Possible solution
You may have spyware on your computer. Spyware is software that usually
runs silently in the background on your computer, collecting and sending
information about you and your use of the computer to another person or
system on the Internet.
You can find and remove spyware from your computer by using any one of a
number of software programs available for this purpose, including Windows
Defender.
To scan for spyware using Windows Defender:
1 Click the Windows Start Button, All Programs, then click
Windows Defender.
2 Click Scan.
Many of the popular virus protection programs also have some tools that scan
for and remove spyware from your computer.
To avoid getting spyware on your computer:
Do not install programs if you are not sure they come from reputable
companies. Check the company's Web site carefully for information about
what is included with the program.
Do not automatically click Yes when a download window asks if it is OK
to install a program on your computer. Read the message in the window
and make sure it is a software program that you really want.
This is typically caused by adware or advertising-supported software.
You can configure your Web browser to block pop-ups (available in Internet
Explorer by clicking Tools and then Pop-up Blocker).
To remove adware from your computer, use the antispyware/adware program
included on your computer (select models only) or any number of available
software programs that remove adware programs.
Note that many of the popular antivirus programs have tools that scan for and
remove adware from your computer.
