I am using IE8 on Windows XP Professional on a Dell Precision T5400 64-bit platform PC.

Everything has been running fine for the last year and just the other day, Internet Explorer started behaving odd after I installed Spybot Search and Destroy and cleaned up some temporary internet files, cookies, and temp files.

Here is what started happening. The remember me checkboxes that can store your username and password like on the like on this site no longer are persisted. Everytime I close the browser and come back to sites that I had saved my username and password, I have to login again. It is like my cookies aren't getting stored. I've tried dumping the temporary internet files and cookies, but the problem still occurs.

Also, flash video used to run fine on IE, but now it doesn't. However, I've dumped the temporary internet files and rebooted and flash videos would run okay for a day or so and then the same problem would occur again...can't view Flash videos.

Finally, I use outlook webmail to access my company email from home and when I get file attachments, sometimes I can't download the files. I get an error message saying "Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later."

There isn't anything wrong with the site or file I'm trying to access and as I indicated, I hve been able to reboot and then download the file.

It seems like some IE settings are either got messed up or something has been corrupted.

I can use Firefox no problem, but I did notice in Firefox that my username and passwords are not getting persisted as well.

I can't if there was a setting in SpyBot Search and Destroy that did something or if something else is going on.

I'm trying to trace down the cause and get this fixed.

Any help would be appreciated.
Thank you.
