I have Windows XP SP3 together with the latest IE8 installed on my PC and Netbook and both are running Avast Pro 5 and paid for Malwarebytes'. On the Netbook there is no problem downloading the uploader for the web sites of Picasa and Facebook and all works ok. However on the PC I get an error message which prevents me dowloading Active X for the uploader for both web sites. Strangely I have no problems with Youtube. Does anyone have any thoughts as to a solution for this problem bearing in mind that the PC & Netbook have identical browser settings etc.
