Make sure that Windows is up to date, especially Internet Explorer (IE8 for XP and IE9 for Vista/Win 7) and its add-ons (Flash, Shockwave, Java etc. etc.) and go into SecurityCenter and make sure the browser has full access.
Double-click the icon to open SC.
Click Web and Email Protection
Click Internet Connections for Programs
Click the word Program at the top to arrange them alphabetically
Locate IE and make sure its got Full access using thr Edit button if necessary.
If that doesn't help I recommend you contact Technical Support by phone or online chat, it's free and linked under Useful Links at the top of this page.
First of all, thank you for your respond.
Allowing all connections of IE is not a viable option. Sometimes I or my family members may run into some malicious websites unconsciously. And the firewall provides a very good protection upon such events.
Besides, I don't think IE is responsible for everything, otherwise shouldn't closing IE terminate the problem? If this is wrong, please point it out for me.
It's your choice. You could perhaps try another browser like Firefox for instance. Otherwise your best advice is to consult with Technical Support as they may be able to poinht out a setting that needs tweaking perahps.
So here is not Technical Support? Could you give me some links?
