Avast partners?

I have recently noticed in my browser history, the sites liverail.com and pipewave.com. I am the only one who uses this computer and the day they are listed only Avast and IE accessed the internet. I personally dont use these sites and am not sure what they are.The only sites I accessed were Google and Youtube.

I know Avast has partnered for stuff like Google Chrome, so I am curious if this is a similar thing, or I may be dealing with a potential virus. I didnt post this in the virus section because I dont want to waste peoples time if it turns out to just be a partnership thing.

EDIT: Nevermind, I am now aware of the situation and no longer require help.

The thing to bear in mind is that all internet connections are run through Avast. Avast only connects to the Avast servers for updates. Hence those sites were accessed via IE
The partnership with chrome is purely the browser only


Neither is malware nor partners. A simple search of each one give these 2 results:

http://www.bing.com/search?q=pipewave.com&qs=n&form=QBLH&pq=pipewave.com&sc=0-0&sp=-1&sk=

They are sites that supply ads, probably from Google & YouTube sites.
