[問題] 我也被勒索了!!該如何查是否有後門程式?

[pageantry (( 人心不古 ))]

其實我已經收到這種勒索信好幾次了，這是從我的智邦生活館的備用信箱寄過來的
也就是收到自己寄給自己的信，當初一直以為系統提醒我要變更密碼
不過最近認真閱讀內容後才發現原來是被勒索了
原本要價是  1000 USD 的比特幣，不過今天這封變成 800 USD 的比特幣

我想當初有可能是透過網球或是NBA的免費直播，
要進入直播前要先點掉廣告而被植入後門程式，
然後這封信開頭就大辣辣把我的信箱密碼帶出來並說明已經取得我的電腦權限
如果我不付錢的話，對方就會惡搞
當然我是不會去付這筆錢的啦!
雖然這是 PC 而非 notebook 所以錄不到我什麼 nasty pictures
不過想知道可以知道或是如何清掉任何存在的後門程式嗎?

(雖然他嚴重警告過我防毒軟體掃不到而且改信箱密碼也無效)

請問有其他的建議嗎?

謝謝

ps.我目前使用免費的紅傘軟體掃描是無異樣.


Some time ago you visited a bunch of adult websites, one of those adult
websites was infected with a backdoor, developed by me. This backdoor
installed itself onto your system, giving me FULL access to all your data,
accounts, contacts, etc.
You can change your passwords but it will not help you, my backdoor will
always grant me full access to your device. Read on and i will tell you how
to close this backdoor.

I have downloaded all your contacts, files, data, etc. From time to time i
also activated your camera and recorded some videos and took some pictures of
you while you "pleased" yourself watching adult content... you know what i
mean.

Now you have 2 options:

Option 1: You ignore this email and i will send all the very nasty pictures
and videos i have of you to ALL your contacts, along with ALL data i have on
you. On top of that my backdoor will lock up your device and you will never
be able to use it again! You probably do not want that, imagine the disgrace!
So read option number 2.

Option 2: I have been watching you for a while now and i want you to
compensate me. To do this please transfer $800 bitcoins to my bitcoin
address: 1L4LYQGhn41ucmNVGc6LAchNy9SP7d15ug (copy/paste this, it's case
sensitive). If you don't know how to use bitcoins just use any search engine
and search "how to buy bitcoins". You can buy bitcoins instantly with your
debit or credit card on many sites.
When you opened this email my system activated a timer. From now you have 8
hours to perform this transaction. When the transaction does not come in
within this time my system will automatically activate option 1, i guess you
don't want that so make the transaction in time and my system will
automatically delete all the data, files, contacts, pictures and videos i
have of you on my server and the backdoor will automatically be closed and
you can go on living your life like this never happened.

I did not target you, you visited the wrong website at the wrong time. I live
in a country where it is impossible to find any job, so i do this to support
my loved ones, think of this as a donation.

Your time is counting!

Good luck.
