Hi DavidR,
That is off course also depending of what concessions you wanna make seen to your normal browsing habits and your other safehex measures taken (surfing with normal user rights will reduce the effects and payload of 92% of known Windows malware and general malcode to a large extentl, so what you as a user cannot do to your OS yourself the malcode cannot perform either).
It is a pity that a lot of pre-link browser scanners cannot be fully trusted now that trusted, reputable sites also have come under attack of grand scale CyberCrime mass website attacks (like beladen, gumblar, cruzer all sorts, etc. etc.), so reputation scanners have been turned into snake oil solutions now, and where real time scanners are concerned, you should run several to have some clue as what is safe to click (scandoo, finjan, xpl) and then you still can be taken by surprise.
NoScript still stands tall against existing and future malcode scripts, RequestPolicy is a great help against malcode re-directions, ad a last line of defense is formed by the avast shields. Keep your visors up, folks, you are under threat on the Internet,
