My mom bought my son a new alienware computer. Very big.  Very nice (much nicer than mine, except he gets my old monitor and I revel in 24" glory).  It came with mcafee installed on it.  I am not familiar with mcafee.  I use symantec, and I've never had to think about it much past keeping it on and it very occasionally catches something.

My son's computer seems great, and I've made it homey by adding firefox and google desktop and various addons and open office and all that.  It surfs everywhere I want to go, except videosift.  At first I thought it might be the adblocker on firefox, but I can't get there on plain old internet explorer either.  So I figure it has to be mcafee, so I disabled the firewall (figuring I could figure out if it was mcafee and figure out what to do correctly later: I still can't get to videosift.  Even worse, after I try to get to videosift, it's like my network is frozen until I reboot my computer.

Does this sound familiar to anyone?  I don't want him to be unable to go to videosift (I send him links to vids pretty much daily).  Any suggestions?
