Apparently also removes/scans together, so you can’t even say No to removing something it has found. That is always bad imo, with reg. cleaners
From what I read there and elsewhere, it will repair the first 15 errors it finds, then tell you to pay for it to clean anymore.
You can get better for free, elsewhere, like Ccleaner>>http://www.piriform.com/ccleaner
Always back-up any changes to registry before proceeding.
My advice is Registry Booster doesn’t play very with other software on your PC and I would remove that software dead out the door, I prefer a user friendly software that doesn’t do deep scan Registry because deep scan and really damage your PC and it may fall into a nasty trap of reformatting your HD believe I’ve been there six times it not very happy place.
Ccleaner is a very friendly software and it doesn’t damage your PC it doesn’t do deep scan registry, there are a lot of people who have been experiencing major problems with Registry Booster just because it has a Microsoft Gold Certified partner doesn’t mean is the best and most trusted software.
I say get rid of Registry Booster it far to dangerous and it doesn’t play very well with other software, it would be better if you listening to us because we’ve been there and done that before with other software “The Good”, “The BAD” and “The UGLY” dark-side of the software.
There are a lot of great people in here who has many experience in many different ways on the Good, Bad and Ugly dark-side of the software.
Before you install Avast make sure you run the CCleaner to clean out left over register first make sure you do a register backup before you start cleaning and then reboot and than install Avast, would someone please advised krypton what else he/she do to do before installing Avast is their anything else.
