Hi there, Well my début on this forum went well, then - I've managed to fix it myself! It was the Haxdoor Trojan which had infected my PC. Symptoms included blank IE6 pages, my email kept closing and my Windows Firewall was disabled. The suspect file was mmx432.dll which Nod32 found in my Windows/system32 folder. finished cleaning it at about 4 o'clock Sunday morning. Anyone else infected with the Haxdoor Trojan, note it's only detectable with Haxfix. Have fun, y'all, and thanks for inundating me with replies.
