Running windows Vista Home. Bit Defender advised I had a trojan, but could not get rid of or delete. Installed AVG Free and now my computer has no sound and to boxes come up with restarting the computer "application failed hccutils.DLL not found" and "unable to locate igfxtray.exe." Still no sound . Please help. I can not play videos, sounds or view photos. Every time message states; "Run DLL"
