internet will not load a website and the memory is being hogged by "CCPROXY.EXE"

After being online for awhile, the screen pops up that it can not load the page or find the internet. I can PING a site but not open a page on the internet. At the bootom it says something about "c:winnt/system32/shdoclc.dll/dnserror.htm". Even after unpluging the NIC and closing the internet windows it still will not find the internet. I have to reboot for it to open a site. It does this evertime I am online for awhile.

Also the the memory is getting hogged up by "CCPROXY.EXE" and "IEXPLORERE.EXE" Sometimes they both will use up all the memory and nothing will run, it just locks up everything. Aand then will not load the page or site.

I recently installed a new USB wireless NIC. But the problem was there before I install the new card. The computer has all its updates.
I run windows 2000 and have Norton internet security.
I have posted on your malware forum. They found nothing on my computer. Do you know of anything that will help

 

just wondering if anyone could help me out with my problem.
