Can NOD32 disturb communication with an Psion workabout (handheld device) without communicaton viral code (of course)? This device communicates via RS232 on YMODEM protocol in a custom made application. Communication was broken, no log event found in NOD32 logs. After exclusion of the target directory in IMON, communication was runnig normally. Is this a coincidence or does it make sense?? Does anybody know?
