I have used MS Antispyware and been quite happy with it ever since it came out. Reviews of it online have been pretty decent. Someone at a security forum has recently recommended I use Spyware Guard. I wasn't too thrilled with the fact that it doesn't do a manual entire-system scan, but I can find other apps to do this. I was wondering--would there be any reason to switch from MS Antispyware to Spyware Guard? Is its scanning/detection technique that much better? Does it do more things? I didn't find this topic in a search, although I found some pretty interesting threads in this forum. Specifically, I see in the program control panel that it monitors .exe and cab files, blocks BHOs, as well as spyware onto IE, which as Firefox user I rarely use anyways. I believe MS AS does quite a bit more. Not trying to start a flame war, just wondering--are these two programs in teh same group, or do they try to do different things? Thanks in advance.
