MMORPG i was searching around but i might have signed up and forgot about it but how can i know if i am hacked coz all my emails are fine none have been read and i my computer seems fine

Hi, Wicca.

First things, first -- change your e-mail password. Then change the password for the game sites, preferably making each of them different, and most definitely different from your e-mail password.

Next, it wouldn't hurt to update your antivirus software and scan your computer.

but how can i know if i am hacked

done now how do i know if i am hacked

If you are using the same password everywhere, it is possible, as that does appear to happen at game sites. That is why I advised you to change all your passwords, making them different for each site.

Have you updated your antivirus and/or anti-malware software and run a full system scan?

the only problem is no usually proccess is running and my computer is not running slow

Hi, Wicca.

In that case, it sounds as though you had registered at that site and forgotten, as you indicated in your initial post.
