If you use Google for searches, be cautious typing Google's URL. CNet warns that there's a trap if you mistype:
Security researchers have discovered an attack aimed at would-be visitors to Google.com, one that attempts to download malicious programs onto the computers of people who simply mistype the search giant's Web address.
According to security specialist F-Secure, unsuspecting Web surfers may be bombarded with various types of Trojan horse threats, spyware and backdoors when they go to "Googkle.com." The scheme is meant to take advantage of sloppy or hurried typists, given that on most keyboards the letter "k" key sits next to the "l" needed to type "Google."
A safer way to use Google is to download their toolbar and conduct your searches from your browser.
