Hello! I appreciate if someone can answer these questions? Thanks in advance!
For the questions related to my computer, I have Spybot, Antivirus and Windows Update fully up to date.
1. After I fixed a friend's computer, we went to YouTube to show him that it was working properly. But I noticed that, as I played a video, an ad showed at the bottom of it, and it was covering part of the video. I had to click an X to dismiss it and see the video properly. It only happened on one video out of four. My question is whether this is normal, because I use YouTube fairly often and I've never had ads like this. Are they new? Or is there something I don't know? Spybot found nothing.
2. I run TCPView to keep an eye on the IP traffic. I hate it when the network lights go on and I haven't clicked on anything. Yesterday, I noticed some connections to some IP addresses that, when I try to run nslookup on them, it returns no FQDN: the message is "non-existent domain". I have 3 such IP addresses, how can I find more information about them?
3. When I run "cmd" as administrator, and run "netstat -a -b", I get a message for some connections that says: "Can't obtain ownership information". How can I find the process that hosts those connections?
4. Sometimes when I run TCPView, I see no activity at all, all connections are either UDP or listening, and yet, I see lots of network light activity. Is there any feedback regarding this?
5. Sometimes when I run Task Manager for all users, I see barely any activity at all (the System Idle "process" is something like 95% to 99%, and the System "process" barely ever shows up in the list (I sort by most CPU use)), and yet I see much hard disk activity. Is there any feedback regarding this?
6. When running TCPView, if I click on a button that says "Show Unconnected Endpoints (Ctrl+U)", then TCPView crashes. Is this a bug or perhaps something else?
7. I'm running on Vista, but I'm beginning to see friends with Windows 7. How can I enable network light activity animation on W7? Personally, I consider it a security issue that I can't see when there is network flow vs not. I have Vista's fake animation. I prefer the one on Windows 98 where the lights light up exactly at the moments there is any flow.
8. Sometime ago, someone showed me a Google feature where you would visit an URL like so: http://blahblahblah.google.com/blahblahblah/somewebsitename.com and Google would display security information regarding that web site. (So one would know if a website is spreading virus or not.) Does anyone remember when that URL was? I can't find it. :(
I'm very grateful for any and all replies. Thanks!
EDIT: Clarity of words.
