Hi, I just tried the three test files at the bottom of this page from AV Test.org. http://www.av-test.org/sites/tests.php3?lang=de#short (2002-11-04) What was strange was that Wormguard blocked my attempt to open each of these files. I thought TDS-3 would have been the one. Now here is where it got really odd. I closed Wormgaurd to see what TDS-3 would do and again WG jumped up and blocked each attempt. I tried reviewing my task manager but did not find an open process that looked WG and I did the whole thing over it appeared that I had successfully closed WG but again it was there doing the block. Not that I am complaining but is it normal for WG to working this way and if so, was intended to be opened, click on install, and then closed as an active app but still be active in the OS (i.e. no window/systray, etc)?
