What is Ransomware? and Ransom ware attack? How to be safe and Identify its attack?
What is Ransomware ?There are two types of ransomware :
A : Lockscreen Ransomware (old version)
B: Encryption Ransomware (new version).
A : Lockscreen Ransomware (old version) :Lockscreen ransomware shows a full-screen message that prevents you from accessing your PC or files. It says you have to pay money (a “ransom”) to get access to your PC again.
B: Encryption Ransomware (new version):Encryption ransomware changes your files so you can’t open them. It does this by encrypting the files – see the Details for enterprises section if you’re interested in the technologies and techniques we’ve seen.
Older versions of ransom usually claim you have done something illegal with your PC, and that you are being fined by a police force or government agency.
These claims are false. It is a scare tactic designed to make you pay the money without telling anyone who might be able to restore your PC.
Newer versions encrypt the files on your PC so you can’t access them, and then simply demand money to restore your files.
How you can get it in your PC / Laptop or Computer ?Ransomware can get on your PC from nearly any source that any other malware (including viruses) can come from. This includes:
- Visiting unsafe, suspicious, or fake websites.
- Opening emails and email attachments from people you don’t know, or that you weren’t expecting.
- Clicking on malicious or bad links in emails, Facebook, Twitter, and other social media posts, instant messenger chats, like Skype.
- It can be very difficult to restore your PC after a ransomware attack – especially if it’s infected by encryption ransomware.
- That’s why the best solution to ransomware is to be safe on the Internet and with emails and online chat:
- Don’t click on a link on a webpage, in an email, or in a chat message unless you absolutely trust the page or sender.
- If you’re ever unsure – don’t click it!
- Often fake emails and webpages have bad spelling, or just look unusual. Look out for strange spellings of company names (like “PayePal” instead of “PayPal”) or unusual spaces, symbols, or punctuation (like “iTunesCustomer Service” instead of “iTunes Customer Service”).

Open Task Manager. There are a number of ways you can do this:
Right-click on an empty space on the taskbar and click Task Manager or Start Task Manager.
In the list of Applications or Processes, click on the name of your web browser.
Click End task. If you are asked if you want to wait for the program to respond, click Close the program.
In some workplaces, access to Task Manager may be restricted by your network administrator. Contact your IT department for help.
When you open your web browser again, you may be asked to restore your session. Do not restore your session or you may end up loading the ransomware again.
If your PC is locked?Method 1: Use the Microsoft Safety Scanner in safe mode
First, download a copy of the Microsoft Safety Scanner from a clean, non-infected PC. Copy the downloaded file to a blank USB drive or CD, and then insert it into the infected PC.
Try to restart your PC in safe mode:
In Windows 10
In Windows 8.1
In Windows 7
In Windows Vista
In Windows XP
When you're in safe mode, try to run the Microsoft Safety Scanner.
Method 2: Use Windows Defender Offline
Because ransomware can lock you out of your PC, you might not be able to download or run the Microsoft Safety Scanner. If that happens, you will need to use the free tool Windows Defender Offline. You can download Windows Defender Offline from here.
