Hello,
I'm facing this problem since a long time and unable to resolve it.When I double click on my drive volumes(C:\,E:\....) in My computer Window it doesn't open instead shows some error i.e Access is Denied but when I right click on the volume (C:\,E:\...) and select open then I'm able to open the volume. Please help me I'm totally irritated by this problem.

You need to set permissions on those volumes. Also, you need higher level account (administrator level is the highest).

To check whether your account is administrator one, open the control panel (classic view) and open "User Accounts". In the lower left corner should be your account name and account type (should read "computer administrator")

To set permissions follow these steps:
Open control panel (classic view)/folder options. Scroll down advanced settings window and uncheck the "use simple file sharing".
Apply and rightclick on the volumes in question, select properties and click on "security" tab. There you'll see detailed sharing permissions/restrictions for all relevant accounts on that particular drive/file/folder. (Taking that you have administrative permissions) click on "Administrators ([computer name]\Administrators)" (first one from the top) and check allow on "full control" and click "apply".
If you see your account name on the list, either remove it or allow full control. If you are only user on that PC I suggest removing it from the list, for you are administrator and comply with "administrators" permissions.
After setting the permission, click on the "advanced" button. In the first tab select "Administrators ([computer name]\Administrators)" (same as before) and check the "Replace permissions entries on all child objects with entries shown here that apply to child objects" and apply.

Repeat those steps on all volumes in question.

I'm sorry but I'm using Windows XP home edition and I didn't find any such option like advance setting in my folder option window neither did i find any such security tab on right clicking the drive and selecting properties.Please help I'm still facing the same problem.

hello

plz post hijackthis log
also tell me wt all thing u get in the list when you right ckick the drives, n in bold fonts.
(eg: open, explore, search, copy,.. properties)

try this
-------
open my comp>goto tools>folder options
select "show hidden files"
uncheck "show system files"

goto each drive by rightclick>explore only. DONOT double click drives.

delete the file with the name "autorun.inf"

restart comp OR endtask n run explorer.exe thru taskmanager

this will solve the problem....


precaution
-----------
these setting are done by many viruses which spreads thru removable media.
never double click removable drives
always right click n do explore/open

ok let me try it and i will let u know in few minutes

No such autorun.inf file found and u told me to list the items shown on right clicking the drive. They all r ok as they should be but only one item i.e open option is twice,once as open(0) which on selection gives the error and other as open which gives me access to the drive.

check if u have done
"show hidden files"...
check if you can see system files in c: drive

No man , actually this problem started since my antivirus detected ctfmon.exe being corrupted by a virus ctfmon.vir

ya, this is probably ctfmon.ex e virus

check this:
C:\Documents and Settings\<username>\Start Menu\Programs\Startup
do u see ctfmon.e xe

or do a search for this file
do not delete the file in the windows folder

to see hidden file
-----------------
do u know making changes in registries to show hidden files... then do it

No its not there in C:\Documents and Settings\Owner\Start Menu\Programs\Startup.But ya i can find it in my system32 folder wht should i do ?
