Marianna, I presume this is an improved version. Why don't they merely update the old version?
If I do download the beta 6, do I do it on top of the old version or do I have to uninstall?
I would wait a "bit" - I just installed it on top of the old beta and I had NO problems installing it - but I had some "strange findings" which I guess are "false positives".
You can follow the thread in the Spybot forum here:
Don't forget it is a BETA !!
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
