3.0 causes 'DNS address could not be found' problem

[F01300]

Since accepting the 3.0 update prompt, a lot of websites I have had no problem visiting in the past have become inaccessible (server  or DNS address could not be found).

Some of these sites had been excluded (web exclusions) in the previous version (mbam 2.2.1.1043) and although the exclusions are still listed in V3.0, the sites are accessible only if I turn Real-Time Protection OFF.

The problem exists on all the browsers and disappears as soon as Real Time Protection is turned OFF.

This has become such an impediment that I have now removed V3.0 and re-installed mbam 2.2.1.1043.
