I'm hoping somebody here might be able to help, as I am devastated right now. I'm seriously an emotional wreck after the events of the last couple of days.

I've loved my HTC EVO 4G for about four months now. The android operating system is awesome.

I took some pictures to give away a free bed and computer desk, and upon plugging my 4G into my computer to upload them the phone immediately turned off. I've used this USB-PC connection multiple times before, I don't know what changed. I didn't think much of it, I turned the phone back on and tried again. It turned off again.

I turned the phone on again, and the battery drained like CRAZY. I'm talking full to empty in 10 minutes. It also heats up badly, the back is extremely hot to the touch. I've tried three OEM batteries, two of which I did NOT have in the unit when plugged into the USB port, all with the same results.

I ended up finding an HTC EVO 3D used for $260 which worked perfectly. I was so excited! I took it home and plugged it in to my computer using a different USB cord AND a different USB port just to be safe, and it turned off. The EVO 3D won't even turn back on, I get nothing on the screen and it doesn't even recognize a wall charger now.

There is obviously something wrong with my computer, but does anybody have any idea what I could have fried on these two phones? I don't understand at all why my computer fried these phones, I used a port on my Rosewill card reader that fried the EVO 4G and the port I used on the EVO 3D was on the motherboard. Whatever happened, now I'm stuck with two amazing phones that don't work. Any help at all would be greatly appreciated, I'm pretty experienced at fixing things but I don't even know where to start on this one.

Thanks!

And the PC runs fine, otherwise? How about other USB devices?

I just don't know about the virus thing. Android is Linux that runs apps in a virtual machine, very isolated. So viruses made to work in Windows (I'm assuming your PC is Windows) won't work on a Linux device.

Sounds like some sort of hard short to ground or static buildup. Either way, I'd be willing to be the problem is in your power supply. Specifically, the grounding pins. Or your 3.3 volt rail is messed up.

Either way, if the devices don't power up, they're shot. Especially if you changed the batteries and they still malfunction. Although, you should be able to access the bootloader and see if the devices get hot by just sitting in the bootloader. That would eliminate the possibility of it being a software problem. Pull the battery, count to 10, reinsert then hold Vol down + power until the bootloader appears. Let that sit for 5 minutes and see how hot it gets.

EVo 3D should be under warranty...

and you said you got the evo 4g a few months ago.. so it is also under warranty
