Yes. Simple rules of the thumb:
1) use a clean rescue CD to boot from it (to be safe from rootkits).
always do a cold boot (from power off state), just in case
2) use the tripwire binary from the CD to build a database of
signatures of the important files on your computer and store it on
a floppy (it will usually fit, if you compress it)
3) from time to time, or if you suspect a compromise, boot again from the
CD and check the integrity of the files against the signatures on your
4) NEVER EVER rewrite your database (or insert the floppy disk containing
it write enabled) on an untrusted host
