Hello Juan,For starters I would clear your cache and cookies. Next follow the troubleshooting steps in this article very carefully."If you notice Chrome behaving strangely (for example, causing crashes, unusual startup pages or toolbars, unexpected ads you can't get rid of, or otherwise changing your browsing experience), it may be due to an unwanted program on your computer. Youmay be able to fix the problem by downloading and running the Chrome Cleanup Tool. Think of this as a “factory reset” of Chrome. It restores Chrome's original settings and removes programs that affect its behavior.
