Who in this world likes to download a trojan instead of the program you want to get?
In my case, when I tried to download Google Chrome, avast saved me from downloading a trojan called Win32:Midgare-OI [Trj] and it seems that I am not the only one who has run into it
I thought that I was being saved by avast but after reading the mentioned post in google groups, I have found that it might most likely be a false positive by avast. I do not think that Google is going to be happy with the impression given to many users that were using avast and tried to download chrome.
Here is the screenshots if you are interested.
Image 1: You can see that I did not even have time to "save" the file to the hard drive.
Image 2: I tried to download Google Chrome with Internet Explorer and get asked if I want to "run" the program. If I cancel and go to next page to download the file, I get the same trojan warning
