Hi
I hope this is the right forum, its changed in here, Ive not been in a while.
I have some kind of nasty virus.
It made all my desktop icons dissapear, and all my programme icons dissapear.
I somehow managed to do a system restore.
Then about half of my folders where 'hidden'.
Annoying as they are all greyed out even when 'display hidden files' or folders is selected.
I highlighted all my folders in my documents folder, And changed the properties off all of them at once to 'not hidden', and 'not read only'.
Otherwise it would take me years to do each one individually.
But I've no idea if its safe to have all files/folders as not read only?

Also, this svchost virus is still trying to attack my computer, as my avast keeps saying it has to keep blocking it.

This is avery nasty trojan, i think it may have caused caused irreperable damage to my system.
I hope not, As I am on a netbook, and cannot run a recovery disk.
It has a recovery console built in,(hewlet packard), but if i ran that, I'd lose everything on here, and it took me a lot of work to get it set up how it is right now.
any ideas?
Thanks

Sory, its just getting worse.
now i have a blue screen crash very frequently.
'Bad_pool_header'

eitehr that or th escreen just freezes.
WE are in big trouble.
I'm now trying to just restor it to factory settings.
But i cant even get that to work.



Its an HP Mini netbook.
I'm trying to do this, but it wont work.
one possible solution is:
''1.Right-click on "Computer" icon and select manage.
2.This will launch the Microsoft Management Console.
3.On the left side of the MMC, click on "Disk Management" and it will show you all of the partitions.
4.Right-click on the "HP Recovery" partition and select "Mark as Active Partition."
5.When the warning prompt appears, select "Yes" - Reboot the notebook and it will automatically boot into the Recovery Manager (without having to press F11).''

BUT i cant mark it as an active partition.
When I try, it says:'This request could not be perfomred becasue of an I/O device error'
please help.
If i cant restore my netbook to factory settings, its only use it in the dustbin.
thanks

I'm sure if i can reset it to defaults, it will be ok.
There is a partition with 10gb worth of stuff on it, just for reseting to factory setings
but how to run it?
