After disabling protection and exiting as instructed, I removed SpywareBlaster4.3 using the native uninstall program. The original installation and setup was monitored using Revo Pro. Running Custom Uninstall from Revo shows a frightening number of logged entries remaining in the HKEY_LOCAL_MACHINE System and HKEY_USERS hives. Not all are easily identified with SpywareBlaster, but a huge, recognizable number of items are still present under the following keys, among others: HKLM\Software\Microsoft\Windows\CurrentVersion\Internet Settings\P3P\History; HKLM\Software\Classes\(CLSID|Interface|SpywareBlaster); and HKU\S-1-5-...\Software\Microsoft\Windows\CurrentVersion\Explorer\ Internet Settings\(P3P\History|ZoneMap\Domains). I have not installed the current version 4.0. Is there a utility or .reg file available to perform a more thorough removal of the earlier version and its data before doing so? Or will the updated version reclaim the orphaned data and settings entries? Thanks.
