It must be nice to feel at home. There is still the cheaper alternative to pack light and move often, although it also requires exercising some level of good practices, everyone feels a bit better using a freshly installed OS. Build your own live-CD distro, use file-system snapshots, segregate data susceptible of containing malware, or buy new stuff in random shops you deem trustworthy, use it and throw it away. On a side note, as we've seen recently, using untrustworthy sources of software like npm will without a doubt affect your level of security. There is no complete and simple solution, AFAIK.
