PerfectNav is a browser helper object that redirects users' to questionable websites

PerfectNav adwarePerfectNav is a potentially unwanted program that displays intrusive advertisements

PerfectNav is an adware[1] application that infiltrates computers as a browser helper object and starts redirecting users to suspicious websites on Internet Explorer. A potentially unwanted program usually gets in via software bundling or is installed when users click on questionable pop-up ads. Although adware is not as dangerous or harmful as malware, its presence can compromise PC security and virtual safety of an individual. 

Name PerfectNav
Type Adware
Distribution Software bundling, peer-to-peer and other file-sharing sites, etc.
Symptoms Browser is flooded with advertisements and users are redirected to questionable websites
Detection and elimination Use Reimage Reimage Cleaner Intego for a quick removal

PerfectNav adware can be injected using various deceptive techniques. Therefore, users are usually unaware that their browsers are infected. Nevertheless, they can soon notice the following symptoms:

  • error pages redirect users to PerfectNav's website;
  • browsing sessions are disturbed by pop-us, offers, deals, coupons, hyperlinks, video and other ads;
  • redirects can open several tabs at once, and they might be hard to close;
  • homepage and search engine might be altered;
  • additional components, such as browser extensions, toolbars, etc., might be installed without permission;

Due to the deceptive nature of the PerfectNav virus, these symptoms might vary, and users might experience just some of them. Nevertheless, the more PerfectNav removal is postponed, the more dangerous the browsing becomes. Therefore, security experts[2] recommend scanning the computer using Reimage Reimage Cleaner Intego or other reputable security software to make sure all the components of adware are eliminated.

The primary goal of PerfectNav is to display products or services offered by third-parties in various ways. Typically, the pay-per-click[3] scheme is used. This means that every time a user clicks on the ad (even if it was accidental), revenue is generated. In other cases, users are prompted to install bogus software (pay-per-install). Unfortunately, the promoted programs are usually useless to the end user.

Victims can often be misled by fake scans that find thousands of issues on the PC. For the less computer-savvy individual, it can seem like the software is showing genuine results. However, a closer look reveals that scareware often indicates Google cookies as potentially dangerous. 

Besides the annoying advertisements, PerfectNav adware tracks users' non-personally identifiable information, which includes IP address, sites visited, links clicked, bookmarks and similar data that contains browsing habits. The anonymous data can later be shared with the unknown third-parties for marketing purposes.

All in all, if you noticed that your browser is acting weird by continually redirecting you to suspicious sites, make sure you scan your PC and remove PerfectNav virus from your computer.

Be attentive while browsing the internet and installing new software

Users are usually unaware how questionable applications get installed on their PCs. While malware can be injected using exploit kits, malicious JavaScripts and similar techniques, adware, and other PUPs need users' intervention to be established. Therefore, please follow these simple tips to avoid unwanted apps:

  • pick your download source carefully – third-party websites can often hide questionable apps that pretend to be something they are not;
  • do not click the “Next” button several times just to be done with the installation process quickly;
  • always pick Advanced or Custom installation settings instead of Recommended/Quick ones;
  • when in Advanced mode, remove all the optional installs;
  • do not connect any external devices to your PC before scanning them with anti-malware software;
  • avoid visiting file-sharing, peer-to-peer and other suspicious domains.

Eliminate PerfectNav either manually or automatically

PerfectNav removal might be a little tricky. It highly depends on how long the adware was present on your machine. While the BHO might be easy to delete itself, it might have installed multiple other apps without your consent. Therefore, it is essential to detect all of them. Sadly, a lot of dubious apps often hide under confusing names (e.g., player.exe) or lack the uninstallation executable in general.

Therefore, we highly recommend you remove PerfectNav using security software, as it can detect all additional apps that might be present on your PC. Alternatively, you can also try to uninstall PerfectNav manually, but this process might not get rid of all additional components.

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.
