CCleaner

Anyone using versions: v5.33.6162 and CCleaner Cloud v1.07.3191 is advised to download new versions.

August's download had been compromised ie, hacked, and contains a potentially malicious bot.

Cheers priscus. Just updated yesterday but good to know.

Run a virus scan, just to make sure that if version 5.33 has previously run, that you have not been left any nasties by it.

Malwarebytes found Trojan: 'Floxif' (potentially dangerous) on two of my machines.

I cannot prove they had been left as a consequence of the toxic payload enabled by the malware in Ccleaner, but it would appear to be the only thing which the two machines have in common, and neither had visited any dodgy sites, or had any unknown material clicked upon.

Thanks again.

Is beginning to make more sense now: someone went to a lot of trouble to try to sneak this through as an undetectable plant.

Although version 5.34 has only been out for a matter of days, (They have been in the habit of updating on a monthly basis) Piriform have released version 5.35.
