It's easy to install, very effective in stopping key loggers from logging your information or accessing sensitive data without you knowing it has been done so I would say its one of best anti KeYLOGGER softwares out there right now! Nothing really because everything is good about this software but maybe if they have an option for more than 1 device at once like having 2 USB devices connected simultaneously with only different IP addresses attached that could be better? We are using spy shelter as our firewall/antivirus solution against malware threats which we sometimes get through internet browsing etc (especially when visiting adult websites).
