From the link that argus posted which you should have perused –
These tools have been carefully created and tested by security experts so if your anti-virus or anti-malware program flags them as malware, the detection is what's known as a "False Positive". 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 removal of these files can have "unpredictable results" and unintentional results.
