Dude, I am running into the same thing. I am on Windows 7, 64-bit, using IE 8 and Avast 6.0.1367, and have Google as my homepage as well. It happens intermittently and started maybe 2-3 weeks ago. I'm tempted to just use System Restore to take me back a month. So far Malwarebytes, Avast and Spybot Search and Destroy has all found nothing. I will let you know what else I find out. Oddly enough, I find barely anything about this symptom on Google, except 2 othe people besides us asking about it. The common thing? Everyone affected is using Avast, IE and have Google as their home page.
I have noticed that since it started 2-3 weeks ago, I wonder if IE just craps out when trying to display the new Google olympic pictures/links. Maybe I'll try changing my homepage to Yahoo or something for a week or two.
I sure hope my computer didn't get infected with the super virus that Iran was targetted with LOL. If all else fails, it's back to the good o' reformat/reinstall of Windows.
BTW, did I tell you all how friggen fast 2 SATA 6.0 Gb/sec SSD drives in RAID 0 are? Smoking fast. Windows boots up in less than 10 seconds, Word 2010 and Photoshop opens up in a sec, and virus/maleware scanning of my computer fishes in a fraction of the time it used to take with SATA 3.0 Gb/sec 7200 RPM drives LOL. And yes, I know TRIM doesn't work when using RAID 0 with SSDs, but the new garbage collectors in newer SSDs work much better, I hear anyways. If you're going to spend $100 on something else for your computer, use it instead to buy an SSD to be your primary OS/application install drive.<br /><br />-- 11 Aug 2012, 03:42 --<br /><br />Alright man, try this. I finally took the time to do some investigative work as I am a computer guru, and I found that the some.url is IE's way of saying it can't find the website (whatever that website is). Anyways, I'm not sure if your real homepage is triggering it or not, but specifically, when I looked at some of the sources and other places in the background, I found that this error is related to Windows not being able to find name resolution (DNS). As a result, I did a DNS flush, and so far, I have not experienced it. However, only time will tell within the next week.
To apply this potential fix, try this (if on Windows XP). Even if this is not the real solution, it will NOT harm your system in any way.
1) Go to your Start menu > Run and type: cmd
2) Press [Enter]
3) In the Command Prompt window (or that black window), type: ipconfig /flushdns
4) Press [Enter]
5) You should receive a message that says "Successfully flushed the DNS Resolver Cache."
6) Let us know after a week if the issue comes back.
For Vista/Windows 7, on step 1, go to the Windows circle icon on the bottom left > "Search programs and files" and then type: cmd
