You could in principle note down everything you have installed, perform a system recovery to set the computer back to the factory, from either the Recovery CDs you made when you first got the computer, or from the Recovery partition on your hard disk (which should not be infected) You would then have re-install the other software that you wanted from scratch, either from the original disks, or downloading it from the internet. This includes updates, drivers etc.
One way of reminding yourself of what software you have is to keep a copy of your infected disk to look at (remove your new disk before looking though).
The other thing you could do is try to remove the virus. , either by returning the computer to a professional to do for you, or by yourself, or sign up to one of the many the forums that exist on the internet who will help you e.g.,,,, www.techsupportforum or one of the many others. Volunteers will help you, and direct you to use virus removal tools. It may be a long job and may not always be successful - sometimes the only thing to do is start from scratch (erase your hard disk: try NOT to erase the recovery partition though. If you have lost the recovery partition, and you did not make recovery CDs, HP may supply you with a set of recovery disks if you ask them nicely and give them loot.
Let us know how you fare (in a couple of months....)

    Two other things: always back up your work (saves the loss of thress years' files); and this virus may be removed might be be removed by scan wih Avast, AVG, or (Mcrosoft's) msert tool or one of the other common ones. You just don;t know until everything agrees that that it's clean AND you have no symptoms. 13.April.2013

SOURCE: HP a6750f monitor goes to sleep without warning

Well FIRST take it back and make that "Repairman" work on the problem until solved at NO extra fee. What has been done is NOT professional. Had you come to my shop, this wouldn't have happened and if it did, it would be remedied without cost, and would be worked upon until fixed. The same must apply here. You paid good money for a FIX NOT OS replacement I suspect you have a faulty component,maybe Video card maybe WiFi card etc. Please do NOT accept a run around. Try the "Honey"approach first, then "Vinegar"... if, you get any BS, from them/Him. I am sorry on behalf of us professionals.

Netbook only loads up to the desktop page but will not go any further my boy downloaded a wallpaper last night and it hasn't worked since, i can't get into the control panel to uninstall it

If you cannot get into Control Panel, I suggest a rogue scareware anti-virus has been picked up.

It attaches easily, and is easily picked up off of the internet.

The rogue scareware anti-virus I'm referring to is a form of MS Anti-Virus.
Has been out for years, and has changed it's name over the years.
It takes over Administrator settings, and will not let you access them.

Control Panel, Task Manager, Windows Explorer, Administrative Tools, and so on.

Info on MS Anti-Virus,

As you can see MS Anti-Virus has changed it's name over the years. This is an older article, and new names have not been published in it.

MS Anti-Virus will pop-up with what looks to be genuine Microsoft wording. It leads a person to believe it is a genuine anti-virus from Microsoft.

It can also pop-up, and start attaching itself before you know what is going on. Could have popped up for your son, and he was too scared, or didn't know what to do.
(Press the Power On button in, and hold it in for a count of 10 seconds. Turns the computer off.
Then install a CD copy of Malwarebytes to wipe it off, when you go to restart the computer again)

Kick it to the CURB!

I suggest using the free version of Malwarebytes Anti-Malware

On the internet you will see people hawking one anti-virus after another.
All claim it is the best one.
I have used Malwarebytes to easily rid MS Anti-Virus, and KNOW it works.
I use Malwarebytes all the time. (And CCleaner)

Info on Malwarebytes,

There is a free version, and a paid for version.
I suggest the free version. has both. I have downloaded the free version from them, but it has a constant reminder to purchase the paid for version. Nothing wrong with that, but there is a free version available without the constant reminder, from

{The paid for version turns on automatically when the computer turns on. Checks websites as you view them, your email, and a host of other attributes. It is also a commercial version.

The free version turns on when YOU turn it on. Just remember to use it on a scheduled basis when you think it is necessary. The free version works just fine }

On the Cnet link above left-click on Download Now (9.03MB) in the rounded rectangle.
Takes a few seconds before a small window comes up -
Opening mbam-setup-

{Took 9 seconds just now}

Left-click on the empty circle to the left of - Save File
Another small window will come up.
In the heading of the window is worded where the file will go.
Write it down.

In the wording there may be Desktop, or My Documents, or Downloads.
(Desktop, Documents, Downloads, for Vista and Win7)

Desktop: The file will be on your Desktop screen

My Documents: Left-click on Start, then on My Documents.
(Windows logo button, then on Documents, for Vista and Win 7)

Downloads: Left-click on Start > My Documents, > then DOUBLE-click on Downloads.
(Windows logo button, Documents, double-click on Downloads, for Vista and Win7)

When you see the file name Double-click right on it.
Follow the easy instructions. (Got questions when installing, post in a Comment)

After you have installed Malwarebytes, open it up. (Run Malwarebytes)
Perform a Full Scan.

When Malwarebytes has finished, close all windows, restart your computer.
Do you have access to Control Panel now?

There is one more thing to perform.
Turn System Restore off, run Malwarebytes one more time.
Then turn System Restore back on, and create a Restore Point.

System Restore not only restores the files on your computer, it also restores the virus.

In Control Panel click on Performance and Maintenance.
Go to the far left side of the screen, and left-click on System Restore.

When System Restore loads, go to the left side, and click on System Restore Settings.
In this window click on the empty square box to the left of -
Turn System Restore off.
Go below, and click on Apply. Now click on OK.

Run Malwarebytes.

When finished restart your computer.
Go back to Control Panel, Performance and Maintenance, System Restore, System Restore Settings.

Click on the square box again. Removes the green checkmark.
Click on Apply, then on OK.
Go back to the System Restore window.
Click on - Create a restore point.

If the wallpaper is a program you can delete it from Add/Remove Programs in Control Panel.
You can also use Windows Explorer. (Not Internet Explorer)

Click on Start, hover your mouse cursor on All Programs.
Go up to Accessories, then over, and down to Windows Explorer.

I also suggest you open your hidden files and folders.
These are files hidden from the user so that basic necessary Windows files are not accidentally deleted.

DO NOT delete any files unless you are Sure about what you are doing. You can look around in Windows Explorer all day, and not harm anything.

Go up to the top header. Left-click on Tools. Now on Folder Options at the bottom of the list.
Left-click on the View tab.

Under the subheading Hidden files and folders, left-click in the empty box to the left of -
Show hidden files and folders

Now go below, and click on Apply, then on OK.
A Windows 'Squawk box' will come up.
Tells you what I already have.
It's okay.

When Windows Explorer opens up, it automatically shows the My Documents file 'tree' opened up.
It also shows the contents in the larger window to the right.
I like to close the file tree for My Documents. Makes it easier to see what you are doing.
Click on the - sign to the left of My Documents.

Now left-click on the + sign to the left of My Computer.
Click on the + sign to the left of - Local Disk (C:)

Click on the + sign to the left of Programs.
Is it listed?
Click on the + sign to the left of it then.

On the right, right-click on each file name one at a time. In the list that pops out left-click on Delete.
When all files are deleted go back over to the name in the file tree to the left.
Right-click on the name, delete it.

For additional questions please post in a Comment.

Seem my netbook window 7 hp 110-3000 dont have a desktop background why i cant set up my personal background why please help tq

If you are running Windows 7 Starter, you cannot change the desktop background as easily. There is a software utility to do this, available here:

Follow those instructions, and you'll be able to change your desktop wallpaper the normal way.
If you aren't using Windows 7 Starter, or you used the patch that I linked you to, then right click on your Desktop, and then click on Personalize.

Daughter can not open any document and doc on flash drive, says there are zero files when trying to open, but if you do to control panel it says there are files on the flash drive

This sounds like a virus deed. There is a virus that attacks Office files and basically wipes their content.
Make sure you have a secure system, clean of viruses, trojans and any security holes (here's how I do it). Then, get some free data recovery application and try to restore/copy the files off the USB key. Here's a list of free tools I've used Easeus to save 1.5TB of data, so I know it works well. But you may want to try them all out and see which one does the job best.

Need drivers, reloading xp. No disks available. Can't locate p/n to get the correct drivers from Gateway.

Hopefully you have not tried to reload XP yet.
Back up the current drivers with Driver magician lite.
CD/Floppy disk/Mem stick.
Then have at it. :)

Majority of the INF files are found under C:\Windows/INF
Even then installing OVER your existing XP the drivers should still be there. Unless you tell it to wipe and start from scratch.

Some viri and spyware programs can be so difficult to get rid of or cause so much damage. It is easier to wipe the system and start over.
If this is the case:
Ounce of Prevention is worth a pound of cure:
Spybot search and Destroy
Comodo firewall
ZoneAlarm Firewall
(Basically anything but the windows firewall)
Tip: Only run one firewall!!!!

AVG Free virus protection
NOD32 Virus protection (excellent but not free) 30 day trial however.
IObit360 (Highly recommened and fast!)

Good luck!
