O! I wasn't sure what you were getting at, i.e. a virus or a real bug. I've seen tons of bugs in older computers that I have taken apart, but I don't think that they could do much damage. They'd be fried before they got to anything vital, i.e. anywhere near the chipset, CPU/cooler, etc... Remember PC components run really hot, hot enough to burn us, so I'm pretty sure that even with their armor, a bug couldn't take it either. I wouldn't worry.
