thanks for your interest
no need to be shocked
all unmeasured:
my vista computer runs faster with v5 than v8
eset v5 interface responds faster
bought multiple licences so can also run v5 on a Win2000, mostly offline, notebook. Eset unpacks more files on this, ie fewer blue NSIS archive damaged messages with W2000 than with my vista computer.
from my memory there is an extra option in v5 firewall than in v8, ie full automatic mode remains an option even after setting your own rules in v5, but i'm not reinstalling v8 to find out.
i run regular scans, but if I am jeopardizing my security with v5 i would be happy if someone would tell me why.
i hope this feedback helps.
