What do you know about 1stBrowser?
1stBrowser is classified as a potential unwanted program (also called PUP) with the traits of an adware. It claims to help you with your downloading, but it brings troubles instead. This program can become available easily when downloading and installing some free programs carelessly. You also may be fooled by its words and lead it to your PC yourself. After it entered your system, you'll have to bear its tons of unwanted ads. The ads can appear on almost every page you visited no matter you're using Google Chrome, Mozilla Firefox or Internet Explorer. You need to get rid of it.
