A guy called my home claiming he works for windows/Microsoft.
He showed infected files I had and had software on his computer to be able to control other people’s computer stuff.
He downloaded something to my computer a chat thing.
He also changed my SysKey and he said something like "send me 149 dollars to get a Windows XP upgrade".
I did not send him money luckily.
However although I am in the top 10 most intellegent safety experts on
planet earth, he even had me tricked.
My eMachines windows XP is now unplugged.
Please if you get a call like I did hang up and unplug your computer for about 72 hours but at least 2 hours I recommend.
Also while very very very rare that a scammer means physical harm, please report all scammers especially those who wish to do physical harm to targets.
Naturally the other guy claimed, that I was doing it wrong, but eh.
I came across an interesting article, where I have, for the first time, read and learned something about how scammers operate. This article is about what happens when a scammer, in a twist of fate, calls a security expert!
Tech Support Scammer Cold Calls Emsisoft | Emsisoft Blog (http://blog.emsisoft.com/2014/08/29/what-happens-when-a-tech-support-scammer-cold-calls-a-security-expert/)
If this article is true (I think it is), it is debatable how many levels of scamming professionals there are (probably a lot). You`ll see for yourself what I mean if you read the article.
Incidentally, it is about the same thing the Original Poster was talking about. I recommend reading it to anyone interested, especially OP.
(Emsisoft is, it seems, an anti-everything-bad-on-Internet company (viruses, malware), and while I don`t know how good their software is, they seem like fine people, at least according to their blog)
I like it that these guys are trying to raise awareness about this matter.
