Hi, I'm taking care of my little cousin's comp once a year at the hollidays when the family get together and last year I had installed ESET Smart security, password protected, set it to automatically block corrupted files etc... etc... When I went there tonight, noticed the liscence was expired since 22 days and something might have entered the machine as Windows gives a message that the key can't be validated and upon installing the new ESET liscence it as a very hard time scanning. It doesn't proceed. Anyone might have an idea of how to take care of this? The XP key is a multi-user one and I have it on my machine at home and at work and everything works fine. Forward thanks! PS: I noticed the pnkbstra.exe process that seems fishy.
