Cannot run nor uninstall or re-install Microsoft office 2007

A customer brought a laptop to me that she said when she plugged in her flash drive and transferred her document to her laptop all of her icons that are associated with office 2007 changed to blank and when she attempt to open the files she gets an error "The operating system is not currently configured to run this operation"  I ran a malwarebyte scan and it showed no malware.  I ran a scan with Avast and it showed no virus.  

    I attempted to re-install Office 2007 but I get an error "an error accured during the installation. setup cannot continue"   I dissabled Avast before attempting to install Office.

    I attempted to uninstall Office 2007 but the uninstall failed also
    I attempted to go into save mode but I get the same results
     Is there a virus or malware in the laptop that avast and Malwarebytes cannot detect?
    I am ready to wipe drive clean and re-install if necessary, but I need to know how to keep this from happening again.

Try using Microsoft's Office Removal tool to wipe the installation of Office from the system and then re-install.

(check "method 2 - Microsoft Fix it")

From the sounds of it the Explorer file associates have been changed so when you doubleclick on an office file extension it doesn't actually open Office. A reinstallation of Office 2007 is definitely a good idea.

If this happened all of a sudden after inserting the USB key it could have been caused by a malicious program which utilized the USB Autorun vulnerability in Windows. Here's some information on this vulnerability and how to protect yourself from it:

You might want to check the file associations in Windows to make sure they are correctly associated. Open Explorer, locate a Word document or Excel spreadsheet, right click, choose Open With and see if the expected program is selected as the default program to open this kind of file. If not, choose the program executable file and tell it to always use this program when opening this kind of file.

Also has a more recent version of Office been installed, or any newer components? This can sometimes prevent Office from running correctly.

Avast and Malwarebytes are good but not necessarily 100% in detection. New strains come out every single day and many machines are vulnerable at least for a short while until the definitions are propagated.

I have found that USB-set is an excellent way to prevent autorun as a vector for infection.

WHen you ran the scan did you scan the usb stick as well. If you do not want to install other malware virus detection software, you can run some of the online virus scanners. There are quite a number of different online scanners that will scan the computer without having to install them.  There is no antivirus or malware software that will detect 100% of the infections out there. Some detect infections better than others and that changes as well.

Can you give me a good antivus program to run without installing?
 I do not have the flash drive but I am sure that my customer will be glad to give me the flash drive.

McAfee Stinger detects and removes certain infections. It is available, with instructions, here:

McAfee Getsusp is also available and detects many new threats.

McAfee Rootkit Remover is another free tool that runs as a standalone - as all of these tools do.

The rootkits removers I review in my article are all free, you can use many of them straight from a USB stick.

Just want to thank all of you for your excellent help.  I ran the avast antivirus scan, malwarebyte, pulled the hard drive out of the laptop & plugged it into my computer & ran avast scan, ran all three of mcAfee scans and never found a single thing,  I finally use the Microsoft office repair and diagnostic tool and it corrected and brought everything back to normal.  I then downloaded & installed that USB-set that frosty555 suggested.  I was running out of time because the customer was in a hurry to get her laptop back, so when everything was back to normal and working fine I called it quits.  But I plan on experimenting with all of the other suggestions that were given to me.  Thanks again.
