I have found a folder called Tracing in the register, it's inside software, microsoft.
I was woundering if it's something that should be there or if can delet it.

Hello Roman,
Nobody can tell you if you can delete a folder called "Tracing" unless that you are using it in your computer with a specific program... what did you find inside ?
Do you have a anti-virus to check for your system and files ? Do you run a firewall to protect you from internet and stealth you from any Hickjacking experience ?
Best would be to start by the begining, run a anti-virus program in your computer to detect if anything is wrong....
Norton is a very effecient program to be used at home, you need to buy a copy of the program to receive permanents updates...
