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.
