it takes forever to build the file list.

i only have about over 140 gb in this computer, but i don't know why, recently, it starts to take at least two hours or more just to build the file list. it used to take only about a few minutes, definitely less than 15 mins for sure.

i checked for spyware with malware, it didn't find anything. it seems that recently my internet speed also goes down after using it for a while.

and when i use facebook with firefox, it will show me the ireland flag to indicate the server's location.

I would start by doing a chkdsk /f on that partition and cleaning all the junk you can afterwards (temporary files, internet caches and so on).
