>> They logged into my computer from where they was. <<

Since the scammer accessed the computer, they probably did one or more of the following:
• Disabled the anti-virus software
• Added a lot of malware to the computer
• Copied the Contact List (so they can email your soon-to-be ex-friends)
• Copied any financial data or passwords they could find
• Compromised the ID
• "Zombied" the computer, so it would respond to THEIR commands sent via internet
• Deleted some important files
• Asked for money to repair the damage they caused

Now, what can you do?
1.  Pull the cables on the computer, so it cannot access the internet.
2.  Change ALL  passwords stored on the computer
3.  Run FULL malware scans on the computer, in "SAFE" mode!
4.  Change the passwords again, particularly if the malware scans showed anything
5.  Inform your bank and credit card companies
6.  Sign up for credit monitoring, and check the status frequently
7.  Possibly bring the computer to a local repair shop, and tell them the story.
8.  Tell friends what happened, so they can be aware of strange emails from you
9.  Plug in the computer only AFTER all the above have been done
10.  Change the passwords on all online accounts.  Even better - access a "safe", uninfected  computer, and chance your online account passwords RIGHT NOW.
