CCleaner Hacked - Was Distributing Malware For A Month Until Discovery
I know some of you use CCleaner and thought you'd want to know.
If you use a 32-bit system and downloaded CCleaner version 5.33 in August or September, you were likely infected with a trojan that is incredibly dangerous and difficult to get rid of.
I downloaded it myself but have a 64-bit system and thus the trojan didn't activate. For me, using Malwarebytes seems to have gotten rid of the problem, but you definitely need to scan your systems.

Thankfully, I only use the 64-bit version. I also scan my system with Malwarebytes every now and then.
But I have to say, my heart skipped a beat when I saw CCleaner trending on Twitter today.

You don't need to use apps like CCleaner.

R8 Yes, you do if you don't want to clean each browser that you use individually, in addition to purging the temporary system files.
It makes a huge difference on older systems.

I use CCleaner more out of habit than anything, but I just uninstalled it after this. It wasn't necessary, you're right, but it was handy.
Even though the trojan I found ("Nyetya") supposedly wasn't doing anything per Security Task Manager, once I removed it and CCleaner after a full Malwarebytes scan and reboot, my PC is working faster. I'd noticed something was causing lag sometimes and I think it may have been this trojan trying to execute. Thank goodness I'm on a 64 bit system.

I need a PC for my online job. Otherwise I wouldn't bother, honestly.

I can't imagine not having a PC. I've never had any problems, and that's way back from Windows 95 times.

If you want to use a tool like CCleaner, it's best used once, and then uninstalled until you need it again. Most apps that are one-use like that should be removed quickly. And be careful of turning on anything that auto-updates in the background - some of the antivirus will update hourly if you let it.
Avast owns CCleaner, so if you use any Avast products, look at them askance as well.

R3 - on macs here. Got 2 viruses this summer. First time I've ever seen that. One was actively fucking things up.

Yeah R3 Mac's "we never get viruses" claim hasn't been true for a number of years.

Considering that Avast Antivirus now owns CCleaner, I can see why they kept hush about it - though it was still the wrong thing for them to do. But it definitely is an egg on their faces. How is anyone to trust them to protect their home computers, when the company can't even protect it's own servers?
