@Wellies,
I'm glad you do understand me.
Eight years ago I had a classical security-setup like everyone, but I was still in trouble regularly, so I had to do something entirely different and I had to solve 4 major problems :
1. Uninstall Programs
Alot of people like to try new software, but not to keep them.
Installing/Uninstalling softwares creates a big mess on parition-C after awhile, because no software is able to install itself completely, how ridiculous it may sound. This is caused by sloppy programming.
So I had to find a solution that removed a tested software completely without a trace.
2. Cleaning softwares
Cleaning softwares, do usual a pretty good job, but not good enough.
So I had to find a solution to clean my partition-C thoroughly and for ALL softwares
And no cleaning softwares anymore on my computer.
3. Registry softwares.
Registry softwares remove innocent registries, too many registries, they aren't safe enough and they don't restore the original values of registries.
So I had to find a solution to clean Windows Registry safer and restore its original value.
And no registry softwares anymore on my computer.
4. AV/AS/AT/...-scanners
Scanners don't remove every malware : malware not on the blacklist and undiscovered malware.
So I had to find a solution to remove malware 100%
And no scanners anymore on my computer.
SOLUTION
I solved all these problems by replacing my dirty partition-C with a clean partition-C during each reboot, just like people replace their dirty shirt with a clean shirt. It was that simple.
I only had to find the right software to do this : FirstDefense-ISR
From then on, my dirty partition-C was cleaned and repaired automatically during each reboot.
My computer became a paradise during 5 years until now and all my big problems were solved in one hit and I had any change on my partition-C completely under control.
End of Story :)
