I recently purchased NOD32 and plan on getting TDS in a few weeks. I was just curious about Worm Guard. Do I really need this kind of protection if I'm aware of double file extensions, hidden file name issues, and if I really don't open any attachments unless they are from friends (and even then I would be scanning them with Nod32/TDS). What advantages am I missing if I only had Nod32/TDS? Lastly, I was just browsing other threads and saw a mention of webpages being able to cause some damage. What methods are used for this and how far can it go? No worse than changing your homepage by answering yes? Which reminds me, adaware found some files in the temporary internet files folder (.js files). Are these an example of harmful ones? Another concern of mine from WG.. It sounds as if it checks any file that is touched. I prefer just right clicking on anything I'm concerned about and scanning it that way. Would this be another reason I can save some money and go without WG? Thanks in advance for your input.
