I realize that MS has automated defrags for their OS in recent versions. Do us all a favor though and run defrag c: /A and post it here. Thanks!
actually, you're just proving your own ignorance on this subject.
Firstly: Fragmentation of a hard drive is not a function of the operating system. it is a function of the File system type. A fat32 system will be more fragmented than a NTFS system. Fragmentation is a by-product of the File systems way of handling free space and continuous file system usage.
with FAT32 and NTFS, fragmentation occurs because the filesystem doesn't check if it's the best place to put data, it just starts dumping it in the first available spot, then skips over used space, and continues on. It operates on the "save first, then we'll clean up later" mentality. EXT and HFS+ operate differently and first scan for the best place for that data before writing it.
there are pros and cons to either approach (HFS and EXT take slightly more time to write to do this)
Windows Provides the defrag tool as a counter to this. Microsoft however have previously attempted to switch Fielsystem types (during Vista development they were creating a new one, but public backlash stopped them)
HFS+ does also run the problem of having to use more space on disk and performs it's de fragmentation on the fly.
However, the defragmentation discussion becomes moot when factoring in SSD and flashbased storage devices

Torrents are no safer / insecure than any other file download method.
it is also non specific to what OS you are on, as trojans / worms can be found for most systems. Windows tends to get the brunt of it due to sheer volume of windows products that are out there (something like 90% of the world is on windows)
Like any system, regardless if windows, OSx or Linux, you should always be cognitive of the source of your download and ensure that you are not installing something that you cannot verify the source of.
