As I have posted before, any time I wanted to use Privazer with BitDefender installed, my computer used to crash.
I was contacted by the BitDefender AV developers about that issue. (Thank you very much.)
I've followed their advice and re-installed/refreshed Windows 8. After going through numerous Windows updates, I installed BitDefender Windows 8 Security, followed by Privazer installation.
I ran Privazer without any Problems.
I've installed CCleaner, WiseDisk Cleaner. Again, I ran Privazer without any problems.
I would like to say that my problems related to Privazer and BD AV are over, but...
After one day of re-installing Windows 8, BitDefender, Privazer, CCleaner, WiseDisk Cleaner, Auslogics Registry Cleaner, my Windows 8 computer really crashed, this time for good. Just in case, I installed and used Auslogics Registry Cleaner last before I turned off my computer. Please be careful about it. Also, I had Ashampoo Winoptimizer installed earlier. In my opinion, be careful about ALL THOSE OPTIMIZERS.
Please note, that I DON'T BLAME BITDEFENDER ANTIVIRUS FOR IT.
I truly believe that Microsoft Windows 8 OS is to blame for all those nasty issues.
To my regret, this time, I could not refresh, reset my Windows 8 or even run MS-DOS.
I needed to use USB Flash Drive to install Windows 8. I tried but could not repair Windows 8; therefore, only by reformating the drive and wiping out all my files, I was able to install clean Windows 8 OS.
How could it happen? What was the reason for not being able to REFRESH Windows 8 OS? Why did I get the message that my "hard drive is locked and could not be repaired"?
What was that message that I could not install Windows 8 to GPT disk, when I had Windows 8 installed on the same disk?
Many questions, but I think they belong to a different forum, like "Why you should not use Windows 8".
Again, I went through Windows 8 updates and re-installed BitDefender.
It's a new beginning.
