If you read my first reply again, adverts can be poisoned and some major ad-servers have been compromised in the past.
So my advice is first and foremost block ads, in firefox I use AdBlockPlus I believe there is now an adblockplus for chrome, so I would try that.
As you can see the web shield and network shied are doing a good job, I don't know if you have made a typo on the domain name filetsee.com but I can find nothing on it, see image. I certainly wouldn't shoot the messenger so as to be able to browse. Try browsing the same sites using IE and see if avast's web shield alerts and you will see it isn't a case of it blocking chrome.
The web shield doesn't look for stuff, it intercepts http traffic so that it can be scanned. It isn't trying to stop chrome, it is blocking what it considers an infected site or infected element on that site.
How do you know you don't have an infection ?
