The thought came across to me today about internet security and I remembered a point in my history where my account for World of Warcraft was compromised. Let me give you the short version of it.
One day I received an email from Blizzard Entertainment telling me my account was banned for suspicion of illegal use. I immediately fired up WoW to check and see if this was another of those imposter emails. It was not. My account was in fact banned. Panicked, I immediately found Blizzard's customer support telephone number and phoned. I began losing my temper on the poor sap who answered the phone because I knew that I was not doing anything against their terms of service. The email stated I was using my account for gold farming. I laughed at him and said I was lucky if I had 1000 gold. He asked me to log into the WoW Armory, look up my character, and tell him what I was wearing for gear. I did so. My character was naked. He informed me that my account was compromised and that someone took all my stuff and used my account for illegal gold farming. Shocked I asked how could this have been done? He instructed my to download and install Malwarebytes and to run a scan. He said he would wait on the phone for the results of the scan. Once the scan was done I was shocked to find out there was a key logger installed on my PC. We used Malwarebytes to remove it. He said they would release my account back to me but first we needed to change the password and then it could take up to 48 hours before I could play my character again. He also instructed me to get and attach an authenticator to my account so that in the future this could never happen again, even if they got my password.
Now I run these programs on my PC to keep it running smooth and virus free:
I worked at a computer store for about a year and I found the trouble with running any other virus programs was the PC would get bogged down no matter how much of a super computer it was. Programs like Norton, AVG, Avast and so on were not necessary when Windows comes with basic built in protection. Programs like Superantispyware removes things like tracking cookies and some other adware/spyware type software and files that simply browsing a website can install. Malwarebytes removes naughty stuff like key loggers or trojans. CCcleaner removes other tracking cookies, cleans out temporary internet files that get stored on your PC from every site you browse as well as repairs windows registry errors that happen from everyday computer use. I can assure you that using these programs together will keep your PC running smooth and bug free. I have even simply run CCleaner alone to speed up friends computers with success.
Most if not all of us nowadays have a smart phone. If you haven't already you need to get the Blizzard Authenticator app and attach it to your WoW account. With the authenticator attached to your account, everytime you log into WoW on your PC, especially from a new device, it will ask your permission on your phone VIA a popup notification, or it will ask you for the code that appears on your phone screen. You can set to remember and trust your device so that you do not have to perform this every time though. This eliminates anyone ever getting into your WoW account.
