Most of the time when my family members plugged in a flash drive to my computer, it would infect my PC instantly because the USB drive was already infected with viruses and trojan from various locations like internet cafe, public pc and so on.
i'm really getting so annoyed to the point that I want to buy pc to all of them, but it would be very expensive, I hate it when someone plug in a dirty usb drive into my pc and it got security alert.
I don't plan to drop much on it as I only have 450-600$ to spend on a dedicated PC for scanning virus. I hope that this should be sufficient for scanning a thumb drive.
What kind of specs should I be looking for? Multicore CPUs? SSD? Strong single core cpu? High frequency Memory?
