I reported this as a bug a while ago and a bit disappointed that it hasn't been addressed in ewido 4.0 final. Starting Offline Explorer Pro takes a lot longer with ewido guard enabled. For example, it takes about 25 seconds with the guard enabled, and 7 seconds with it disabled. To reproduce, just download the latest version of OE Pro from http://www.metaproducts.com/mp/mpProducts_Detail.asp?id=2 and install it. Then, time how long it takes to startup with the guard enabled and with it disabled. Even if the problem cannot be fixed with ewido, I would appreciate if you could let me know what guard.exe is doing during the startup of OE Pro, in case there is something the author of OE Pro can do to help fix the problem.
