Files keep getting random corrupt

[Freihei]

I use sfc /scannow, chkdsk /f /r, switch browser when download, use bittorrent instead download individuals rar files, switch source files im download from, different server from different people ( still the same file i need ). AND IM STILL RECEIVING THIS GOD DAMN ERROR
Im also try to ignore the error and continue extract, and it seem it corrupt at everything, 1a.bat 1b.bat 2a.bat 2b.bat etc etc is corrupt
I really need help guys, for now im can only download small file, only big file is affected

Torrent has hash check feature ... get a good client like qBitTorrent and right click on a torrent when it's done and select Force recheck - qBitTorrent will scan the downloaded file and make sure the download was correct.

 

Update your programs... if you use WinRAR get a newer version. I'd recommend just using the open source 7zip as it can unpack all major archive formats just fine.
