Windows XP consumer security software providers

10:56:00 AM | ,

Some companies use products that appear to be antivirus programs to install viruses or malware on your computer. When you install the program, you might also be installing the virus or other malware, without knowing it. Many companies, including those listed on this page, distribute antivirus programs. You should carefully investigate the source of antivirus and other products before downloading and installing them.
The companies listed below provide consumer security software that is compatible with Windows. Just click the company name to see the Windows-compatible product they offer. For business security software that is compatible with Windows XP, please contact your security vendor of choice.
Important: Before you install antivirus software, check to make sure you don't already have an antivirus product on your computer. If you do, be sure to remove the product you don't want before you install the new one. It can cause problems on your computer to have two different antivirus products installed at the same time.
