Cesar: Sounds like you need a specific tool for this job its called hijack this and can be found here.

*Important* : Hijack This! needs to be installed in its own folder, as it creates backups that you may need later (create a folder in "My Documents", for example...). This tool can be dangerous when handled improperly, so, PLEASE DON'T FIX ANYTHING WITH IT YET !! and wait for instructions. Run Hijack This!, then click on "Scan". Once done, the "Scan" button will change into "Save log". Save the log, then copy/paste it here so we can have a look.
