What is the most infected PC you have ever come across?

[ShadowCaptain]

So, yesterday one of my friends texted me like "hey my PC is running slow, any idea why?"

 

Like a knight in shining armour I drove around to their house, ready to to find out the problem, upon boot I am met with at least 4 different fake virus scanners. I open chrome, and about 5 windows pop up, google search has been replaced by iSearch or something and everything takes about 10 years to open

 

I am like... well this is bad but fixable, so a trip to malwarebytes site (about 10 hours later) and I get a scan running

 

within a few minutes the counter gets to 20, and I am like, wow thats a few, after about 10 minutes we are at 500, and after the scan is complete we are at

 

4263 detected files

 

Which is pretty bad though not the worst I have seen (encryption virus is probably the worst) so come on guys, what is the most infected PC you have ever seen

Doing work experience at an IT place soon where they get a lot of old people apparently so im expecting to beat your record soon

Oh that is not a record, that was just what I saw yesterday, still pretty freaking bad

 

After working in a pc store for years with a clinic I have seen worse, including people having had their entire PC encrypted and the hacker trying to ransom their files back to them for £1000 or he would delete the encryption key

My brothers laptop had ~3500 threats, so I cleaned it and I told him not to download games illegally or the pc will break of all the viruses. He has not pirated anything ever since.

[NeatSquidYT]

My friend had a couple of hundred Trojans once on his computer.

[PirateCoffee]

Probably like 20.

[Clyne]

i think my sister had around 12000 threats when she scanned her computer with AVG, she didn't clean it in 2 years. Don't know what she did that got a lot of thrrats.

[Shroomster]

Most in my own pc must be like 7-8 threats. Daily scans at 3 am FTW.

[xNeon]

My friends laptop would barely boot into windows.

I re-installed windows cause I figured it was much faster then dealing with at least twenty malware programs. He was happy with it.

Turns out that was his porn machine. I probably should have figured.

Any computer a teenager has access to, those are the worst.

For now.

For now.

What do you mean with that?

[Semper]

had a client bring in a PC about six months ago (this, my side job posted in my church community newsletter)

Simply cleaning it out took me about 26 hours. About five hours in, I called the client and told him that he was better off just buying a new system, and that the man hours alone needed to be invested in this system would approach the level of a low-end PC. The system was an old Dell Dimension from  2004-ish.

Some of the nastiest stuff i've ever seen, had to clean the system, as the client didn't want to invest in a new OS license (the OEM key had long since been lost), nor invest in a new system.

 

System ran unprotected for most of it's life, I think the grand total came out to about 18k threats.

Took Hitman, JRT, Avast, AVG, Malwarebytes, BitDefender, Spybot S&D, TDSSKiller, Combofix, and CCleaner. to get it back to operable status.

Still not convinced that it's entirely clean (simply because of how long it went unprotected), but it was returned to the owner running significantly better, with the aforementioned disclaimer. Kinda surprised me that Chernobyl hadn't made it on the system somehow.

Probably the last PC that I owned, not sure what it was other than a compaq, but goddamn that thing was fucked from downloading music and aherm.....videos (my high school PC)

[techswede]

An ex friend of mines computer.. 

10.000+ Threats, Incredibly slow even with it being a pretty new 8350 build.. About fifty pop ups when you open a browser, Locked search engine to something i've never heard of before, 

Maybe 10-20 "Fix your computer" programs on startup, Ran a quick (Well.. As quick as it could be) scan and then i pushed the keyboard away from me and told him to buy a copy of windows 

 

I wasn't sure if i should post this since it's more of a horror story than anything else.

The ex friend from the previous story was running an old Sempron system. FM2 sparta or something.

And it had.. issues So i went over there to check it out. 

We started it up. It was extremely loud as always (90 something mm fan on the cpu cooler)

Pretty much the same problems as the system above this. Exept for that there were ads in every single blank space on every page.. It took 30 minutes. I sh*t ye not. to open a browser.

We were prepaired for this though. We brought a new drive since the old one was probably on it's last legs anyways.

So i popped the side panel off.. and..

This is where i got to see what chainsmoking in a closed room with a computer does to it.. You couldn't even see the components

[Fred Castellum]

Ahh it was a 2005 dell laptop when I was working in IT repair. The client had important info that he couldn't lose so we pulled out the hard drive and had another computer scan it, we got around 13k on the anti-virus program(Using AVG at the time). Thats the highest I've ever seen before. 

[flibberdipper]

School computer. It had 46,273 viruses after being run with Symnatec whatever for 5 years. Then my friend downloaded another one while I was still signed in and then nobody could log back on.

[DigitalHermit]

Haven't come across a PC with a severe enough infection...

There was my cousin's laptop which got hit with an avast hijack (not sure if it was publicized and I wasn't able to extract a sample... Basically, the malware mimicked avast's UI making you think it was avast...)I tried to get admin access but it was sealed off, so I nuked the drive and started from scratch...

 

Biological infections (infestation?) though...

I've come across a few PC with a live rat, a cockroach infestation, some garbage, and droppings of something (might've been a rat)... It's an infection of a different kind...

[harrynowl]

We had some business machine where I work running XP that had ~12,000 objects detected in mbam. And about another 40 programs adwcleaner and jrt got rid of.

[TheGamingBarrel]

72,000 In mbam, it took 6 minutes to properly boot and would get tons of pop ups, I cleaned it for them and they are pretty pleased, and also gave them a real antivirus

Not really , Any computer in a non-techsavy persons hands will be bad, and anyone who knows a thing or two will be fine.

Adults can screw up computers if they don't know what's happening as well.

Adults can be worse, trust me

 

I remember a customer bringing his samsung tab 10.1 in to me when I was on the shop floor and hes like "excuse me, how do you close tabs on a tablet, I take it and see that there are like 40 tabs of weird ass porn (freaky shit) ,... I pass it back not wanting to touch it and tell him to hit the little X... he then says "yeah I didnt want to give my 9 year old daughter this back"

 

yeah fuck that,

My friend's laptop came up with 25,542 infected files. Most of the were dodgy installers though.
