Yes. A few reasons why:
1) If an antivirus program doesn't have current definitions/signatures, it may not see infected files on the computer.
2) Some viruses actually attack and modify antivirus programs, especially older ones that aren't updated, making them indicate all clear when there is still an infection.
3) If certain parts of automatic scanning or real-time protection are disabled (i.e., not scanning compressed files, only scanning certain types of files, and so on), the antivirus program will never detect problems in the areas/files excluded.
4) Some viruses hide in the backup files created by Windows' System Restore function, and many antivirus programs can see the viruses but not remove them.
