I run AVG Antivirus (version 8.5, I believe). Now I want to install "Dragon Naturally Speaking", a speech recognition software. During installation I'm told that I need to temporarily disable my antivirus. How do I temporarily disable it?
As @Eroen already said, this might not be necessary.
Most programs install just fine with the antivirus enabled. If they don't, either the installer or the antivirus is poorly written.
Since you only disable it temporarily, there is no need to manually enable it afterwards. It will do so automatically.
