Hello,

In the last couple of days, I keep getting the following error message(see copy of the rror message below) on the internet/in the browser.
Have tried REFRESH and have reinstalled Java from since a buddy said something about a potential Javascript error...

Don't have a clue as to what this is and how to deal with it...

Any ideas? Fixes. guesses,similar problem?
Thanks

Hey Rich

Is this happening when trying to access all sites?

If this only happens on a few websites, give me an example of the links.

Hello,WheeDoggy and others:

Very perceptive question. Answer:

My impression is that it happens on and off everwhere on the web, from checking my Hotmail to other websites...
It doesn't always come on and don't see what the pattern might be...thought at one point very low RAM might trigger this but have experienced the message with normal(non-low) levels of RAM, methinks

Wish I could be more precise and informative...

One nutsoid idea: Recently installed BBC.co.uk news ticker and happened to read subsequently (spywareinfo newsletter?, I think) that Red Sheriff is some spyware that comes with bbc.co.uk install and I wonder if it could be some Red Sheriff-type spyware byproduct causing me this hassle...I'm probably going off the deep end here!!!

Alternatively, wonder if there's something in Tools/Internet Options/Advanced that should be checked off or unchecked...I'm flailing around because I don't have any familiarity with this...

thanks

Hello Richard

Two things spring to mind (that's good for me).

Security settings within IE, including COOKIE control (why does COOKIE sound OK whereas the English version BISCUIT sounds silly?)

Spyware/scumware! If you have SPYBOT installed, update it. There is a new option available called IMMUNIZATION or IMMUNISATION which appears to stop the auto download of these nasty registry infiltrators. Regards

Hello Crustyoldbloke, et al

Thanks.

Should've mentioned I'm using Spybot 1.2/Spywareblaster combo and have Immunization function active.
In Tools/Internet Options/Security/Custom, I have Cookies
ENABLE checked off and Cookies per Session ENABLE too...
That's all I know...

thanks

Try setting IE SECURITY and PRIVACY to DEFAULT values. Regards

Are you using a firewall? Perhaps tcp 443(https) or 21(ftp) not getting out?

Otherwise, I have to go with Phil in that you probably have the security up on high which is not allowing any scripting.

BTW, the RedSheriff thing is some spyware that I am hearing was installed with a Java update late last year (Q810030).
You can search for a file called javalog.txt that actually
logs when (if) the communication occurred if java logging has been enabled (can do this in IE settings - Advanced tab - tick "Java Logging Enabled".
The RedSheriff bother can be disabled using a firewall by blocking IP range:
203.166.18.0 - 203.166.18.255
Blocking it does not affect the functioning of Java.

Do you have a high-speed, broadband connection with a router? If so, who's the ISP and what's the make/model of the router?

I've seen that some ISP's have recently changed the permitted packet size that can be transmitted. Not all websites, but some do attempt to use an MTU size greater than 1500. If you have a router, you can change the setting manually to match what your ISP requires.

Before I go too far into depth, let's first see if you even have a router or broadband connection...

Here's a link that explains why some web sites experience this problem (I happen to support one that has recently discovered this problem with some of our customers):


On of the most common routers out there is the Linksys BEFSRxx model. Here are some screen shots & instructions to resolve it in that situation:


I should add that some ISP's used PPPoE in the past that didn't have this restricted 1492 MTU setting. For security reasons to help prevent attacks (and other reasons), many ISP's have made the change.

Since you didn't say you've change anything to any of your setting other than to install the news ticker, I'm going with the mostly recently install program theory, which is the news ticker. Uninstall it and see if it fixes your problem.

The problem you indicated is pretty general and it's completely within the possibility that spyware can and does causes your problem.

Just speculating here, but say the spyware sends your surfing habits to some database, but it's blocked by Spybot, before it returns control of your browser to you. Than it effectively blocks your access at random times for random sites with no pattern that you can determine just based on some counter they setup to randomly upload information about you.

HKinNYC...theory doesn't hold, as SpyBot doesn't block, but rather detects and cleans. It's not an app that runs in the background. But...good point. I'd totally overlooked the mention of the news ticker. Get this off your machine and run SpyBot ( to clean up any remnants. Does the behavior persist?

Footnote: (forgot to mention)

When I go to website--take for example--everything is normal. It's only when i click on links at site that error message appears up top...
don't know if this tidbit reveals anything...clicking on hyperlinks within web pages leads to hassle...original web site as such is fine...)
thanks
