Antivirus software crashing

If you are running a computer that has Windows 8.1, Windows Server 2012 R2, Windows 8, Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 SP1 installed, and your installed antivirus software, such as Kaspersky Antivirus software, is not able to check whether a file is digitally signed or not, but instead stops responding when it does, then visit the link mentioned at the end of this post to download and apply the hotfix.

Says the KB article:

You have antivirus software such as Kaspersky Antivirus software installed on the computer. The antivirus software can check whether a file is digitally signed. You receive a specifically crafted or damaged signed file through an email message, an Internet download, or by any other channel. In this scenario, the antivirus program does not check whether the file is digitally signed, and then the program stops responding. After that, the computer is unprotected, and the antivirus software cannot be restarted, even manually.

The hotfix will, inter alia, update the Microsoft Trust Verification APIs Wintrust.dll file. You can download it from KB2903025.

If you have a computer that’s running Windows 8.1, Windows Server 2012 R2, Windows 8 or Windows Server 2012, and you have antivirus software such as McAfee Antivirus installed on the computer, and when you perform an on-demand virus scan, your on-demand virus scan freezes or hangs, request a hotfix KB2904100.

You will be required to restart your computer after you apply this hotfix.
