My computer has been acting funny.I am not able to get to yahoo or google it takes me to some other bullshit search engine.Also I came home the other day and my computer was locked up and it had a message like from windows xp saying I needed the password to unlock it,but naturally I forgot it.So then I shut it down and then it was o.k.Then a day later I come home and the message on my firewall tells me it intercepted a syn attack,click here to trace attacker.Well it just kept pinging a bunch of different computers,I hope I am saying this right so someone can understand.Well I don't know too much about computers and I looked in my mcafee book for my firewall and it said that a syn attack is a kind of dos attack.Just want to know how to get rid of this shit.I would like to be able to get to yahoo or google.Any help is appreciated.
