Hi.I have many questions. 1)In my log there's always many blocked ICMP Type 3 Code 3 entries.When I look them up they are PC-Internet from my IP to my ISP's IP.Should I allow them? 2)I also get a lot of this thing: CRITICAL ERROR MESSAGE! - REGISTRY DAMAGED AND CORRUPTED FIX this problem Open Internet Explorer and type:registrycleanerxp(dot)com Once you load the web page, close this message window..After you installthe cleaner program you will not receive any more reminders or pop-ups like this...VISIT (the same url) IMMEDIATELY! I've looked it up and they are supossed to be pop up ads that are send to your pc.I don't get any pop ups but there are a lot of UDP entries in my log from different IP addresses,even spoofed internet addresses,that are sending this crap over and over.Even if LooknStop blocks this thing sometimes my connection gets slower or I get disconnected because of so many entries. Is there a way to make my pc invisible to these addresses or is it a problem with my ISP's network? Also is there a anti-spoof rule so you can see the real source addresses of these attacks.? 3)On the Internet filtering tab there are these two rules that do not have the green square thing:Block IP packets with MF flag set and Block fragmented IP packets.What are they? Should I keep them as they are?
