I had the same problem with AVG. So, I went - twice! - to the program and set the exclusion for those two .dll files and re-started the computer both times. Ran okay yesterday. Today, I turn on the computer and the AVG program not only says that the GC Gold .dll file is a virus but removes it from the file and puts it in their "Virus Vault". Okay, I think, how hard can this be and go to the Vault to 'Restore' the file to the program folder. Not allowed; get an error message that says to us 'Restore as'. So I do that and get the same error message. Thinking I've made an error, I redo the entire process and get the same results. Went to the AVG site and got a PIN # for a support phone call. See, if I turn off the computer and wait too long the AVG program will delete the file. Nice. So I call support and a very nice-sounding man tells me that I will be getting an email from him with instructions on how to correctl do the exception but that I'll have to re-install GC programs. Not happy, but okay. That was four hours ago and no email. So, I un-installed AVG and got a different program and installed it, avast, if it makes a difference. Free copy with similar limitations to AVG. Read the instructions carefully and put the entire Battleground folder off limits to the anti-virus program. We'll see. My advice? Ditch AVG, get a different anti-virus program and - sigh! - uninstall GCG and GC and re-install them. Don't forget you have to unlicense and relicense, but that's easy and the program (GC) reminds you. Some fun, huh?
