Hello!
A few days ago i have installed a program that can merge several pdf files into one. however, after installing it, i soon started to get many many many ads! they show up on my screen as soon as I launch web browser. they are named “ads by Terraclicks”. I don’t remember installing any Terraclicks. What happened?
Terraclicks program is an untoward software which uses hijacking techniques to get into users computers. It spreads alongside freeware and shareware as a "recommended download." Unfortunately, many computer users install such computer parasites without realizing that because they tend to rely on Default and Standard installation settings. You should not do so; in fact, you should always opt for Custom or Advanced settings and configure software's elements the way you want.
Now that Terraclicks virus has already infiltrated into your computer system, ads by Terraclicks show up repeatedly and annoy you every day. To block these ads, you need to remove Terraclicks from your computer. You can find comprehensive removal instructions in this article - Terraclicks virus. How to Remove? (Uninstall Guide)
