I have posted in the KAV forum here and a member mentioned that Prevx had a forum here as well. I am doing a new install from a CD of KAV 2009 and I can't get it installed as it is asking that I uninstall Prevx Edge? I don't want to do that as I am not sure how to reinstall it even though I have my key number, I get concerned about going to the site where it suggests that I purchase it after download and if I have a key that I could extend the time on my app. I don't want to extend the life on my app and I really don't want to uninstall the program as my brother did not have to when he did his KAV 2009 install sometime ago. Is there a reason that these 2 apps don't complement one another at install and will there be issues after...if I ever get the KAV 2009 installed? I previously used the KAV version 7 but it ended its life Jan 10, 2010 and so I decided to attempt to install the new version and used the KAV tool cleaner and then loaded my KAV 2009 licenced CD in and didn't get far. I would appreciate comments, thank you. BTW, I have always been pleased with the interaction of KAV version 7 and Prevx Edge.... and now this.
