Since I installed SpyBot a couple of days ago as a Home user (not free) my computer runs super slow with a lot of hang-ups. Also I noticed that my previous antivirus program is still listed in my Program Files even though I've uninstalled it and it doesn't come up in my programs to uninstall. I right-clicked on the folder and clicked on SpyBot Kill Folder but nothing happened. Is this really the best program to fix my issues? If not how do I get a refund?
