What is Offers4U?

Offers4U is advertised as a program that displays coupons for sites you are visiting and competitive prices when you are viewing product pages at sites like Amazon. Though this may sound like a useful service, the Offers4U program can be intrusive and will display advertisements whether you want them to or not.
When installed, the Offers4U browser extension will display advertising banners, pop-up advertisements and in-text ads, stating that they are brought to you by “Offers4U”. The Offers4U Ads will have different text under the pop-up: “Powered by Offers4U”, “Brought to you by Offers4U”, “You’ve received a premium offer from Offers4U” or “Ads by Offers4U”.

These ads are aimed to promote the installation of additional questionable content including web browser toolbars, optimization utilities and other products, all so the Offers4U publisher can generate pay-per-click revenue.

When infected with Offers4U the common symptoms include:

  • Advertising banners are injected with the web pages that you are visiting.
  • Random web page text is turned into hyperlinks.
  • Browser popups appear which recommend fake updates or other software.
  • Other unwanted adware programs might get installed without the user’s knowledge.

How did got Offers4U on my computer?

Offers4U is an adware program that is commonly bundled with other free programs that you download off of the Internet.
Unfortunately, some free downloads do not adequately disclose that other software will also be installed and you may find that you have installed Offers4U without your knowledge.
You should always pay attention when installing software because often, a software installer includes optional installs, such as this Offers4U adware. Be very careful what you agree to install.
Always opt for the custom installation and deselect anything that is not familiar, especially optional software that you never wanted to download and install in the first place.
It goes without saying that you should not install software that you don’t trust.
