Please note the message text in blue
at the top of this forum. No one should be using ComboFix
unless specifically instructed to do so by a Malware Removal Expert who can interpret the logs. It is a powerful tool intended by its creator
to be "used under the guidance and supervision of an expert
. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again.
Please read the pinned topic ComboFix usage, Questions, Help? - Look here
With that said, 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, registry fixes, malware strings it contains and the type of security engine that was used during the scan.
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
". In the scenario you describe, AVG 2011 was falsely detecting it while AVG 9 did not.
