I tried to update my legitimate NOD32 4.2.40 to v5 but could not uninstall v4 because the appropriate msi file was missing. At some time that file must have been inadvertently deleted from my computer. As well, there appears to be no uninstall file in the ESET directory. Any ideas would be much appreciated. I apologise if this has been dealt with before. I am using a completely up-to-date Windows 7.
