litecoin wallet strange registry settings

I've been using Bitcoins for a while now, and so I thought I'd give litecoins a try. So I downloaded the litecoin wallet from github but when I installed it and then ran it for the first time my firewall software warned me that it was trying to write to strange places in the registry, namely in the system registry for every component of sql server that I had installed like analysis services, and other suspicious locations like windows workflow and just about every other MS service on my system. Here's one example: (hklm\system\controlset001\services\bits) I blocked these registry entries from being set, but now I'm thinking Litecoin might not be worth the hassle to deal with. Can anyone shed any more light on this? Does the litecoin wallet software on github contain a virus? My antivirus software didn't complain, but something just didn't seem right to me.
