How to Fix the Virus From Yahoo Messengerby Greg Lindberg
You can be susceptible to viruses when you are searching through websites or downloading programs on the Internet if you are not protected from virus or have low security. When connecting to Yahoo! Messenger you can obtain the Trojan virus, which will quickly infect your computer. This virus is preventable if you have software installed on your computer that will help to protect your computer from viruses. If your computer does become infected with this virus while you are on Yahoo! Messenger the virus can be sent out to people who are on your friend's list. You must get rid of your Yahoo! Messenger immediately so that you don't spread the virus.
Close out of your Internet browser and disconnect your Internet cable from your computer. This is to make sure that the virus is not spread while connected online.
Go to the "Start" option on your computer and then click on the "C drive" option. Click on the "Program Files" option and then click on the "Yahoo! Messenger" option.
Click on the "Uninstall" icon and go through the process of uninstalling Yahoo! Messenger from your computer. After the uninstall process is complete make sure to delete any Yahoo! Messenger icons and shortcuts from your computer.
Download the free trial of Norton AntiVirus 2010 from Download.com (see Resources). Save the software to your desktop and then install it once the download is complete.
Open the Norton AntiVirus 2010 software and click on the "Scan" button. The virus will be found and then can choose to remove it and any other viruses that are found on your compute. You can purchase Norton AntiVirus software at a later time as well after the 30 day trial expires in order to continue to keep your computer and Yahoo! Messenger safer from viruses.
Restart your computer and then connect back to the Internet. Go to the Yahoo! Messenger website to download the application again. When you sign in with your Yahoo! account your information and friend list will remain the same, but the virus will be gone.
