Chrome redirected to COMODO

Hi.

I use the latest Chrome on a win 8.1 laptop.

It seems that about 10% of time when I click on links from various sites, I get the following message.

The URL "null" is not valid. Did you mean www.nolo.com?
(the page says COMODO from http://nxd.securedns.dns.com/ ...)

Then always, when I click the browser back-arrow and try it again, it works properly.

This is very annoying.

Long ago I deleted any alternative search engines from my settings.  Google is still the only one.

Any solutions?

Thanks,  
WS

Something to try... Adwcleaner is great for cleaning out browser hijacks etc.

This link
 http://general-changelog-team.fr/en/downloads/finish/20-outils-de-xplode/2-adwcleaner  

is a direct download link for the program. Put it on your desktop. It is a free standing program and requires no installation. The icon is a blue bug. Double click it to run, click Scan and allow it to finish scanning. Then click Clean and the program will do its thing and you will have to reboot. After reboot the program will produce a .txt file listing any stuff it has removed.
Worth a shot.

Check to see if you have a proxy set...
If so, turn it off!

You can find this under CONTROL PANEL==> INTERNET OPTIONS==> LAN SETTINGS

Proxy is/was not set.  It was off.

The Lan Settings I found was under Connections.

If I looked in the wrong place then please let me know.

Another possibility is a funky DNS server (possibly set by ISP)...
Try overriding to some good public DNS servers.

No idea what that means or how to do that.  My laptop is directly connected to cable internet through a router.  My frequently used iPhone and iPad both connect through that router's WiFi with no problem.

I don't know how to solve this annoying problem.  It started about a week ago.  I frequently run Avast, Malwarebytes and Hitman Pro, which show no problems other than cookies.  The computer has been shutdown a couple times recently too.

davidlevans13,

I see the product has mixed reviews.  

Is that your personal experience with it?  
Have you run in on a Win 7/8 with no problems?

Thanks

I have used it with great success on Win 7 and XP. Never tried it on Win 8

I solved the problem myself.  It turns out that about a week or two ago, I elected not to have HitmanPro delete my FLV (Flash Video) Plaver stuff, thinking that I needed it.  I ran HitmanPro again and deleted that stuff, and after two days, have not had the COMODO problems at all.


Nevertheless, I've awarded this question, at full value.


davidlevans13,

Interesting product.  I ran it and it "found" a lot of things  -- many of which I don't think I'd want to tamper with.  It also produces a log.txt file that I can easily reproduce for other future problems.  

Too many things to uncheck before cleaning.

Do you know if the product "Clean" function cleans all the checked items in all the Tabs at once, or if it just cleans one selected Tab at a time?

I believe it just cleans everything that you don't uncheck.

I have never found anything it wanted to remove that was worth keeping, so I just let it clean.
I was initially concerned about the registry entries and things, but they were all associated with things I didn't want on my machine.

Glad to hear you sorted it out yourself, and got things working well.

Thank you for the points.
