His main problem seems to be offensive messages and he is particularly concerned of some of the lewd requests by some of the posters and various pop ups by msn messenger.
I did a few internet searches to try to find out what action is required to remove or block msn messenger, but am now completely overwhelmed by the conflicting views and suggestions as to what is required.
So I am here to ask the experts what I should do to help him with his problem.
Details of his system are follows:
1. Windows XP fully updated which I understand includes a firewall of some sort
2. No other firewall
3. AVG Free Virus Protection
4. Various other protection including Spybot and Ad Aware
I suppose he will also need to block Yahoo Messenger and any others in common use.
Any advice to help will be appreciated.
P.S. I have no idea how to block ports as has been suggested by some. Please help.
