What to do when you have a virus

If you experience blue screens, your computer running slower than it should, random reboots, errors, or excessive window pop-ups then most likely you have a virus or spyware.

What you should do

  1. If you suspect your computer is infected, stop what you are doing and close all the programs and files that are open.
  2. Immediately run your antivirus software. If there are updates for your computer or even the antivirus software, don’t, run the scan first before performing any updates.
  3. After running the scan, then install any updates then run it again.
  4. If your computer is still acting up, check for spyware.

Avoid deleting programs and files as this could cause more harm to your computer. If you haven’t backed up your computer, it’s a good time to back it up. If, by chance, your date is infected with a virus most likely you will be able to recover it. That way you won’t lose any important files.

What if the virus won’t let you access your antivirus software?

If a virus is on your computer, you may get an error when you try to open the antivirus software. Below you will find three ways to handle the situation.

  1. Use a rescues disk. Many antivirus programs will require you to make a rescue disk during the instillation process. If you did make one, put it into your computer and reboot. The purpose of the rescue disk is to load before windows and any other program in order to locate the virus.
  2. Another option is to use online antivirus software. Many companies offer free online software that you can use to scan your computer. The companies you can get free tools from are:
    1. Avast Virus Cleaner
    2. Panda Activescan
    3. Trend Housecall
    4. Kapersky online virus scanner
    5. If you have a network set up, use it to access your files from another computer and use that system to scan the computer and drives. If you don’t have a network, then remove your disk drives carefully and install them on another computer.

If you tried all of these suggestions and your computer is still acting up then it’s time to seek out a professional. Maybe you have a friend or family member who is a computer whiz but if you don’t, there are many companies out there who will fix up your computer and make is new again. You can find local computer repair companies in the phone book under “Computer repair and services.” When finding the right company for your computer problems, make sure you get price quotes. Sometimes places will let you bring your computer in for a free estimate.
