I don't have an answer to your main question, except that I suspect you will be able to download Windows Defender again. I am sure that Microsoft would accept that some systems have to be re-installed, etc, meaning they lose Windows Defender.
But I am concerned about the rule you created in Kerio. Unless you can delete it, would it not remain in force even if you uninstall and reinstall Windows Defender?
Unless someone else here has any views, could you ask this question in the V&A forum, and/or see if Kerio has a customer's forum itself?
My system configuration:
Compac PresarioProcessor - 2.40 gigahertz AMD Athlon64Memory - 512 MB200 GB hard drive
My operating system:
Windows XP w/SP2
I have Windows Defender installed and it has been going great for me ---- except I made a mistake.
The other day, my Kerio firewall popped up a dialogue box saying that a file with the name of mpas- (can't remember the letters).exe.
I did a Arin Who is search in their data base and it did not show up. So, I denied it and created a rule. I evidently should not have done that. Since doing that, my Windows Defender will not do the daily automatic scan that it has been doing since I installed. I have to manually scan.
I've been unable to find the rule creating area in my Kerio program. I've emailed Kerio twice and they have not responded. So much for free tech support!
Anyway, my question is, if I uninstall the Windows Defender and go to Microsoft and get it again, will I be able to download once again and continue as it used to be? Since I had to register it the first time, I didn't know if they would let me get another one.
Thanks for any help.
