I read for that SiteSucker utility that, "It does this by copying the site's HTML documents, images, backgrounds, movies, and other files to your local hard drive"
Those 'other files' could be the vulnerable ones. But as long as you virus scan the downloaded files before opening them, that should be OK.
Two things though;
You would need an open and active internet connection for these utilities to work, so I am not convinced making the browser offline would help protect you.
On the other hand, you are using a Mac. There are malware threats for the Mac, but they are so few that I suspect the risk is vanishingly small.
Other Mac users here may see your post her and offer to comment, but just in case, I've asked Pete, (mrmacfixit), the Moderator for CNET's Mac forums to confirm or otherwise.
Hi, I am wondering if using an offline browser such as SiteSucker http://download.cnet.com/SiteSucker/3000-2377_4-10056980.html?tag=mncol
would remove the risk of getting a virus? SiteSucker "[copies] the site's HTML documents, images, backgrounds, movies, and other files to your local hard drive"
And SiteCapture apparently takes a screenshot of the website.
My guesstimation is that the answer is "no" because since SiteSucker brings all the files to your hard drive, you would get the virus included in the files. But I'm not so sure about SiteCapture though, since all it does is take a picture of the website.
But yea, despite my guess, I want some kind of affirmation or opinions or whatever. Just to be sure
