How to Remove a Virus That Slows Down the Computer

A computer virus is a small program that infects your computer and interferes with the proper functioning of your computer system. One of the most obvious symptoms of a computer virus is a slow computer. Additionally, computers that are infected with viruses may freeze or even crash. Computer viruses have the ability to spread over time. Thus, if you do not remove a computer virus, your computer can actually become slower. Fortunately, if you are using a PC, there are several tools available to help you remove a computer virus from your computer.

Computer viruses can slow your computer to a crawl.

Run Your Antivirus Program

Step 1

Open your antivirus program. If you do not have an antivirus program, consider purchasing an antivirus program or downloading a free antivirus program, such as AVG or Bit Defender.

Step 2

Update your antivirus program. Having an up-to-date antivirus program is necessary to detect and delete the newest computer viruses. If you do not know how to update your antivirus program, consult the manufacturer's homepage.

Step 3

Run a full scan of your computer using your antivirus program. Most antivirus programs give you the option of running a full scan or a quick scan. A full scan may take several hours, but it will scan your entire computer for viruses as opposed to just the areas where viruses are most commonly found.

Step 4

Restart your computer.

Tip

Not all antivirus programs are created equal. Consider running more than one antivirus program in order to increase your chances of detecting and deleting all the computer viruses on your computer.
