If Malware bytes will not catch it, you can also try Superantispyware

Thanks for the second. I must get hold of it and check it out.

 

I can't remember whether Symantec have a free on line scan system or not -- do you know? Or do they only have the $99 special? <wg>

I am trying to fix a friend's computer. It's one of those neglected computers that had no antivirus or antispyware programs loaded on it and users just  clicked on everything they saw. As a result, there were so many popups that it was unusable.  First, I tried to remove the spyware with Ad-Aware, but Ad-Aware would not install. I kept getting error message with msiexec.  So, I tried a product called registryeasy which removed lots of empty registry keys, etc.  I also tried a product called Spyware Terminator, which said it found 1100+ instances of spyware and 88 viruses, trojans or worms.  After rebooting, I could not run any executable without receiving a message that 'rundll' could not be found. Basically, it seemed like all of my windows apps were hosed.

I then reinstalled Windows XP (SP2) by booting from the Windows cd.  I also purchased Norton Antivirus 2009 for my friend but I can't install NAV. NAV tells me it will only install on XP SP2 or later, but the cd is for SP2. I've also run Windows Updates and updated windows. The only way I can get SOME programs to run is by right clicking and selecting 'run as' and UNchecking the checkmark that indicates 'prevent my computer from running....'.

Anyway, since I can't install NAV, I tried booting from the cd. It runs a program called NAVDX but it's done in a few seconds and looks for virus defs in the A drive. I dont think it's scanning at all.

So, long story short, HOW can I get NAV to scan this computer and remove any remaining viruses?  I feel like this computer is totally hosed.  Thank you for anyone's help and advice on what to do here.

Sorry, I meant NAV 2008....

Thank you so much for your speedy reply.  I've been able to successfully run Windows update on my newly installed Windows XP Home, and it is now up to SP3.  However, it seems like I either have a virus that is preventing any executables to run, or my registry is messed up.  I can't run Internet Explorer, or any .exe, INCLUDING the NAV setup from the disk. I get an error from NAV saying it needs to install a updated version of msiexec but it cant connect online to get it so the setup terminates.  Does anyone know of a sort of registry fixer program or a way I can get NAV installed?  Thanks again! :)

OK That's a relief that it's NAV 2008 .....

 

Did you get NAV 2008 on a CD or by download? If you have it on a retail CD you can run an antivirus scan from the CD without installing NAV -- OK the virus definitions probably date back to August 2007 but that 's better than nothing. 

 

 

<<  Does anyone know of a sort of registry fixer program  >>

 

Don't even think about it unless you want to have more problems than you start with -- how do these programs think they know more about what goes on in the registry than Microsoft does (if even they know!)?

 

msiexec.exe is a valid Windows file but from a quick Google it is spoofed by some malware.

 

Do you have a retail CD of Windows XP? If so it might be worth running the sfc command line utility since that checks Windows files for errors or if they are missing and replaces them from the CD.

 

If it is malware then it might be worth trying Malwarebytes Anti-Malware which is a free and very good malware scanner that you can download -- click on that link. Don't be put off by what the site says about paying for it -- that's for a version that runs continuously in the background which most of us don't want or need. After you download and install it, click on the Update now button to make sure you have the latest definitions.

 

Hope that helps but keep an eye for messages here since others know more than I do.

 

Stick around and you certainly will end up with NAV properly installed, I'm confident.

thanks again.  I did purchase the NAV 2008 cd, but when I run the cd at boot, it seems to check for about 3 seconds and says it didn't find anything. It does say it's looking in A: for virus definitions, so I think I will try to find a working computer with a floppy drive and try to download the latest NAV 2008 virus defs to a floppy and try that approach.

I will also try to run sfc and try the Malwarebytes and report back. thanks so much!

Hi Huwy

 

You mean this?

http://security.symantec.com/sscv6/default.asp?productid=symhome&langid=ie&venid=sym

If you booted from the cd, the cd is A:  Any definitions should be there.  Make sure you are not booting from C:

 

It is always difficult to clean up a messy computer ....

 

One thing: I note that you say:

 

<<  I also purchased Norton Antivirus 2009 for my friend but I can't install NAV. >>

 

Are you sure it was NAV 2009? It is not on sale yet but is on a public beta as you'll see in the other main section of the boards here. If you have bought NAV2009 someone has sold you a pup and I know Norton will want to know about it.

Regarding the first part of your experience, I think you can now see how dangerous some of these "fix-it" tools are. There is no way they can know enough about Windows and its inner workings to safely clear "unused" bits of the registry for example. And some of them are scams trying to sell you something that either does not work or causes harm.

 

I'm glad you made a new clean install. We can't deal with the installing NIS2009 problem until you confirm whether it was 2009 or 2008 so let us know about that first please.

 

There are some really experienced people here on cleaning up and there is a very good free program called Malwarebytes that you can download, intall and run. Don't be put off, if you go for it, by the references to paying. What you download is free to use but if you pay then you can have it running in the background continuously, which most of us do not want, especially if we have NIS installed and running.

 

There are also reputable websites one can go to get an on-line scan in case some malware is stopping the install.

 

But hang on a while for some help
