I posted a problem at Wilders Security and they suggested I post it here. A person on that site was having problems with a Dell i5 running Win 7 Pro, when running Malwarebytes on Truecrypt containers (encrypted logical drives). This was causing the "blue screen of death" when when scanning with Malwarebytes. I posted that I was having a similar problem. It is very repeatable if you want more information. I understand in advance that Truecrypt is a special case, so thanks for your time. Here is the post on the other site (Mod: delete URL, it is FYI): http://www.wilderssecurity.com/threads/malwarebytes-and-truecrypt-bsod.365207/#post-2388841 Here is the text from the original post (referral cross post): Thanks. Love the product. In addition to the above post at the other forum, I can supply logs that might help. The good news is that I know how to reproduce the problem!
