I am a computer engineer. I am here to confirm without a doubt that Avast, or malware masquerading as Avast has in fact self-installed.
It is likely the real deal Avast as it installed right after I updated and ran CCleaner. I ALWAYS do advanced installs because you're stupid if you don't. There was nothing in the details or fine print about Avast infecting my computer.
I say "infecting" because that is exactly what it is. Like most people in my field, I disable all forms of anti-virus and Firewalls as soon as I buy a PC with Windows pre-installed.
Of all the garbagey, useless f*cking sorry gimmicky so-called anti-virus programs out there conning average users into using their sh*tty services, Avast stands alone as the absolute worst, and you are a f*cking tool if you use it.
Not only am I unable to uninstall or force it closed, as my Admin privileges have been revoked courtesy of Avast. I cannot even access my own programs menu.
Now I have 2 choices, I can waste part of my day eradicating this virus from my machine or I can install the only good malware software on the market (Malwarebytes) and let them take care of it for me. I am choosing the latter.
I will tell you what I'm not gonna do though, I am not installing more Avast software to get rid of the Avast software already infecting me. So you can suck mine and everyone else's c*cks who were lured here by Avast's malicious practices.
I would not wipe my sh*tty ass with anything produced or owned by Avast, and am sorry to hear about Piriform whose products used to be good until the day Avast bought them apparently. I am ceasing the use of CCleaner, Speccy, Recuva, all of it immediately and suggest anyone else finding themselves on this forum do exactly the same. There are better programs out there anyway in 2018, CCleaner is not the only option like it once was.
