Help. We are on BT home hub with several PCs in the house working fine. My sons PC will not let him get onto the internet ( or it will if I play about abit). The bar on botton right says hes connected but when he tries to log on it says IbisCont.exe has stopped working and /or internet explorer has stopped working. Some other bits and pieces also freeze and say they are not responding etc. I have been told that there is a Ibis tool bar which can cause issues. Any suggestions for a PC novice. FYI BT hom hub 2, AMD Athlon LE-1660 processor.
