As a new user, I am am very insecure doing things that are second nature to most of you. I had AntiVir Version 6 on my computer. Have been prompted to upgrade and in doing so, I find that there are tons of bugs in the new version so I uninstalled that and went back to version 6. I have since been told that I must clean the registry of the old version 6 because it does not completely uninstall, then install the new version. Your product is recommended by AntiVir. It seems my problems always seem to be related to anti-virus programs. To make it worse, I'm a novice(at 63) and hardly understand the terminology. Is it possible for me to mess up the cleaning of the registry with your program? Will it require me to do things that are not obvious to a beginner? Your help will be appreciated.I have Spybot, Ad-Aware, SpywareBlaster plus the Microsoft anti-spyware program. Overkill? I don't know. I don't care what Antivirus program I use, just need one that is user friendly. Seems there is very little in the way of tutorials out there. I read your information, it seems clear enough...just checking. With thanks
