Internet Explorer (IEXPLORE.EXE) is trying to connect to www.symantec.com
using remote port 80 (HTTP - World Wide Web). Do you want to allow this
program to access the network?
This message appears because the application has been opened, either directly or indirectly by you, or
by another application.
If you didn’t open any program or click any link and an application tries to access your network
connection, there may be a number of different reasons. However, if you cannot see any reason that
application should try to access your network connection, it is always safest to click No. This message
might indicate the presence of a Trojan horse on your endpoint, something that needs to be checked
immediately.
Changed application messages
Occasionally, you might see a message that indicates an application has changed.
●
Telnet Program has changed since the last time you opened it, this could
