WordPerfect® 5.1 for DOS

Problem

Solutions: A customer running a newly installed 17/09/91 British (UK) version of WordPerfect was using a program called VSAFE.COM, a TSR installed by PCTOOLS V7. When he started WordPerfect, he received a dialog box telling him that the WP.EXE had been changed and listed the following options: Stop, Continue, Reboot. Stop took him back to the WordPerfect Library Shell where he had started from, and Continue loaded WordPerfect and displayed the message each time he entered WordPerfect. He corrected the problem by selecting the Update option in VSAFE to update the *.EXE information.

This message occurred because the antivirus VSAFE program checked all the *.EXE files for any changes. When the customer installed the new WordPerfect program disks, VSAFE detected the difference in the WP.EXE file as well as SPELL.EXE, WPINFO.EXE, etc., and activated the alert message.

FYI:
Another customer who was using VSAFE as a TSR received the message "Program Trying To Modify System Memory" while using the arrow keys to move between cells in a table. The problem usually occurred after rewriting the screen using Ctrl-F3. This customer solved the problem by using VSAFE as a stand- alone program to check the hard drive or diskettes as needed rather than as a TSR.

Virus detection TSRs look for certain typical virus behaviors such as modifying certain memory locations or writing to the hard drive in certain places such as the boot sector or FAT. Some programs do these things as part of their normal operations and are not viruses. To avoid incorrect warnings such as the ones above, use stand-alone virus detection software rather than TSRs.
