Tutorial To Remove Computer Virus
What is a Computer Virus?
A computer virus is a malicious program that self-replicates by copying itself to another program. In other words, the computer virus spreads by itself into other executable code or documents. The purpose of creating a computer virus is to infect vulnerable systems, gain admin control and steal user sensitive data. Hackers design computer viruses with malicious intent and prey on online users by tricking them.
executable file
One of the ideal methods by which viruses spread is through emails – opening the attachment in the email, visiting an infected website, clicking on an executable file, or viewing an infected advertisement can cause the virus to spread to your system. Besides that, infections also spread while connecting with already infected removable storage devices, such as USB drives.
5 Computer Virus
1.Browser Hijacker
Imagine typing in an internet address and automatically bouncing through several different sites. When this happens, a browser hijacker is responsible for the incident. Unfortunately, hijackers are usually attached to appealing toolbar's, programs and other free downloads you choose. They often have the word "search" in their names. A good security program can detect nearly all of these.

2.File InfectorOne of the most common types of computer viruses is a file infector. These viruses attach to host files, so this means they usually stick to files you use often. Any time you open or run the file, the virus is running. It can even take over the file completely.
3.Macro VirusThis is another type of file-based virus. It attaches to files made from programs that support macros. Some examples are Microsoft Excel and Word, and people often unknowingly download them from email attachments. A good security program scans these types of files before you download them to detect any threats.
4.Polymorphic Virus
These viruses are harder to detect. This is because security programs scan coding to identify viruses, but these specific viruses both encrypt and change their coding. They continually changing their operations over time, which may affect the programs you use.

5. Multipartite Virus
Some types of computer viruses only spread in one way, but these ones spread in several ways. Their actions usually depend on the form of operating system you use, certain programs on your computer or your use of specific files. It can have multiple actions, so it is one of the most frustrating viruses to deal with.

How To Remove Computer Virus?
- Step 1: Enter Safe Mode
Do this by turning your computer off and on again. Then, as soon as you see anything on the screen, press the F8 button repeatedly. This brings up the Advanced Boot Options menu. From there, choose Safe Mode with Networking and press Enter. For now, keep your PC disconnected from the Internet.
- Step 2: Delete Temporary Files

While you're in Safe Mode, you should delete your Temporary Files using the Disk Cleanup tool:
- Go to the Start menu
- All Programs (or just Programs)
- Accessories
- System Tools
- Disk Cleanup
- Scroll through the Files To Delete list, and choose Temporary Files
Deleting these files might speed up the virus scanning you’re about to do and could even get rid of a virus if it was programmed to start when your computer boots up.
- Step 3: Download a Virus Scanner
There are two types of scanners that can detect and delete computer viruses and malware: real-time and on-demand:
- A real-time scanner, like AVG AntiVirus FREE, scans for viruses in the background while you’re using your computer.
- An on-demand operating system scanner, like Microsoft Safety Scanner, needs to be run manually each time you want to scan.
Using both types of scanner might be necessary to remove the virus. So if you don’t have a virus scanner installed, this is the time to reconnect to the internet and download it.
Even if you can’t connect to the internet you might still be able to download Microsoft Safety Scanner because you started up your computer in Safe Mode with Networking.
- Step 4: Run a Virus Scan
Run the on-demand scanner first, then your real-time scanner. One of them should be able to identify the virus and remove it. But running both scanners increases your odds of success.
If need be, remove a virus manually
Some viruses must be removed manually. You should only attempt this if you are experienced at using the Windows Registry and know how to view and delete system and program files. If you’re not sure, contact an IT expert who specializes in removing viruses.
