Google chrome wont install...?

[Huh?]

I got a virus on fire fox and chrome, did a full scan and it didnt infect my computer just those two browsers, they had a fake search engine, no google and would only bring up fake websites...usually asking for card details, I restarted fire fox and it fixed it but had to uninstall chrome now it wont install again, I did the whole process explorer and ended all activity that had chrome or google, still wont install, really need chrome back! does anyone know how i can install it again?
