10 Signs And Symptoms Of Spyware and Adware Infections

Your system runs noticeably slower than it did before. It could be infected by spyware and adware.

A search toolbar or other browser toolbar appears even though you didn't request or install it. Spyware and adware programs are usually installed with other programs that are advertised in legitimate ways.

You receive an email in your email client with offers related to your recent Internet searches. A spyware or adware program might be monitoring your buying habits.

You enter a search term in Internet Explorer's address bar and press Enter to start the search.
Instead of your usual search site, an unfamiliar site handles the search. A spyware or adware program might be responsible for this.

You get pop-up advertisements when your browser is not running or when your system is not even connected to the Internet, or you get pop-up ads that address you by name. A spyware or adware program could be doing this.

When you start your browser, the home page has changed to something undesirable, normally to a search portal that the spyware or adware program is trying to market.

At a time when you're not doing anything online, the send or receive lights on your dial-up or broadband modem blink just as wildly as when you're downloading a file or surfing the Web. Or the network/modem icon in your system tray flashes rapidly even when you're not using the connection. This could be a spyware or adware program sending out info from your computer.

A new item appears in your Favorites list without your putting it there. No matter how many times you delete it, the item always reappears later. Spyware and adware behaviors are normally very annoying.

Your spyware or adware cure program stops working correctly. It may warn you that certain necessary support files are missing, but if you restore the files they go missing again. It may appear to launch normally and then spontaneously shut down or it may simply crash whenever you try to run it. Some Spyware programs will try to shut down your computer security programs so that they can run without being noticed.

Everything appears to be normal. The most devious spyware doesn't leave traces you'd notice! They are sitting in your system, malignant and undetected but their destruction is happening.
