ZenoSearch – a PUP which profits from various ads

ZenoSearch ad-supported program

ZenoSearch (alternatively known as Adware.ZenoSearch, Zeno Search Assistant, etc.) is an adware-type program[1] which mostly reveals about itself by providing intrusive ads on victim's computer. This potentially unwanted program (PUP) starts running right after it infiltrates the target computer system. (Windows OS is the main target) Zeno Search virus is typically spread with the help of bundling. However, it is not as dangerous as ransomware viruses[2] and similar malware. Main problems caused by this ad-supported program are unethical advertising and unsafe redirects to third-party websites. Beware that you can be redirected to a malicious website as there is no guarantee that all links provided by this PUP are safe.

As we have mentioned, the PUP enters target devices when users are downloading other software or clicking on unsafe links that typically interrupt people while they are browsing the web. Typically, it occupies Mozilla Firefox, Google Chrome, Internet Explorer and similar web browsers right after it finishes its infiltration.

Right after the virus sets itself to run in the background of your browser, it starts promoting certain services and products by displaying ads filled with links to them during your browsing activity. According to IT experts[3], these kinds of actions can be very annoying as their main aim is to redirect victims to sponsored sites and help them increase web traffic. Due to these aims, you can find yourself on an infected domain which is not only offering goods that you don't even need but can also infect you with malware.

If these ads have been bothering you for some time, we recommend finding a reliable anti-malware tool to remove ZenoSearch from the system. Note that this adware is relatively old, so you may need trying several programs to see which one works the best. Reimage Reimage Cleaner Intego is recommended to stop unwanted ads from appearing.

After the ZenoSearch removal is done, you should refresh your browsers by resetting them according to the rules provided at the end of this post. Keep in mind that the most of annoying ads that are displayed on your screen by this program might seem tempting and eye-catching because of tracking activity which is also initiated by this adware once it infiltrates the system. The longer you keep this program on your computer, the more information it will be able to collect. So, to stop such selfish actions, eliminate the cyberthreat and all its harmful added content permanently.

ZenoSearch virus ZenoSearch usually comes with bundled software and stealthily initiates needed changes ob the system.

Ad-supported programs are spread using one main way

Most commonly, adware comes bundled with other software as free addition to the program. Such potentially unwanted programs get installed together with regular programs or after we click on the unknown link or suspicious-looking ad. Finally, you should keep in mind that you can get infected with the PUP or even a serious virus after using illegal sites, such as P2P networks or torrent sites.

To prevent unwanted software or even viruses, you need to be extremely careful while browsing the web. Make sure you ignore all pop-ups and pop-unders, no matter how tempting they look. Some of them can be completely harmless, but some of them can bring you a serious virus once clicked.

If you are willing to avoid ad-supported programs, here are the best ways to achieve this kind of goal:

  • Browse only thru sites that are legitimate or well-known[4]. These kinds of pages are typically protected from various PUPs or other harmful components;
  • If you use secondary installers or download your software from third-party sources, go to the “Custom” or “Advanced” settings and opt-out all incoming downloads that are unrecognizable to you;
  • You can install professional protection – an antivirus program and let it protect you from malware. Make sure you perform regular system scans to know if something is going wrong.

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
