Follow these steps which has a 95% success rate of removing spyware and adware.
Your first line of defense is a good Anti Virus software.
Most Antivirus programs are commonly available in two forms.
The first form is Antivirus and the second is Internet Security.
The Internet security version replaces the Windows Firewall with their firewall.
I personally just use the Antivirus form as I see no advantage to having some additional firewall.
For Anti Virus I recommend either Kaspersky or McAfee.
If you have either make sure they are updated.
There are two types of infections that most PC users wind up getting.
One is Spyware / Malware and the other is Adware.
The difference is Adware just adds popup and other ads to your browser making browsing the web a bit of a nightmare.
The others cause your PC harm by various methods. Some claim to be Antivirus programs which is telling you your PC is infected.
Also it tells you if you send them X number of dollars it will remove the infections.
Of course it is a scam and hope if it happened to you that you didn't fall for it?
Even the best Antivirus applications can't block everything out there.
If you are not careful and take your PC where no man has gone before you are bound to find some bad boys.
To fix your problems should you have fallen victim to one or more of these unwanted infections follow these two steps.
After you run these two on your PC it should be clean of all bad boys.
If you still have problems then repeat running both again but this time do it in safe mode.
To get into safe mode reboot your PC and tap the F8 when you see the PC is booting on your screen.
If you can't seem to time hitting this key at the right time then use msconfig to get into safe mode.
On the first tab you can change it to Diagnostic Startup which is safe mode.
Run SuperAntiSpyware first and then AdwCleaner.
To get back to normal mode again run msconfig and set it to Normal Startup.
Lastly I again remind you that an up to date Antivirus software is your first line of defense.
Just removing the infections is not enough - you also need to bar the doors.
