What to do if my laptop (hp pavilion) has virus?

the screen went blue and there it was written spy ware detected. when i used avg the words were gone but the blue screen is still there. and i cannot access the control panel to change the display - it was saying, that access was disabled and have to check with the administrator

1. The blue screen is called the screen of death. It is infected by a virus that attacks your hard disk. Your only option is to re-install the OS.
2. Id suggest a support forum, this is usually a multi-step process that rewquires other people to look whats going on at each step. A forum is the best place to do this. Google Computer support forum and im sure youll find a lot. And - make sure you don pay for the support, this kind if thing is free all around the internet!
3. I would try going into safe mode and then try to run a virus scan. Most AV softwares that you bought and have a CD for are bootable and can run in DOS mode
4. this is the work of a deadly virus...something much advanced than a trojan horse probably...so try calling a comp expert to fix things or if the screen luckily comes on, try downloading a real strong anti-virus like norton 2008
5. hp supplies you with system recovery cds..use them to restore your computer to factory shipped condition
6. This should fix your Control Panel access. This entails going into the Registry, and that's always risky. Some ground rules for using it: 1.Do NOTHING in Regedit other than what I detail here. 2.Commands in Regedit take effect immediately and have no Undo capability. We'll create a backup file, but some mistakes in editing the Registry can prevent successful booting up, making that file useless. 3.If you think you made a boo-boo during the editing, IMMEDIATELY, WITHOUT GETTING OUT OF Regedit, click on File->Import, find the backup file and import it. That will put the registry back to the way it was before you edited it. The procedure: 1.Click the Start->Run menu item. 2.In the text box, enter regedit.exe and press Enter. 3.For safety, we're going to backup the registry in a .reg file. This will be a BIG file (think 60+ megabytes). Click the My Computer icon in Regedit’s left-hand pane. 4.Click the File->Export menu item. 5.Give the file a name and save it as a Registration File somewhere you'll be able to find it again if you need it. 6.Using the left-hand pane, navigate to this key: HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies\ Explorer 7.In the right-hand pane there might be a value named NoControlPanel. If so, delete it. 8.Using the left-hand pane again, navigate to this key: HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies\ Explorer 9.In the right-hand pane there might be a value named NoControlPanel. If so, delete it. 10.Try to bring up the control panel. Good luck.
