Fraudulent Tech Support Call

@scottalanmiller said:
Regular reinstalls, even when things do not break, are a good way of breaking a malware chain for people who have no idea that they are infected... it is just good practice. When malware is a known entity, the importance of breaking that chain gets higher because we don't want to have to assume that the end user is certain when the infection actually happened.
Couldn't you drive yourself crazy thinking you are always infected?
I guess that why products like Deep Freeze are popular.

Also why I am an advocate of having work computers for work stuff and home computers for home stuff.
Nothing of importance gets put on my home computer.

Yeah, that definitely makes sense.
Though it's often tough in very small businesses.
I'll admit to have a ton of personal stuff on my work computer.

@BRRABill Another good way to do it is with VM's and something like virtualbox.

Or VDI on Amazon!

So, if someone really knew what they were doing in the malware world, you don't think they could effectively eradicate the issue enough to make the computer safe?
Places like bleepingcomputer.com for example, where all they do is this stuff every minute of the day.
They look through the files, they figure out what has been done, and they fix it.
Granted, if you have an image, or there is nothing on the machine. Sure, why not just nuke it?
I am talking more specialized systems, or systems where "re-imaging" is not so easy.

Yes. Which is why you don't assume it all of the time. You only assume it after you know that you were compromised when you know the defenses were breached.

They make reckless decisions every day? Definitely avoid them.
Doing deep dives to learn how things work, good. Doing deep dives and pretending that it is a good business design based on the cost/reward or not absolutely dangerous to leave the poor customer with a potentially hijacked machine? Sounds like negligence.
If a local computer shop did this, I'd say you'd have a lawsuit for professional negligence.

How is that cost effective? How is it reliable?

No I mean those websites spend their entire day helping users who have been infected. There is a means to infection. There is a way of reversal.

I would venture to say the sites that do this would have a strong disagreement ... that they do indeed totally disinfect the machine.

Depends.
How much would it cost to backup data, reinstall from media, reinstall the data?

Sure, but there is no means of knowing when it has been reversed. Not only is that a dangerous path to go down, someone with the hubris to think that they can know that they got it is exactly who you don't want doing the procedure.

hubris is the enemy of security. The two cannot be found together.

less that it takes to consider another option.
how much does it cost to have your bank account compromised?

OK, let's take this a step back.
Do you do the same thing with a virus? If WebRoot (hi @nic) finds a virus on your machine and deletes it. Do you also do a total reinstall?
-
-
@scottalanmiller one thing Webroot does if it identifies an unknown as malware is that it rolls back the changes, hopefully saving you the hassle of a reinstall. But I do understand if you want to nuke it from orbit anyway

If it finds one that infected me, absolutely. Every time, no question. I feel like we've asked this before
That seems like a lot of overkill if your AV has caught the virus and stopped it before doing any harm...
