Hi, I have a windows 7 64 bit here with msft word 07 associated with all programs, it even loads on boot. All icons have changed to word also. I thought for sure it was a virus, but offline root scans and regular scans have found nothing. Process explorer, malwarebytes (normal mode)SAS, webroot, kaspersky, tdss, hijack this, nothing. I tried file association fix, sfc, and office diagnostic. Any clues?
