Are the hidden files in C: neccesary?

[tombance]

Ive just had to delete a hidden virus from my computer and in the process came across a lot of hidden windows files in my C: directory:

Recycled
WUTemp
Bootlog.prv
Bootlog
Config.sys
Detlog
lo.sys
MSDos.---
MSdos.sys
Setuplog
Suhdlog.dat
System.1st

I was wondering whether these files are really necessary, or could I just delete them and if so would it speed up my computer?

Do not delete does files, they are really important for your pc to work.(this is why they are hidden).

For example Recycled is your recycle bin. Config.sys is one of the three most important files on your hard drive it permits booting up your pc(with command.com and autoexec.bat). Io.sys permits i/o(input and output).

If you want your PC to work, do not delete these files.

In ancient times they had no statistics so they had to fall back on lies

The last guy was right, they hide them so you won't delete them. But bootlog.prv is an older version of bootlog, you can delete it. Same with MSDos.---

Config.sys is one of the three most important files on your hard drive

I must beg to differ.

Command.com
IO.sys
MSDOS.sys

are the 3 most important. Autoexec.bat and Config.sys, although important in some environments, are superceded by Windows.
