Been using Spywareguard for quite some time now and haven't noticed any problems with the program until recently. Would turn off PC, get to the windows screen telling me windows is shutting down, and then would hang for about 4-5 minutes before finally shutting down. Through the process of elimination, Spywareguard was the culprit. If I have it running and then manually stop spywareguard by way of Task Manager, before shutting down, my PC still hangs. If I don't initially start and use the program at all, shutdown only takes several seconds. Went ahead and downloaded 2.2, same problem. Apparently, Spywareguard is still using the registry during shutdown, even if I manually stop the program. Could be some kind of conflict with other programs I run, NOD32, Ewido (paid version), Kerio4 firewall (paid version), spywareblaster, teatimer. Would like to know if anyone else has had this problem with SG. Guess I have enough protection without using SG.
