Obviously not, please read before saying anything.
Most people nowadays do not know much about virus detections, false positives and how to actually use VirusTotal, so here is the short explanation.
None of the packs contain viruses.
All paid and free packs do not contain any malicious code that will cause any harm to your PC. The free pack can be flagged due to the nature of the product, because it changes a lot of settings and applies various commands which can raise red flags to antivirus programs.
To get rid of these detections we would have to sacrifice functionality, which we do not want to do.
VirusTotal false detection
Currently, only the free packs may be flagged as a PUA (Potentially Unwanted Application), not as any form of malware. On VirusTotal you can check the behavior tab and see that under detections no malicious code is detected, which means it is completely safe to use.
Our goal is to be the number one PC tweaking service and we will not get there by adding harmful programs into our tools, since that would destroy our reputation and cause legal trouble.
