I downloaded F-PROT for DOS. I also downloaded & installed Tech-Protect Virus Protection System, which is a discontinued GUI for F-PROT for DOS. Also downloaded & installed Overself Research Anti-Virus Definitions Updater for F-PROT for DOS Version 2.61. These are all freeware for the home user. OK the questions. I've looked around on all 3 mentioned sites below & here at Wilders & the net. Is F-PROT for DOS just an on demand scanner & not resident? That's what I thought. But in the app Tech-Protect, theres an option to Enable Tech-Protect Monitor. The Tech-Protect Monitor seems to add real-time or resident functionality to F-PROT for DOS. Does this really add real-time or resident functionality to F-PROT for DOS? Given the explaination of Tech-Protect discontinuing their app. Is it possible & or wise to use as one's only AV? The footprint is very small. I'm confused & would like some insight from the experts here. Thanks. http://www.f-prot.com/products/home_use/dos/ F-Prot Antivirus for DOS is FREE for use by home users on personal workstations Combining the long experience with the latest technology F-Prot Antivirus for DOS is the ideal second defence antivirus protection.

F-Prot Antivirus will scan inside compressed files, as well as in Word documents and Excel workbooks. http://www.tech-pro.net/techprotect.html Tech-Pro's own Tech-Protect virus protection system, which used F-Prot for Dos as a virus scanning engine, is no longer available. We were receiving an increasing number of reports of problems with F-Prot for Dos. F-Prot's developers Frisk Software International have never supported the use of F-Prot for DOS on Windows NT-based systems (including Windows XP) and so these problems are not solvable - they were caused by trying to use F-Prot for DOS to do something it was never designed to do. It cannot handle long paths or certain filenames that may occur on systems that use the NTFS file system, and it cannot scan executables that use the new Windows .NET platform. We felt that we were doing a disservice to ourselves, Frisk Software and our users by continuing to offer this product. Accordingly, Tech-Protect has been discontinued and is no longer supported. Existing users, who are happy to continue to use Tech-Protect despite its shortcomings and need to reinstall it, may download the last released version of Tech-Protect. http://www.overselfresearch.com/software/downloads/avdefsupdaterfprotdos/ Do you use F-PROT for DOS or plan to use it in an emergency situation?
