I just wanted to share some knowledge with you all as it took me a bit of time to uncover on the web and is quite astounding. I was getting invalid boot.ini messages on my PC and after restoring and rebooting several times, it kept disappearing. Suspected Virus, Trojan or Malware and used all the tools to scan but found nothing. Was rolling up my sleeves and preparing to get the serious loggers and tools out when I found a discussion that concluded it was a bug with Ask.com Toolbar, so removed it and all is well again.
Unbelievable but important to share.
