Just installed the latest version of ccleaner a maintenance utility that's been popular with users here for many years. Now you may or may not be aware that Piriform the writers were purchased earlier this year by avast! the antivirus company. Which brings me to the problem, having installed the latest ccleaner I get popups telling me my security is disabled followed shortly by a note that avast! is now handling my security. This was a bit of a surprise as at no point in the download was avast! mentioned and at no time did I authorise its installation. I look on the website check the news sections and read the bit outlining the improvements to ccleaner. Nowhere is there the slightest reference to avast!
To my mind this is a sneaky underhand way of foisting your product on unsuspecting users and if this is the way they intend to operate please consider all my prior recommendations for both these programs:
at a guess even turned off I assume the system has Panda registered as being installed as security this being enough to disable the avast! install. I've checked with somebody else who had the same issue and he also was using Defender as AV.
Now I could install a new AV on the laptop and check things out again but to be honest I can't be bovered.
