Is piriform.com Safe?

See link which supports my findings and/or my current opinion about ccleaner by Piriform (now owned by Avast). http://nordic.businessinsider.com/avast-piriform-ccleaner-hijacked-trojan-malware-2017-9 Sadly I no longer can trust ccleaner after the reported 'inside job' (which seems questionable as to if Piriform was either hacked and/or the company itself had/has someone untrustworthy working there, and/or that Avast itself may be either involved and/or possibly even responsible for the 'irreparable' machine damage that was reportedly handed to Users. And since I can't exclude Avast AV from my suspicions that it seems likely as not that Avast stands/stood to profit from the infected Users , e.g.; once realizing their machine's unacceptable behavior apparently would likely invoke Users into purchasing Avast (as opposed to continuing to run Avast's free AV, assuming that Avast Premium was/is immune to 'ccleaner's malware). So no matter where ccleaner's malware stemmed from, so far as I know, neither company has put up the effort or expertise to resolve the millions of infected machines by offering either a fix or even compensation Users for the time, money and aggravation of wiping once useful and clean machines and painstakingly "clean installing" the OS platform(s), not to mention, all the programs and app's ('simply' to rid our machines of the malware), it's otherwise a sad, sad day that Users (like myself) are finding this out, and not by any (known to me) notices of the 'hacking' and/or the need to wipe and completely re-install, but by sheer luck at running across that article.

Out of all the computer cleaning software developers I can think about, Piriform is the only one that I can trust. Granted, their products DO have a price tag [which usually means nothing good], but they let you use over 75% of their potential without paying a penny. Plus, there is a full fledged privacy policy and their contact info and management team identities are completely open for access under the top's Company menu. Also, the site is not ridden with certificates [just a lone Symantec Trust Seal], which usually means no forged, well, certificates. Rogue computer cleaning software normally is ridden with forged certificates, forces you to pay for it to even work whether you have a credit card or not, and often lack things like contact information.
