Can't install CCleaner - Windows 10

Long-time user....

MalwareBytes and BitDefender quarantined Piriform Trojans,

Bitdefender detected Trojan.PRForm.A:

  • "Bitdefender moved a threat to quarantine. File name: c:\windows\system32\tasks\ccleanerskipuac. It is recommended that you run a System Scan to make sure your system is clean."
  • "Bitdefender moved a threat to quarantine. File name: c:\program files\ccleaner\ccleaner.exe. It is recommended that you run a System Scan to make sure your system is clean."

MalwareBytes detected Trojan.Floxif.Trace

I uninstalled 5.33 version, downloaded 5.35 from Builds page, however installer errors out. Piriform's troubleshooting installation guide's first image is the exact message I receive.

I have Admin rights and I don't visibly see BitDefender blocking the 5.35 install.

Not sure what to do, help appreciated.

Download the portable version from piriform.com/ccleaner/builds

Copy ccleaner.exe and ccleaner64 from the zip file to your installation path for ccleaner (usually c:\program files\ccleaner), this will require admin account a uac confirmation depending on your pc's uac setting. if it gets stuck trying to overwrite one of the files delete the file (again admin and/or uac) and tell the copy to retry

Downloading advice worked with one exception. For some reason CCleaner.exe still remains in the default folder (as mentioned below). Even though I have admin rights, I can not delete that file nor folder.

As a workaround, i created a new CCleaner directory\folder and proceeded to install 5.35 w/o issue.
