Hello,
After installing some windows updates I receive from time to time in Vista as well in XP XP3 an error popup when I access a WWW site.
Some times the F5 solves the problem , other times no.....
The attached screenshot is an example of the popup
Any idea?
Thanks in advance.

Are these secure sites or sites that you have to enter a login and password? Have you deleted all of your temp. files, cookies, and history?

Hello,
These are mostly non secure sites where I have to input a userid and password.
I will delete all the cookies ...
Thanks for the help and I will come back later

Hi,
All cookies and passwords deleted but still the same error popup.

Did you delete the temporary files too?

I am having the same problem. I have cleaned all temporary files, cache, reset IE.

A while ago someone told me to find all the Yahoo apps that might be running that I am unaware of. I forgot how to find them I typed something into the search box and then opened other windows-but I do not remember what I did. After that everything worked great for about 1 week-perhaps some yahoo things came back? but don't know how to check.

Hello,
Yes I made a delete ALL
Thanks for your help

It could be malware hidering you from visting sites. Try a HJT log and see if it comes up dirty.
