Everyone doesn't want computers infected with a virus. The question is, where the virus entered into the computer. There are two possibilities, may be infected from the Internet or external device (flash drive, memory cards, external hard drives, etc). Flash drives are external devices that are often used. When we insert the flash drive to the infected computer, flash drive will be infected with the virus. In a flash drive that is infected, will form the autorun.inf file. Autorun.inf files will work automatically, every flash drive is inserted. Setting the default operating system is windows autorun when inserted an external device. Autorun windows, used by the autorun.inf, to enter into the computer. To protect your computer from viruses, there are a few things done: 1. Update anti-virus 2. Setting anti-virus in the guard position 3. Turn off windows autorun 4. Make anti virus auto scan flash drives
Turn off autorun Windows
Win Xp : Press START - run - regedit - HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer - NoDriveTypeAutoRun - Value Data - Type = ff - OK
Win Vista / 7 : Press START - Control Panel - Hardware and Sound - Autoplay - uncheck "UseAutoplayforallmedia devices" - SAVE.
Make ESET NOD32 Anti-Virus Auto Scan Flash Drive
Using software USB Safely Remove.

You need to go to HPs website and put in the model of your computer and the operating system version ie XP or Vista or Windows 7. It will give you a list of the drivers for your system as it left the factory. Scan the list looking for sound drivers, download, install and then reboot. http://welcome.hp.com/country/uk/en/support.html
It may be that your sound is on mute rather than missing. Check out your sound on control panel, to see if it is on.
Most HPs have a utility in the Conrol panel for speaker jack output assignment, verify you have them plugged into the green jack not blue/pink, verify that the digital output only is not selected in the speaker control panel. you say built in speakers , are these in the monitor, some HPS have two outputs that can be controlled individually, again this is in the control panel audio properties utility, sometimes there is a audio icon by the clock (bottom right) that will also adjust these settings, but the "control panel" way is more reliable.
Hi, you can try to download the audio drivers here but be aware there are many 530 models, get the exact model# from the laptop bottom, also if no audio driver is listed on HPs website its because windows is suppossed to have it already or that Some audio chipsets have a an HD driver that you have to download elsewhere,because HPs driver support is lacking the complete info. tricky but fixable . If this is the case googling with the model# and word "audio" you may find the driver file in a forum somewhere.
if needed still, post the complete model for more help.
