>>1136159>the technician pointed out that the me and his brother both used jdownloader2 a lot and both had an hd fail because of a corrupted boot sector.This kind of "X happened so Y" thinking shows they don't understand what's going on and approach the computer as a magic box you apply incantations to. Next time take it somewhere else.
It's the OS's job to not let anything write to the boot sector, and there is no OS from the past decade that doesn't do a reasonably good job of this. To write to the boot sector in Windows, you need a chain of exploits that can
- take ownership of a user's process/an internet-facing service
- drop the "restricted" UAC token
- bypass the kernel permissions on the disk drive device
There's no way you're doing that by accident, and if you're smart enough to do it on purpose, you're smart enough to not fuck up putting a virus in.
