or a bad program.
It means it has the potential for being misused by others or that it was simply detected as suspicious or a threat due to the security program's heuristic analysis
engine which provides the ability to detect possible new variants of malware
. Anti-virus scanners cannot distinguish
between "good" and "malicious" use of such programs, therefore they may alert you or even automatically remove
them. In these cases the detection is a "false positive
The problem is really with the anti-vendors who keep targeting these embedded files and NOT with ComboFix. As elise025
said, we can inform the developer but he has encountered this issue before and in most cases there isn't much he can do about it.
