In the ADD-ONS, a XUL Cache reinstalls itself even though I uninstalled on the last session. According to Google search there is some sort of a virus file that attaches itself to the XUL.DLL. The file has two names, one is called XUL.mfl. My McAfee and System Mechanic does not even recognize it. I deleted this file according to the instructions I found but to no avail. This problem continues to exsist. The other file name is XUL.mfast which I did not find on my system. What this has done is... my home page is frontiernet. they post several news stories on their front page. If I mouse over to another story other than the first top story, the picture will not change and when I Google search for something and then click on a link, I get redirected to another link which will not let me back out and go back to my search page. Every link gets redirected to the same "bad" link but site adviser never detects the threat. ????? Please help! Thank You!!!
