It's very easy to keep chugging along using the Internet, without ever thinking about things that can get downloaded to your computer, such as adware. There are thousands of applications hidden all over the Internet, trying to gain access to your computer. Quite often we don't even know we have adware on our computer until something unusual starts to happen.
Unfortunately very few people protect themselves effectively from adware, and the rest of us only think about putting some protection in place after the damage has already been done. It's very easy for adware to take advantage of Internet users who are slack when it comes to keeping their computer secure. Most of the time the adware companies are only after your Internet usage details, which probably isn't a great concern, but unfortunately there are a handful whose purpose is a great deal more sinister.
You need to get serious about your computer, and think of it the same way you would your bank account. Would you go around telling people your bank account number, plus details like your Internet banking login and password? Of course not! And yet on the Internet we may be exposing our private details, even if we do it unknowingly. It's easy to think that there's nothing lurking on our computer that we didn't willingly place there, but chances are that you have a few unwanted extras lurking in your PC. It's quite common to find that when you download a free program online, there is some sort of adware attached. After all, the software is free for you to use, so the writer wants something in return. In this case, you may download adware on purpose in order to access the software. Still, there are times when it occurs and you know nothing about it.
If you're concerned that you may have picked up some adware unknowingly, then there are free scans available online that check for the presence of adware on your PC. These are easy to use, so make sure you scan your computer regularly. Some of these scans merely identify that you have a problem, and suggest you purchase their adware removal software. Others include removal as part of the free scan. So it's worth looking around before choosing to run a scan. After all, you may find that there's nothing unexpected on your computer after all, which is great for your peace of mind.
If, on the other hand, the scan reveals things you never knew existed on your hard drive, then even if it costs you a small amount to clean it up, it's worth it to know that you've prevented someone accessing your details, who may potentially have criminal intentions.
