The challenge to go online safely becomes greater.

We have faced with virus, adware, spyware etc. for some years. Most of us would take care to look for any sign of danger, yet, the bad guys are using all means to get their jobs done.

"Malware Hides Behind Legitimate Companies" stated the latest situation that many of us might not be aware of.

The same problem happened to me recently. After visiting an official site in China and searching for something, my computer was infected with a new and powerful virus that was not able to clear with anti-virus tool. With numerous trials failed, I have to install the Windows again.

A simple truth today is that all computer users must get prepared to re-install Windows because no matter how careful we are, there is always a chance to be hurt by new virus etc. Each time, they are more powerful and it is certain that they know what protection we have.
