Update: I checked on YouTube, and unfortunately there are few reviews, and all are in foreign languages, but one I watched did the standard bad URL test. Surprisingly, some got through. I skimmed the video since it was long and in a foreign language, but 3 things got through. I don't know if it has to do with malware being signed, as I think SW checks for digital signatures, or if the malware was minor. SW doesn't seem to have the near 100% effectiveness of DW, Sandboxie, AG, etc. so unfortunately at this point I don't think I could recommend it. But maybe someone here could do a more recent test, focusing on the nasty stuff most likely to get through ie, Zeus, Blackhole, TDSS?
