It looks like McAfee internet security software has a nice surprise for its unwitting users. Some are finding that their email addresses have been blocked when using the RumorServer Service myAgtSvc.exe, McAfee Peer Distribution Service, which is part of McAfee SaaS Endpoint Protection Suite, previously known as Total Protection Service. c|net reports that the software allows computers to serve as open spam proxies, because the service has been hacked. The Kamaar blog first detected this problem on Jan 4th and reported on it, also giving a workaround to affected customers until McAfee fixes the problem. This problem is somewhat ironic, because the customer would actually be better off without McAfee's help, so it can't be good for the company's reputation. It's also taking them a rather long time fix a serious flaw, which doesn't build confidence in their products.
