If you use more than one antivirus or antispyware program at the same time, your computer may experience decreased performance, become unstable, or restart unexpectedly. Before you install FEP, or to resolve many issues with FEP, including installation issues, you must first completely remove any Internet security programs from your computer as described in this topic.
When you remove your currently installed Internet security programs, your computer is in an unprotected state. If you have problems installing FEP after you remove your existing Internet security programs, contact FEP Support by submitting a case online.
You will need to restart your computer while following these instructions. Write them down, print them, or bookmark this page (mark it as a Favorite) to make it easier to find this topic again.
