After hearing quite a bit about viruses, particularly the Internet 'Worm' of November, 1988, I have a few questions concerning prevention of virus infiltration on IBM PCs/clones using MS-DOS 3.3x or 4.01. 1) Is the possibility of virus infection limited to executable programs (.com or .exe extensions)? Or can an operating system be infected from reading a document file or graphic image? 2) Are there generic "symptoms" to watch for which would indicate a virus? 3) Any suggestions on guidelines for handling system archiving procedures so that an infected system can be "cleaned up"? Thanks for the help. Andrew D'Uva Jnet---> ADUVA@GUVAX Internet---> ADUVA@GUVAX.GEORGETOWN.EDU
