How to clean an infected Windows PC:  A guide, plus advice needed.

Always have a clean backup system with the latest Antivirus handy that is set NOT to automatically run any media that is connected to it. Pull the HDD/SSD on infected machine use cable/enclosure connect to clean system and procceed to clean. The programs you mentioned are all usefull in there particular way just make sure you only have one running at a time or you can get false positives. I dont clean machines like i used to, but another safer way that only let one program run at a time is Hirens boot CD running on the clean system and connecting hdd/ssd. You can create a custom Hirens CD and boot to from infected machine and clean straight from CD. Also, BleepingComputer.com has everything you need plus tutorials for beginners.

How do YOU clean an infected Windows PC?

I format the disk and install Linux on it. :smiling_imp:

AgentSteel · 2018-03-21T20:22:56.000Z

What I do when I’m too lazy to format / reinstall Windows AND the system is seriously infected :

offline disinfection (boot your system with an antivirus boot CD or usb drive)
boot system and run another stand-alone disinfection tool (DrWeb CureIt generally works OK for me)
install a good AV

Basically a 2-stage disinfection.

If there’s still some malicious crap after that, then :person_facepalming:

Also all my personal computers run Linux :smiling_imp:

Using NOD32 I didn’t have infection since a few years.
Not browsing porn or warez sites helps a lot xD

My mom doesn't browse that kinda stuff; I think she opened an infected email link.

She's usually pretty good at avoiding infections, but she's not perfect.

I, on the other hand, browse some dangerous sites, but I claim that I know what I'm doing.

I haven't had an infection in years, so maybe I'm right.

Sure, but that’s only because I wouldn’t be using my computer at all!

Give it a shot of antibiotics.

All of the tools you’ve listed about work well for me and have done so for years; however, I tend to find that to give it a really good clean you need to take out the hard drive(s) from the system and manually clean them. It usually takes a couple of hours so I make sure that my schedule is clear. I will use the room with the least dust and close the door so that no more dust can be introduced. First of all I’ll take the drive out and use a precision screwdriver to undo the screws of the drive unit. Once the cover is off I set it to one side and wipe my fingers to get rid of the dust on them. I then carefully disassemble the actuator assembly and then the spindle, which now gives me free access to the platters… This is where we really get to work. I will then clean the platters using Brasso and a soft microfibre cloth. If there is a lot of malware then after use Brasso I will then also put the platters into a lint free pouch and put it into the washing machine on a very gentle cycle - I only use nonbio for platters. Once all of this is done I will reassemble the unit, making sure to use a straw as I’m just about to close the unit to recreate the hermetic environment they were in. SSDs are much easier to be cleaned and I simply use a diluted mixture of lemon juice, avacado, and greek yoghurt.

Hillary uses bleach.

Anyone ever seen this take over screen before?

I find that usually one certain antivirus software will work better for getting rid of unwanted guest.
But it’s usually depends on which type of virus, hitchhiker or trojan you get.
Seems that some software company’s specialize in different problems. I have always kind of thought to myself, that it wouldn’t be to hard for some of these company’s to release this stuff through back channels so that they could profit from the fix.
Just my two cents.

I have not seen that...

Looks like a scam.

That used to be my number 1 go to software, but eventually it just wouldn’t get the job done sometimes. It take some other software to clean it up and sometimes another.
Yeah, the “your computer has been locked” It is a scam.

Ever since my IT guy told me to use sandboxIE I havent had any problems.

For the troubled customers, (The ones you keep telling them to not let the fake Microsoft scammers get on your computer and lock down the PC with a Syskey password) We reinstall Windows, Install DeepFreeze By Faronics and setup an unfrozen partition so the customer is able to work on data/install programs. If they get a virus it won’t matter. Just reboot the computer and it cleans the slate. It’s a big F-U to the fake Microsoft scammers out there.

I’ve see a few variants of this. Including versions that speak in different languages, some that use your webcam and snap a picture of your face to instill the fear of implication even further. It’s amazing how many un-savvy internet users are out there. I make money off customers this way. Some learn from the mistakes they make, some do not.

Bottom line is, you can avoid all of this crap. Don’t go to B.S. websites. Stick to legit sites. If you get an unknown popup, don’t click on it. Kill your browser with the task manager. If you get a email, check the email address. You know it’s fake if it claims its supportchasebank@chace.lt.com <— red flag.

I’ve never had a virus on my computers as I know what to avoid and only visit legitimate websites.

I used Kaspersky, Anti MalwareBytes and Spybot - Search & Destroy. Got rid of everything with these. But usually using your common sense helps to avoid malware in the first place.

I haven’t used Spybot in a while.

Thanks for the tip!

Oh, and my computers rarely get infected.

I’m working on my mom’s computer, and I’ve tried all of my favorite programs, and it’s still infected.

A few effective programs for removing malware and viruses:

Hitman Pro

Kaspersky Anti-Virus
