Usually it is possible to completely remove the virus, but in some cases, it becomes difficult to get rid of the virus completely. Some viruses can block your access to security websites and also disable the system’s built in defense mechanisms, so removing such viruses and spywares is a complicated task. It is better to get technical support instead of experimenting yourself.

How to get rid of a computer virus and how to deal with viruses 
Immediate actions are needed and follow these safety tips:

• Never click on free pop-ups. Even if they offer software like anti-virus and anti-spyware, do not click on them.
• Contact any sort of IT support which you may have, like friends or family.
• If you have asked for an IT specialist, do not use your computer till he/she arrives to check the system.
• If you are not using the internet, disconnect the connection.
• Take a backup of your important data (see How to Make regular backups).
• If you already have anti-virus software installed, download the latest signature and run a complete scan.
• Once the system scan is complete, you will be advised that which applications need to be deleted from your system. Delete them!

In case you do not have an anti-virus installed, or your software is not updated, you always have an option to run a free scan from the internet. Almost all the leading security software firms provide a free online scan and inform you if your system is infected or not. McAfee and Symantec are two of the best security systems and both have a free online system scan on their official websites. They also guide you regarding the removal of viruses and tell you that which removal tools will be helpful for you in removing the viruses from your system. Immediate action is recommended because viruses can have access to your private information, like passwords and credit card numbers, and that information can be used in criminal activities as well.

A few important tips:

Computer viruses are frequently spread by attachments in email messages or by instant messaging messages. Therefore, you must never open an email attachment unless you know who sent the message or you are expecting the email attachment. Viruses can be disguised as attachments of funny images, greeting cards, or audio and video files. Computer viruses also spread through downloads on the Internet. They can be hidden in pirated software or in other files or programs that you might download.

What is a computer virus?

A computer virus is a small software program that spreads from one computer to another and interferes with computer operation. A computer virus might corrupt or delete data on a computer, use an email program to spread the virus to other computers, or even delete everything on the hard disk.

When a computer is infected by a virus or spyware, it may display the following symptoms:

1. Computer starts slowing down
2. Computer crashes, freezes or stops responding
3. Undesirable and constant pop-ups
4. Web pages take a long time to load or stop responding
5. Websites are redirected to other websites when you try to access them

How to tell if your computer is infected with spyware

Spyware is a type of software that is installed on your computer to watch and record your activity. Some types of spyware record your keystrokes and information that you type into websites or other programs and then use that information for targeted advertising or identity theft. These programs can be installed on your computer in many ways but often they are hidden inside of software such as free games, screen savers, or animated cursors.

Here are some signs that your computer might be infected with spyware:

• You notice new toolbars, links, or favorites that you did not intentionally add to your web browser.
• Your home page, mouse pointer, or search program changes unexpectedly.
• You type the address of a specific website into your web browser, but you are taken to a completely unrelated website.
• You see pop-up ads, even if your computer is not connected to the Internet.
• Your computer suddenly starts running more slowly that it usually does. Not all computer performance problems are caused by spyware, of course, but spyware can cause a noticeable change in processing speed.

Sometimes your computer will show no symptoms, even if a spyware program is running. To help protect your privacy and your computer, we recommend that you run Windows Defender or another antispyware program at all times.

Please note your computer may display symptoms which may not be related to a virus or spyware problems, as other hardware issues can also display various problems. However, if you suspect an infection, it is better to diagnose it than ignore it.
