System is as follows:
Microsoft Windows XP
Service Pack 3
Dell DIMENSION DIM2350
Intel Pentium 4 CPU 1.80GHz
1.79GHz 1.00 GB RAM
Windows Update no longer works from Start Menu or manually from Microsoft's website. From the start menu, when selecting Windows Update, it opens IE window but IE reports that "Internet Explorer cannot display the webpage" and has the "Diaognose Connection Problems" box. Typing the url to Mircosoft.com connects fine. Once on the Windows Update page it starts Checking to see if the computer has the latest version and then stops and reoports "X The website has encountered a problem and cannot display the page you are trying to view."
Connecting to internet using the Desktop IE icon works and navigates to other sites ok too but often getting a Windows box stating "Generic Host Process for Win 32 Service has encountered a problem and needs to close. Do you want to report this to Microsoft..etc." I have selected to report it many times and then IE will usually shut down. Typing a search phrase in the IE search box returns Google results to the page but when selecting any of the search results it ends in a redirect to some unrelated page. This does not happen if you type the url for Google in the address box and then do the search. All of these things happening seems to be some kind of virus infection that keeps coming back from somewhere in the software.
I am using AVG Free Edition 2011 antivirus. I have run the scans quite often and keep it running in the background. AVG still updates the database everyday. It has removed an identity theft threat a couple of times after doing its scans. It is also catching attempts and I move them to the vault. It has also detected Worm & Trojan Horse threats in the past ok and removed them. I also use MalwareBytes' Anti Malware program and it removed 4 threats.
The computer no longer seems to update automatically using Windows Update like it used to do. I am not sure how long that has not taken place. It has been a while since I have see the Update shield in the Sys Tray telling me that I had updates ready to install. I have a feeling that this may have started with the Windows SP3 but I don't know that to be a fact. I can only assume that I have some type of infection that can't be detected with the tools that I am using. Any thoughts, advice, and help is much apprecited.
