Remove NIS to load Avast

I have my sister’s vista 32 machine and as her Norton Internet Security has run out I want to remove it and put Avast on this desktop pc.

Guess I should have written first but I ran the Norton removal tool already. It succeeded but I know there are many tentacles of NIS.
What do you recommend that I do next.

Will it be possible for Avast to work on a machine that has had Norton for 3+ years?
Thanks in advance for any help.

Yes it should work fine. After you have been running the NIS removal tool “all” left-overs of the program should be gone from your computer except some in the /system32 drive. I belive its their lexicon’s or something that is left over after you’ve been running the NIS removal tool. You can always come back to the forum if it didnt work!

You will find the uninstall tool and instructions here http://singularlabs.com/uninstallers/security-software/
Just be sure you select the right one. :slight_smile:
