computer virus that wont go away?

I have a bug in the windows hard drive. I cant remove it, because I need admin rights and it still wont let me through after I log in. I ran Norton, but it wont remove it - it tells me to re-install the original CD's which I never had with this PC.

Bootup takes longer and some of my keys and arrows quit working.

Sometimes (3 times a week) I have to have windows run a directory check because it didnt boot up.

Any ideas besides getting the OEM CD's? I already did an original boot, but it is still here.

    Assuming you can get rid of the viruses, you can make the restore disks using a utility on the computer, usually found under Accessories -> System Tools or under an entry for your computer brand such as Lenovo ... It will create the disks needed to perform a factory restore. Windows typically prompts you to do this when setting up a computer like this and the documentation which comes with a computer normally tells you to do this if you wan the restore disks.

    You should be able to get rid of the virus by either using a bootable AV tool or by slaving the drive to a computer with a valid AV program which is currently updated running.

    How to remove a virus -

    I) The best solution is to back up your data and perform a factory restore. Install a reputable AV program after the restore and download the latest updates before restoring your data.

    II) That not being practical for many, try either of the next two methods:

    (Please note that it is important to use one of these two methods as you need to boot and scan knowing that no viruses are already in memory. If you try and install an AV product on a machine already infected then there is a decent chance that the virus will be able to hide/relocate from the scanner.)

    A)

    1) On a clean computer, download 1 or more free bootable AV products. Five I know of are Avira, AVG, Avast, Kaspersky, and G Data.

    (There is a handy product called sardu (www.sarducd.it) which will create a flash drive/Cd capable of having multiple AV products built into it. It isn't perfect yet, but it does do the job pretty well. I keep a copy on a flash drive for whenever I go to someone's house to help with computer problems and I have a number of other diagnostic tools included as well.)

    2) Create the bootable media and include the latest virus definitions

    3) Boot the infected/suspect computer by using the bootable media and run a full/complete/deep scan of the computer using preferably at least two different ones. No AV product gets them all, but 2 different products should find and remove just about anything.

    B) second alternative method:

    1) remove the hard drive from the infected computer

    2) slave the drive to a clean computer which already has at least one AV product already installed with the most current definitions. You can do this by installing it into the case (for a desktop) or by putting the drive in an external drive case which you can get for the low teens $. These can be USB (get at least USB 2.0) or eSata - if the 2nd computer has an eSata connection.

    3) From the clean machine, run a full/complete scan of the slaved hdd. The computer should already be booted when you connect the external drive, with the AV product already in residential memory(It will have an icon down next to the clock). Then open the AV and run it on the drive. In an ideal world, you should really use two different AV products.

    III) If you are unable to do the above, then download and install an AV product and then run it at its deepest level scan. This is not the ideal method as many viruses can hide from AV products if they are already in memory and running before the AV sofware is executed. There are numerous free ones. I strongly recommend two different AV products and one Adware/Spyware product. For free AV, I would typically recommend Avira, AVG, or Avast as the installed resident (always running) AV solution and Malwarebytes as a secondary, on demand AV product which I run on a weekly basis. For Spyware and Adware, the two top performers there are AdAware and Spybot Search and Destroy (adaware is a product of lavasoft and safer-networking.org produces Spybot Search and Destroy) Both offer a free and paid version. The free version is good, the paid version offers more bells and whistles, just like with the AV products.

    Once the virus(es) is/are removed, change any and all passwords having to do with anything important like e-mail, financial-banking logins, etc. as those have probably been captured and sent to the author of the virus.

    Download Super Anti Spyware or MalwareBytes to a thumb drive or external hard drive. Do this from a friends computer if yours is being blocked from doing so by the virus. Shut your computer completely down - hold the power button for about five seconds if the normal shutdown procedure is no longer working (warning: hard shutdown by holding power button until shutdown can possibly cause data corruption - only use as last resort). Now, power the computer back on, but start pressing F8 within about three seconds after pressing the power button and keep pressing F8 until you see a boot menu that gives you the option to boot into "Safe Mode". Select "Safe Mode", ignore the other options.

    This boot will look different and take longer - don't worry, within about a minute you should be up and running. Now, plug in your external storage device with your malware killer of choice freshly downloaded and then install it. Let it run, which may take several hours, and hopefully it will find AND remove the infection. In some rare cases the infection has damaged system critical files and a restore from the factory CDs is needed. Hopefully that is not the case here.

    Good luck!

    Shut ur pc off then turn it back on and hit F8 quickly to boot in safe mode or safe mode with networking once its up go to " all programs" and see if u can delete anything that looks specious also u can try doing a system restore to an earlier date if this virus issue just started happening
