I will not enter into any debate, but want to share that the code leak of NT 4.0 and IE a few months back opened a security hole in IE versions less the 6.0 a mile wide. The breach is so bad that I just share about the leak and can't offer any fix to the issue.
What you may have been hit with could be the exploit, spyware or any number of parasites. This will continue with this version of browser.
Ejection of the parasite might be done with free tools such as Adaware, Spybot, Cwshredder, Stinger and Housecall.
In closing, its your choice how to close up this gap.
I'm running on IE 5.50 under Windows 2000 (office version). Somehow, my browser settings were changed to where I can no longer type in "www. " and access a webpage. I have to manually type "http://www. " before entering the address. I know there has to be a way (possibly through Internet Options) to change the settings to where it will automatically populate the http:// part after I type in www. but can't find it anywhere. Any ideas?
