Every few weeks, I am getting an error from Prevx on boot which stops Prevx from running. The messages says: Prevx.exe application error The instruction at 0x0043fc0d referenced memory at 0x02875001. The memory could not be read. Click ok to terminate the program. I cannot then remove the program through add remove programs & the only way to fix it is for my IT support to run forceuninstall.exe, then reboot & then remove Prevx from add/remove programs. Then reboot & install Prevx again - which then works for a few weeks. This is now the 3rd occurrence of this problem. Any fixes please?
