Some time ago I installed Returnil and all seemd OK when I used it. I forgot about it for some time and then yesterday when I launched Returnil and tried to enable it, my pC went to a crawl and nothing happened and I was not able to run any application, e.g. Firefox, Google Chrome. Returnil was using approx. 99% of the CPU. I decided to uninstall and then re-install returnil but this didn't help. Both times when I tried to kill the Returnil process in Task Manager, nothing happened. I could not kill the process and I had to reboot to gain normal PC behavior. My system generally runs well and I have no problems with any other applications. I have XP Home with SP 3 38.2 GB drive (12.2 free) 735 RAM Thank you for your time. Any help will be great appreciated.
