Windows Virus – What Types Currently Exist?

In this segment of the removal article, we will explain to you all types of viruses that currently exist for Windows operating systems, what harm they do and how they enter your computer.

Tech Support Scam Windows Virus

We have seen many tech support scams out there, like Your Windows OS is Damaged, Microsoft Has Detected a Malicious Virus, 1-855-910-5732 Scam, Microsoft System Security Alert.

The Tech Support scams are the most common form of scams that may appear on your Windows browser. The scam pages themselves are not a Windows virus, but they may be caused either by an adware, a browser hijacker or even a Trojan.Clicker type of threat. Their main idea is to remain persistent on your computer and cause browser redirects to unwanted tech support scam sites. The main objective of those Tech Support scam sites is to trick you that your computer has a Windows Virus, by locking your browser with a web page, that contains a scareware message, like the example below shows:

These types of tech support scam sites are often combined with voice and animations to further scare users into doing one of the latter things:

  • Calling a fake tech support employee.
  • Downloading a rogue program.

In both cases, you may be asked to pay a lot of money to remove a virus that may not even exist on your computer. If you call a tech support number, then you will immediately be transferred to a fake employee, who wants you to get a full package in order for them to get in your computer to fix your system for errors or malware. The outcome is that you may end up paying hundreds of dollars and your Windows machine may not even have a virus.

Phishing Windows Virus

We have seen an extremely high number of phishing scams out there, among which the most popular were Google Docs Phishing Scam, Amazon Phishing Scams, “Won (1) Google Gift!”, DHL Phishing Scams, PayPal Phishing Scams and BestBuy and Wallmart scams.

Phishing is a very big problem in the world at the moment and the most often targeted areas of information are:

  • Your credit card information.
  • Your name and address.
  • Your personal information.
  • Social security numbers.
  • Other financial data.
  • Usernames and Passwords.

What the providers of phishing sites to is they may either compromise a web page or slither malware on your computer, both of which aim to cause a browser redirect, whose main goal is to lead you to a hoax website – a fake version of a real site. One good example is fake Nike site below, which is a fake retailer page, that likely wants you to enter your financial data:

When you do, those sites may not be HTTPS encrypted and may relay the information to the hacker directly via cookies. This is how many Instagram, Gmail and Facebook users, including celebrities have gotten their accounts hacked. As a result of a Windows Virus, hackers used to slither fake login pages of a social media site and then the victims typed their usernames and passwords only to have their accounts stolen.

Ransomware Windows Virus

We have seen tons of ransomware viruses for Windows out there, the most popular over the years of which were Locky Ransomware, Dharma Ransomware, GandCrab Ransomware, Cerber Ransomware, CryptoWall and of course, the legendary WannaCry and CryptoLocker ransomware infections.

The main goal of a ransomware virus is to attack your documents, videos, images, audio files, archives and basically any often used file and make it no longer openable. The main idea of this is for you to pay ransom “fee” to the hackers who hacked your computer with the ransomware virus. This “fee” is usually in cryptocurrencies, like BitCoin, Monero, Dash and others and it could range from hundreds to thousands of dollars. It is not advisable to pay ransom, because paying does not guarantee to get your files back.

Rogue Software Windows Virus

There are countless fake and rogue programs over the years, for example Disk Speedup 3.0, Win Tonic, Win Speedup, Win PC Repair, PC SpeedLane and many others.

A hoax antivirus is not exactly a Windows Virus, but it could be considered to be very harmful in a way. The main idea of those programs is to run a lot of fake scans of your computer only to pretend to detect various different types of viruses, errors in Windows or something that is harmful. The end goal is that you have go buy the full license of those programs in order for them to be able to actually fix something, so most such programs that do not give a free trial or 1 free file removal are not to be trusted by any means. This is because they are scam software that is only after your money.

Hijacker Windows Virus

Hijackers are an interesting piece of software, because they aim to take over your browser. We are seeing countless of new hijackers every day, for example V9 Hijacker, Yahoo Redirect, Get Coupons for Free, Bing Redirect, Google Redirect and many other.


The main goal of a redirect “virus” as they call it or a browser hijacker is to slither on your computer as a seemingly legitimate browser extension or a program. Then, it changes your home page, plus it performs tons of other changes to your browser’s settings. This results in an enormous amount of advertisements being shown and your search engine being changed. This is very alarming, because it not only slows down your computer, but can also redirect you to tons of malicious sites, that can infect your computer with various Winows Virus infections.

Adware Windows Virus

Adware Windows Virus infections are not exactly a virus, but they are the most widespread type of unwanted software on your computer. They can also bring a lot of viruses in it too. We have seen a lot of adware over the years, such as DNS Unlocker, Pokki, IDP.ALEXA.51, Unstopp Me and many others.

Adware often masks itself in the face of seemingly legitimate helper programs, like apps that can help you bypass geo-restricted sites, torrent apps or any other app type for that matter. They often land on your computer as a reslult of being bundled in the installers of other software as well, where the app is often advertised as a “free extra” or “optional offer”. It is advisable to remove those apps, because the ads they show may eventually lead to viruses, phishing or scam sites.

Trojan Windows Virus

Trojans are a very dangerous Windows virus infections. We have seen a lot Trojans over time, and they are often different types, like Floxif, BuhTrap Backdoor, BokBot and many others. The main goal of those Trojans is to slither on your computer undetected and perform a range of malicious activities, including:

  • Downloading other Windows Virus infections.
  • Stealing files.
  • Stealing passwords.
  • Logging keystrokes.
  • Stealing banking credentials (Banking Trojans).
  • Mining for cryptocurrencies (Miner Trojans).

They often arrive either via e-mails or via fake cracks, patches and other fake files.

How to Remove any Windows Virus from Your Computer

Removing Windows virus infections is not something that is easy. A Windows virus can keep multiple files and objects on your computer, making removal complicated. If you know where those files and objects are, you can use the removal instructions underneath. They have been designed to help you isolate the virus and remove it step by step. For maximum effectiveness however, we strongly suggest that you save yourself some time and download and advanced Windows virus removal software.
