You can just ignore it.  I can assure you that the file is safe.  Virus detectors will often say that things are "malicious" or a "threat" from MsgPlus (or associated sites) because of the optional ad-ware in the MsgPlus unstaller (and realistically it isn't that bad, Patchou has made sure it doesn't do any damage).  Just don't stress about it and use the ignore button and everything should be alright.

Thanks for reporting this to us though, we may get in contact with AVG and recommend they look into the reasoning behind this and try to fix it.
