Installing Avast Free anti-virus on a VirtualBox VM generates a blue screen error on windows.

[MFS68]

Dear,

Good Morning.

I'm trying a few days ago to install Avast Anti-Virus Free (​https://www.avast.com/index) on a virtual machine that has the guest operating system Windows 7 Home Premium 32-bit, with Service Pack 1 and all installed updates. Intel (R) Pentium (R) Dual Processor CPU T2370 1.73Ghz and 1.22GB of RAM. I can only get to the end of the installation and even browse the program through Network - enabled Windows Security Mode. When I restart the machine to enter the normal mode the blue screen of Windows appears and then the screen "Startup Correction" appears. The machine only returns to normal after it is restored to the previous state of the machine before installing Avast. I have already used the chkdsk / F / V / R / X / B and sfc / SCANNOW commands to try to fix some possible errors in Windows, but nothing worked. My host machine has the 32-bit Windows Vista Home Basic operating system, Service Pack 2. Intel® Pentium (R) Dual Processor CPU T2370 1.73Ghz and 2GB of RAM. Also with all Windows updates installed. I am using the Oracle VM VirtualBox version VirtualBox-5.1.12-112440-Win.exe on the virtual machine. I have a windows dump that has recovered from an unexpected shutdown. But a screen print of the error message that Windows presents, as well as the VBox.log and VBoxHardening.log files, which I will be sending to you.

I extracted from the VBox.log file the following error message reported below:

00: 00: 40.351671 ERROR [COM]: aRC = VBOX_E_IPRT_ERROR (0x80bb0005) aIID = {02326f63-bcb3-4481-96e0-30d1c2ee97f6} aComponent = {DisplayWrap} aText = {Could not take a screenshot (VERR_NOT_SUPPORTED)}, preserve = false AResultDetail = 0   

Would you be able to tell me if VirtualBox has any incompatibility with Avast Free Anti Virus?

Invalid and Duplicate of #8545.

Avast requires VT-x availability on the Guest (or anything else that gets installed on). This VT-x availability was not an option until 6.1.0beta.
