Uptoabc.com is a dubious page on the Internet created to deliver sponsored content to users' computers. People get redirected to this page either by malware installed on their computers or other similar unsafe pages. When you open Uptoabc.com, the first thing you see is a message that requires you to click on an 'Allow' button to receive notifications from this website. You should not agree to receive Uptoabc.com's message, as all of them may contain broken links or scripts that may result in additional malware being installed on your machine.
Cybercriminals have set up Uptoabc.com to generate advertisements and banners that promote potentially unsafe websites and services, like adult content, online gambling, Possibly Unwanted Programs (PUPs) or fake software. The intrusive pop-ups may look in many different ways. For example, they can show up on your screen in the form of a fake alert claiming that your security software has expired and you need to renew it, or as an attractive offer for saving cash by visiting some Internet page.
If you see such messages continuously, a Potentially Unwanted Application (PUA) could have infected your device. In these circumstances, it is possible that you also are experiencing redirects to unknown pages because your browser's homepage and default search engine have been hijacked. We strongly recommend using a professional malware scanner to check your PC for malware threats.
