Infection Through Software Installation

Many people don't realize this, but viruses are sometimes spread through software distribution. While usually this happens with low-budget freeware or shareware products, it is certainly not unheard of for viruses to be found even on commercial, shrink-wrapped software! This is very rare, and I don't usually bother scanning commercially-purchased software for viruses, although some people do. Other than scanning, there isn't much you can do about this tiny risk (well, you could decide to never buy any software, I suppose.)
