Question Most .rar files corrupted (NOX?)

[ElysiumField]

So i was trying to install NoxPlayer.
when it's done installing. i noticed it was bundled with Yahoo Search Manager and ByteFence. then i uninstalled them right away. the Yahoo Search Manager was a little bit tricky to uninstall. i needed adwcleaner for that.
and then i realize most of my .rar files are corrupted.
and my browser forced close sometimes.
. I'm 90% sure Nox is the cause.
Can anyone confirm this, or give solution pls.

it shouldn't corrupted other file. did you install some malware on your system?
what app do you use to open rar file? try reinstalling that?

i scanned my pc with malwarebytes. looks like YahooSearchManager leave some reg files.
the browser is fine now, no force close. i don't know if this has something to do with the corrupting rar.
.
i downloaded a new version of winrar. same thing
i tested the .rar files on another system before and when itried to extract them, same problem.
however i tried chkdsk /f last night. and it works. i think my drive is dying.
Thank you|
