Thanks for your information re: "ping" necessities and I see now why Lavasoft found these files - BOTH doing their jobs, I guess!
I apologise for any implication and as I said I'm very satisfied with Avanti!
After reading some of the horror stories, I am happy that my download, installation, compatability are trouble-free and IE/Outlook/MS et al, are all cozily in bed with my Avanti!
I have absolutely no problems, no crashes, no freezes, no re-boots, in fact nothing to report.
Look forward to ver. 4.2
