Guy....don't fuck around with AVG, malwarebytes, etc. They are good programs but, honestly, do you
really trust that they will clean everything and get this key logger? When was the last time you when online to your bank or ordered something over the internet? Do you trust that these will clean your computer so you can safely go to those websites and type in your account or cc numbers?
Backup any important files/data and wipe the computer with something such as
killdisk, then reinstall, Windows with all applications and drivers, then make sure windows and all applications are up to date. It looks like you are using Windows 7 so I would suggest to you, after all this, to make a backup image of the drive which will make future problems easier as you will only have to wipe and copy the image back.
Some may disagree with me and say this is overkill, but if this happened to me, that is what I would do. Also, download Microsoft Security Essentials, or pay for a AV subscription. No AV program will get everything, but pick one of the better/best solutions, keep the definitions up to date, and setup a weekly full scan of your computer.
One last thing, stay away from dubious website, especially porn of downloading software, music, movies, etc form untrusted websites.
If you want to do when I recommended but not sure how to proceed, I will be more then willing to help out.
ETA: Also, don't install more than 1 AV program as they tend to fight each other and cause problems, usually thinking the other is a virus. Symantec with Malwarebytes is fine, but AVG and Symantec would not work well.
Absolutely correct. I cringe every time I see someone saying to run malwarebytes. The only complete solution to an infection is a wipe & reload.
