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 obfuscated, encrypted or password protected in order to conceal itself so they do not allow access for scanning but often trigger alerts by anti-virus software.
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. Compressed and packed files in particular are often flagged as suspicious by security software because they have difficulty reading what is inside them. 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-virus vendors who keep targeting these embedded files and NOT with ComboFix
. We can inform the developer but he has encountered this issue many times before and in most cases there isn't much he can do about it. Once the detection is reported to the anti-virus vendor, they are usually quick to fix it by releasing an updated definition database.
But as you have discovered a new version of ComboFix often encounters the same false detection and the cycle begins again. sUBs frequently updates ComboFix and much of his time is involved with doing that in order to keep ahead of the malware writers. The remainder is spent addressing bugs, issues and questions by forum experts helping others with infected computers. He simply does not have the time to submit samples every time he releases a new version of ComboFix.
I understand your frustration but please don't take my reply personal; the developer never intended ComboFix to be used in a large enterprise or business environment.
