Hi ened. I've had no problems with the Tesco.com website, although I use it mostly for the Tesco Finance side of their business. The Cool Web browser hijackings are fairly common and CoolWebShredder usually does a good job of sorting it. Unfortunately the auther of CWS has had to give up maintaining it due to other commitments. If you can give us more details of the problem we may be able to help you track down the cause.
