Don't ever go online without a firewall and don't let him through it.
Well, since you have to add him again, do the best you can to protect yourself.
Make sure that you have installed anti-virus software. Then change your IP.
I had the same problem a long time ago, outside of not adding them period & making sure you use a firewall, Do not accept any files he might send you.. There are lots of ways to crack into one's pc via 1 on 1 file sharing. What happened to me was my "cyber stalker" sent me a rather large music file, at this time I had no firewall.
Once someone hacks through your messenger, they can then acquire your ip address. Once they have that, they can use any of the remote admin. tools to preform netbios hacking. Thankfully I found the little skagg lurking on my laptop the next day when i did my daily scans. Needless to say him and I don't speak anymore, and I now don a firewall.. ..lol
what do you mean you have to add him again ?
I find pipe bombs to be effective.
The easiest way is not to add him - period. Don't let someone you can't trust into your network. You couldn't trust him then - what's changed? The best predictor of future behaviour is past behaviour.
And take a course or two in computer security. Some of the best geeks are girls! It'll do a lot for your confidence too.
Just pull their power away bit by bit....mine doesn't know which end is up anymore...90% of the calls are fake, she cannot see or hear 250 calls in the last 3 months, she cannot see a bar, club or outing in the evening....all she can say is she saw me at CVS....we know what were doing.....she's powerless....we have a staff still in charge of CNN.

My hacker are scorned women. They do basically nothing all day then they tell me i ate cornflakes. Many husbands are hacked into by their own wives. Do you know how many lawsuits we have now. My cousin have never hacked into their husbands emails, texts, nothing. No reason too if there is trust...i assume its a trust thing. The day i have too hack into my boyfriends texts too tap into what he is doing....i better get my self esteem check.
