Malware is software that attacks your computer. It may come from a virus you download in email, a program you download from the Internet, or even from a couple lines of code embedded in somebody's website HTML.The purpose of malware may be to implant a virus into your system, steal stored personal information, like credit card or social security numbers and passwords to financial institutions, or even to hijack, or take over, your computer by remote.
Firewalls, virus scanners, and malware blockers are the most popular ways to protect your system from these types of malicious attacks. Google Chrome gives several new ways to protect yourself from computer attackers. With Google, search is king, and Google developers have used put their outstanding search technology to work protecting Chrome users. Google's spiders are constantly combing the 'net. These search bots collect information about every website they encounter and send the data back to Google. Each day, Google servers update Chrome's known malware and phishing site files. Much the same way your virus scanner updates with current virus information. When you attempt to surf to a site, or try and download a file, that's been marked as having malicious intent, Google Chrome will pop up a warning, so you can choose whether to take you chances and continue, or observe the warning and stop what you were doing.
In the event you surf to a malicious website that has not yet been identified by Google's spiders, you're still protected. Google Chrome uses something called sandboxing. This means that each tab or window you open uses its own memory, it's own resources, and is cut off from the rest of the computer. Almost as if tab or window has a spot dug out especially for it, on your computer. Like an old fashioned, child's sandbox. When you close the tab or window, the memory used is given back to main memory and the space occupied by the tab or window is filled in.
What this means in case of attack is the attacking code can't get out of the box. Computer code moves laterally, not vertically, so the virus, dialer, hijacker, or other malware runs into the walls surrounding the tab or window, and can't get out of the box.
Sandboxing and updated malware lists are not a replacement for solid firewall,virus and adblocker software, but they are terrific tools that add one more layer of security to your computer.
