At every sign-on, Norton History records "Intrusion Prevention has been enabled", then "Intrusion Preventioning monitoring 1989 signatures"...then IP version Engine Version 4.9.06 ....
This began after a friend sent me an infected file, which Norton thankfully would not open, but afterward some friends got the same infected file with my email address on it as sender.
Now I'm wondering why my computer seems to be attacked upon reboot--
Is my computer infected? No scan catches it if it is, yet the IP still kicks in upon every reboot.
How do I stop the attempted "intrusions" which I never had before I clicked on the infected file?
Thanks so much.
