Malwares Explained:
Malware is short form of malicious software. It is often software but can also appear in form of script or code. It is often used by malicious elements to in-filtrate, damage or disrupt computer operation, gather sensitive information or break into computer devices. 

Malware is a general term which refers to different forms of hostile, intrusive or annoying soft-wares. It includes trojan horses, spyware, adware, root-kits, viruses and other malicious programs. Most of the malwares disguise themselves as having some benign function, and may come from reputable sites/ mails. 

Some of them track your activities, show pop-ups, redirect sites etc. They can reinstall themselves after removal or hide themselves deep with the system to make them difficult to find and clean.

It’s easy to get enticed by the offer of pop-up ads. By the time you start seeing signs of a malware attack, your system shall probably get compromised beyond repair. Spam and pop-ups laden with malwares can arrive from different sources in a variety of forms, including:

  • Attachment sent through a spam email

  • Links within the body of a message

What are Fake Pop Ups:
You must have noticed a variety of pop-ups appearing on the computer screens. They are usually generated by websites to guide user, provide useful information, offer newsletters etc. In short, they are meant to be useful – to help in filling out forms, to apply for discount code etc. However, not all pop-ups are useful and benign. For example, a pop-up installed by malwares can entices the user to click on a button that redirects to a phishing page. 

Some of the pop-ups display false security warning as part of pop-up scam e.g., Ransom-ware pop-up. An example:

You should not respond back to such illegitimate pop-ups. 

How do Pop-up Scams Work?
As shown above, fake pop-ups are generated by cyber criminals using malwares. The pop-ups flag fake security issue, virus attack, technical problem with the system or anything else which is alarming enough to make the user feel insecure and look for immediate solution. Generally, the scammer, instructs the victim to call a phone number shown in the pop-up, in order to demand payment for technical support to resolve the non-existent threat. 

Thus, cyber criminals use these pop-ups to extort money from concerned users who want to fix their problems and resolve threats that do not exist. 

How to Identify Fake Pop-ups:
Following is the procedure we suggest, to know the veracity of the pop-up in question:

  • Look for spelling mistakes and unprofessional images: Poor spelling, grammatical and punctuation errors, unprofessional looking symbols and images, fake logo etc. are sign of a illegitimate pop-up. A professional company would never commit such mistakes. 
  • Try to close your browser: Fake pop-ups may cause the browser to switch to full screen mode. So, if your browser is already at full screen mode, try to minimize or close it. If unable to do so, it’s a pop-up scam. 
  • Verify the phone number: Cross check the phone number listed in the pop-up with the official phone number of the security provider, the pop-up is claiming to be. A legitimate company phone number can be verified by a simple Google search. If the phone number search yields no result, it is most likely a scammer’s number.  

How to Remove Fake Pop-ups:
Step 1: Click on Ctrl+Alt+Del and select “Task Manager”. 
Step 2: Choose the browser in which pop-up was detected. 
Step 3: Click “’End Task” to close the selected browser.
Step 4: When you re-open the browser, ensure that you don’t restore the pages.

  • Download and install a credible Anti-Virus
  • Disconnect the internet to prevent further interaction with the pop-up 
  • Reboot the system into Safe Mode
  • Delete temporary files using “Disk Clean Up”
  • Run complete Anti-Virus scan
