I ran SOPHOS and had two alerts one for NirCmd that stated "the unwanted application NirCMD has been detected.  You can try to remove it manually or you can ask SOPHOS Home administrator to add it as an exception..."  SOPHOS also found "OpenCandy" and I cleaned it.

 

Should I be concerned about the NirCmd?

 

Thank you for any advice in advance.

NirCmd by Nir Sofer is safe.

NirSoft is a reputable company and has been around for years. They offer many free utilities and tools which are quite useful. However, some of their program's embedded files may at times be detected by some anti-virus and anti-malware scanners as suspicious, a Risk Tool, Hacking Tool, Potentially Unwanted Program, a possible threat 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, packed, or obfuscated to protect code, what behavior (routines, scripts, etc) 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 in order to conceal itself so they do not allow access for scanning often trigger alerts by anti-virus software.

For example, a common detection occurs with NirCmd, a command-line utility that allows writing to and deletion of values and keys in the registry and is used in some specialized fix tools like Combofix. Password utilities, product keys and many other similar legitimate nirsoft programs have such issues with security scanners - See Antivirus "False Positive" Problems.

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 malicious 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" and can be ignored. I use many NirSoft tools myself and that's what I do when they are detected.
