I delete all eset registry.... and still the problem. I resolved by format and reinstall windows. The only way I found. I'm a computer technician and I Know what I do. I got Technician licence in 2004 and perfect 10 on class. I'm a software tester in all instalations and see how to work. ESET is the best antivirus...... But this time, the installation got bad. I'm sorry for my report but the truth is more better.
