Recently, I was testing out Norman Malware Cleaner ("NMC"), and within a short time, and I've come to a conclusion. In my opinion ("NMC") rates a -10, on a scale of 1 to 10. Why? While testing it (quick scan), without permission it altered several of my registry entries, without asking permission, and this is when allowed it to run only about 20 seconds or so.
After further investigation, I determined:
1. It by default, the program says to clean things. This is wrong! The default should be to ask of something is to be removed. If the individual user wants it to be removed automatically, the program should make the user go into a configuration area, and change it, or at the minimum, ask permission to make the change(s). This is poor programming.
2. The program changed my windows firewall settings. I have windows firewall turned off, because I use COMODO Firewall. This program should not have turned windows firewall on, and COMODO Firewall off.
3. The program modified and entry to have COMODO Firewall start automatically.
The entries in #1 were easily changed back, but shouldn't have been changed in the first place, without permission. As for #2 and #3, that could have caused me great difficulty. Since I have a pristine copy of windows (because I use Norton ghost), I restored by computer using ghost, and then restored my files. Total time, about 2 hours, most of which was restoring the files I previously zipped.
With 10 years in IT I know that Norman should have, as said above, made the user to change configuration items, or AT THE MINIMUM, requested permission to make the changes. This software is a piece of garbage in my book, because of the above.
