CCleaner question

Welcome back to the forum.

Yes, CCleaner was hacked in both 2017 and 2019. It is to be expected it will be hacked again soon and some say that Avast should retire CCleaner.

CCleaner is not malware, however is open to breaches. So it is up to you what you do with this information.

This is a SPONSERED post that shows some alternatives: {MINITOOL PARTION WIZARD}

There are many existing threads discussing CCleaner - try the forum search box. I don't use or recommend these snake oil apps.

Agreed, there's always Disk Clean-up built into Windows that doesn't have those security risks!

Thanks for the reply James. I'll have a read of your link.

So I prob should haul it off my PC more or less straight away right?

Yes, I would reccommend Cleaning it off your computer

I will remove it. But I am a bit freaked now if I have been 'hacked' or if there is some other dodgy sh*t running in the background as a result of installing this program. Is there any need to be worried about my system? It does seem fine though. All of the things are going through my head like could someone have access to my Gmail, Instagram, Twitter etc. as a result of me having used CCleaner for so long. Even my login for this site for heavens sake! Couldn't actually sleep the other night thinking about it all of that!

Or, is that me just overthinking it? The version is 5.78, and was installed in the first quarter of 2021. But I had been using it for the past few years.

I will have a search through the other threads with CCleaner too.

Run a full virus scan with your AV app and MalwareBytes free version to alleviate your concerns.

Hi Steve, I actually only have the default Windows Defender. I used to use MalwareBytes free but think I read a few years back that installing this can cause issues having more than one antivirus software installed. Or is MalwareBytes definitely a good bet to have installed also?

Hello,
I have WD primary and MalwareBytes free is secondary/manual scan - so it doesn't run automatically or compete with WD.
