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.

How to Stay Safe Online

Here are 10 basic security tips to help you avoid malware and protect your device:

  1. Use a good antivirus and keep it up-to-date.

    Shield Guide

    It's essential to use a good quality antivirus and keep it up-to-date to stay ahead of the latest cyber threats. We are huge fans of Malwarebytes Premium and use it on all of our devices, including Windows and Mac computers as well as our mobile devices. Malwarebytes sits beside your traditional antivirus, filling in any gaps in its defenses, and providing extra protection against sneakier security threats.

  2. Keep software and operating systems up-to-date.

    updates-guide

    Keep your operating system and apps up to date. Whenever an update is released for your device, download and install it right away. These updates often include security fixes, vulnerability patches, and other necessary maintenance.

  3. Be careful when installing programs and apps.

    install guide

    Pay close attention to installation screens and license agreements when installing software. Custom or advanced installation options will often disclose any third-party software that is also being installed. Take great care in every stage of the process and make sure you know what it is you're agreeing to before you click "Next."

  4. Install an ad blocker.

    Ad Blocker

    Use a browser-based content blocker, like AdGuard. Content blockers help stop malicious ads, Trojans, phishing, and other undesirable content that an antivirus product alone may not stop.

  5. Be careful what you download.

    Trojan Horse

    A top goal of cybercriminals is to trick you into downloading malware—programs or apps that carry malware or try to steal information. This malware can be disguised as an app: anything from a popular game to something that checks traffic or the weather.

  6. Be alert for people trying to trick you.

    warning sign

    Whether it's your email, phone, messenger, or other applications, always be alert and on guard for someone trying to trick you into clicking on links or replying to messages. Remember that it's easy to spoof phone numbers, so a familiar name or number doesn't make messages more trustworthy.

  7. Back up your data.

    backup sign

    Back up your data frequently and check that your backup data can be restored. You can do this manually on an external HDD/USB stick, or automatically using backup software. This is also the best way to counter ransomware. Never connect the backup drive to a computer if you suspect that the computer is infected with malware.

  8. Choose strong passwords.

    lock sign

    Use strong and unique passwords for each of your accounts. Avoid using personal information or easily guessable words in your passwords. Enable two-factor authentication (2FA) on your accounts whenever possible.

  9. Be careful where you click.

    cursor sign

    Be cautious when clicking on links or downloading attachments from unknown sources. These could potentially contain malware or phishing scams.

  10. Don't use pirated software.

    Shady Guide

    Avoid using Peer-to-Peer (P2P) file-sharing programs, keygens, cracks, and other pirated software that can often compromise your data, privacy, or both.

To avoid potential dangers on the internet, it's important to follow these 10 basic safety rules. By doing so, you can protect yourself from many of the unpleasant surprises that can arise when using the web.
