Hello,
The issue should have been resolved in Maintenance Patch 1 for Maintenance Release 5 (MR 5 MP 1)
"Faulting application Rtvscan.exe, version 10.1.5.5000, faulting module I2ldvp3.dll..." appears after installing Symantec AntiVirus 10.1.5.5000
Fix ID: 833133
Symptom: After you install Symantec AntiVirus 10.1.5, you see the error "Faulting application Rtvscan.exe, version 10.1.5.5000, faulting module I2ldvp3.dll, version 10.1.5.5000, fault address 0x000056ab."
Solution: Changed the code to prevent the null pointer access that causes the application fault. A workaround for this problem is to run LiveUpdate after you install a Symantec AntiVirus server before you add clients to the server group.
However, check the following Articles:
