Viruses and Other Nasties

• See our notes from August 30 for some basic terminology

• Available: shareware.unc.edu
• Installing f-prot:
  1. Download the self-extracting executable from shareware.unc.edu/win.html, put it in a temporary location such as C:\TEMP
  2. Extract the executable to a directory you choose (the directory will be created for you if you want), such as C:\F-PROT\
  3. You can now run f-prot from wherever you installed it, e.g,. C:\F-PROT\F-PROT
  4. You periodically need to get new virus definitions. F-PROT keeps two sets of files for this, one for viruses in executable files, and another for macro viruses. You can also get a new version of F-PROT (the shareware.unc.edu version is not necessarily the most current). The file UPDATES.TXT describes where to get these files. Current locations include:
     • http://www.simtel.net/pub/simtelnet/msdos/virus/simtelnet virus directory: for all of the following 3 files
     • fp-308.zip, the September 25 version of F-PROT
     • fp-def.zip, the October 2 virus definitions (updated as needed, with the same filename)
     • macrdef2.zip, the October 20 macro definitions (updated as needed, with the same filename)
  5. Note that you need to have a program to unzip your files to get the macro and virus definitions. Both SimtelNet and shareware.unc.edu have versions you can use, as does winzip.com
