What is 4solo.biz

4solo.biz (1solo.biz, 2solo.biz, 3solo.biz, 9solo.biz, solo7.biz) is another example of a browser-based scam that attempts to force users into clicking on the “Allow” button. Websites of such type can be visited inadvertently as a result of clicking on deceptive ads or banners, however, if you are constantly witnessing this page at the browser startup, chances are your PC is infected with adware. Developers of such pages exploit delusive headings like “Confirm you are not a robot”, “Pass Captcha”, “Click Allow to download a file”, and others. If you followed their commands, then you might be experiencing a stream of ads on your desktop. Note that such ads can contain malicious redirects that may cause additional infections and steal your data away. Luckily, 4solo.biz is easy to remove with the help of our guide mentioned below.

How 4solo.biz infected your computer

Potentially unwanted programs (PUPs) like adware or browser hijackers can end up on your computer due to suspicious downloads. For instance, thousands of users download freeware programs each day. Most of them are repacked by developers and bundled with third-parties software. That software is typically presented in “Advanced” or “Custom” sections that often get skipped. Unfortunately, because extortionists pre-set those offers for automatic installation, most users appear infected by PUPs that adjust multiple settings leading to identity threat. To prevent infiltration of such type, you should avoid clicking on suspicious ads and downloading software from shady resources.
