if you dont mind, for our knowledge, what was the solution to the problem?
I cleaned the old system restore points , that saved me about 1Gb or more , plus the windirstat , helped me see what really was occupying my disc space
then i realized about some things that were not viruses but things i installed in the past , bot still when i check my disk space time after time it keeps lowering
but after some seconds it turns back how it was , i really don't know why is that happening , but i don't care as long as it turns back how it was .
So by my opinion that was the thing that solved it , i mean i don't have to think anymore i have a virus on my pc or something .
Maybe i wrote a long text but i just wanted to be more detailed , hope you understood . Thanks for the help again
