I've been trying out DrWeb SS for a while now on a couple different machines and so far I'm very impressed. The URL filter works very very and is accurate as far as I can tell. It seems to detect threats faster/earlier in the download process than many other products I've tried. Yes the on demand scan is horribly slow but if you know your machine is clean then then this is irrelevant anyway since there is effective on-access protection. Too bad they won't let a credible and respected third party testing organization give exposure to their quality product. However, i have a question hopefully some one here more experienced with Dr. Web can answer: Why does Dr Web run 2 instances of dwengine.exe with only one using any resources? I've looked and found some outdated information regarding this issue but have not been pleased with the info I've found. Can anyone answer this question or share any relevant info/experiences regarding this product?
