I had a client on their Windows XP PC open the infamous Fedex email virus. I was able to clean the computer as far as I can see and get it running again with one issue. They cannot get into Google using any browser on that computer.
There are 3 others computers on their network and the others can get onto Google fine, but for some reason this computer will not open Google.
I ran malwarebytes and Superantipyware on the computer, they found 6 and 73 suspects respectively and they were removed.
If I uninstall the network card then re-boot the IC is installed again automatically and I can get onto Google for a little while then if I close and open again a browser it stops.
