VHD VHDX and other virtual hard drives

Jump to solution

Can anyone tell me how McAfee Virus Scan handles VHD, VHDX and similar format files. Perhaps they are temporarily mounted and treated like a drive.

The reason I ask is that I bought a new computer a few weeks ago. When the new one arrived I did a full scan and then made VHDXs of its C: and 😧 drives. I left the VHDX files on a drive in the new computer. I am suddenly getting a virus alert from one of the VHDX disk images. 

 

Is this likely a real virus or is it likely to be a false alarm?

Lifespan of your SSD won't depend on the disk format you will use, but on the load that your VMs will put to it. I would say there is nothing to worry about, unless you are going to run write IO-intensive applications for 24/7. In that case would need a server grade mixed-used or write intensive SSD.

My original question was asking whether vhd, vhdx etc. files get scanned for viruses. The answer I was given was that they were. However when I scan a large vhdx file. say 40G, the return is almost instant saying no virus. I can think of two reasons for this. First, when a large vhdx is scanned a hash is saved and if it hasn't changed there is no reason to scan. The second is that McAfee doesn't scan vhdx files. If the second were true then a small change would force a scan that would take time, also just computing a hash requires reading the whole file but the return is almost instant. 

 

My conclusion is that McAfee does not scan virtual disks.

That isn't my question. Wear on the drive is nothing to do with what I asked. I am trying to find out whether McAfee scans within vhd, vhdx etc. My conclusion is that they do not because if I scan a single vhdx file I get a no-virus response faster than would be possibly in which to read the file. Also they can't be using a hash since it still requires reading every byte which takes more time than than taken to scan the file.

VDMK is for vmware VMs. VHD and VHDX is for Hyper-V . VDI is the virtual disk format for Oracle VirtualBox. So disk format will depends on the product you will use to run the VM. Lifespan of your SSD won't depend on the disk format you will use, but on the load that your VMs will put to it. I would say there is nothing to worry about, unless you are going to run write IO-intensive applications for 24/7. In that case would need a server grade mixed-used or write intensive SSD.
