I am sorry your experience was bad. Unlike many apps that will takeover your whole PC, Process Lasso makes no system setting modifications, does not inject inself into other processes, or make many changes at all. The things it does do are logged, and of a temporary nature. Uninstalling it removes everything. Of course, as with all software, do beware of pirated copies on the 'scene', as who knows what extra payload some of them may carry. The same goes for many rogue download sites. Be SURE to get our software from our web site. Also note that our installer is a SINGLE EXE in a ZIP file and is digitally signed by a certificate in our name. Using this information can help you ensure you got a real and unaltered copy, wherever it was retrieved from.
