Why can't I open google chrome?

[836]

So, I entered this page which was supposed to be certified and it said so on several official recomendations. From this site I downloaded a file but along with it came a virus or malware, I don't really know what it is. The only thing affected by it was Chrome. I scaned it with a million softwares and all of them said it had absolutely nothing wrong. So, I deleted Chrome and downloaded it again. When it finished downloading, I couldn't open it. I'm really worried because I do have a lot of information I'm very interesed in saved in my google accounts which are easier to view from Chrome.

How do I fix this? Thanks.
