All these tools are packed using PECompact (an exe packer) which is also unfortunately used by many of the malicious programs. This is why some of the anti-virus products become suspicious about these tools.
As long as you are downloading them from trusted web sites, you do not have to worry :)

Expanding on what Romeo29 has said.

Certain embedded files that are part of legitimate programs or specialized fix tools, 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 or packed, 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 an authorized user or 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". Either have your anti-virus ignore the detection or temporarily disable it until you run the tool.
