Easiest is to reset to a recovery point from before the infection. If it really was a virus, these are probably not your only troubles.

Thanks alot for the tip jd2066.

Following the tip from jd2066 I did the following(Asuming "My Folder" is the hidden folder & "Their Folder" is the sub folder,which is also hidden with every file/folder in it!) H:\>attrib -H -S "My Folder"\"Their Folder"\*.* /S & I managed to retrieve "My Folder" and the files in the sub folder "Their Folder", however the sub folder's hidden attribute is still greyed out, is there a way I can fix the sub folder also?

Hi there and thanks for all your tips, especially jd2066 but I seemed to have hit a brick wall as when I type: (attrib -H -S "My Folder\Their Folder" /S)the cmd prompt gives: (File not found - My folder\Their Folder.) The virus that has stared my problem is called W32.SillyFDC and I use Norton 360 Version 2 antivirus, which is always up to date.

Yes I am in the H drive, it looks something like this H:\>attrib -H -S "My Folder\Their Folder /S and when I press enter the cmd gives the above mentioned response. To get into my H drive I do the following from the cmd, C:\Users\agacult>H:
H:\>

when I include "cd" it goes
C:\Users\agacult>cd H:
H:\
C:\Users\agacult>
it gets back to C drive, I don't know why. I'm using vista business on my machine

It's still giving me the "file not found - My Folder\Their Folder". I first got around this problem by following your first tip but I added [\*.*] before the , it looked something like this H:\>attrib -H -S "My Folder\Their Folder"\*.* /S, [\*.*] to clear whatever I want to clear from the folder and it's subfolders & everthing in the in it. But it's not working for the sub folder.

maybe /d switch needed

Try the command: attrib -H -S "My Folder" /S /D
That should work for the sub folders too.

This was very helpful, but when one have a lot of folders to change back this way, it takes a lot of time!

Is there not a simple program available with which this can be done?
