Hi Gayla :
After running the Norton Removal Tool, it would be wise
to use your computer's "Find" feature, selecting "All files
and folders" and using the term "Symantec" and later
"Norton" and "Delete" all appropiate Items. This would be
an additional "step" to ensure that Norton is OFF your
computer, so that any remnants would NOT "conflict"
with the newly installed Avast .
Did you realize that Microsoft will issue no more Updates
for your Operating System !? As time goes by, it will
become increasing vulnerable to all the bad "stuff"
coming through the phone lines; perhaps time for a
"New" Operating System !?
