Adware is computer software that displays advertisements on your PC. These are the ads that pop up on your display screen, even if you’re not browsing the Internet. (Some companies provide “free” software in exchange for advertising on your display and this is how they make their money).
Spyware is software that sends your personal information to a third party without your permission or knowledge. This can include information about the website’s you visit or something more sensitive such as your user name and password. Unprincipled companies often use this personal information to send you unsolicited targeted advertisements.
Some forms of spyware are even worse and can act almost like viruses, hijacking your web browser, popping up ads, or just generally wreaking havoc with your PC by slowing things down or preventing Windows from reading your hard drive!
Adware and Spyware are a modern scourge and any web search will reveal how widespread this problem really is.

At QBS PC Help we recommend several free software tools that can help to combat Adware and Spyware and these include; AdAware, SpyBot Search & Destroy, Malwarebytes and Microsoft Windows Defender (already installed in Windows Vista and Windows 7).
For checking spyware, adware and rootkits Prevx CSI is a fairly new security tool that we are currently using and it works well! And for clearing the Windows Registry, temporary files, browser or start menu run histories and cookies we love the highly rated CCleaner.
