What is the PDFPower?

PDFpower is a malicious program, that takes control of your browser’s homepage and search engine, inundating your online experience with unwelcome advertisements devoid of any connection to the websites you intend to explore.

Furthermore, PDFpower acts as a browser hijacker that forcefully redirects your search queries through questionable search engines. Additionally, it initiates the automatic opening of new tabs in your browser, bombarding you with ads promoting software sales, counterfeit software updates, and deceptive tech support schemes.

PDFPower is associated with an unwanted program named MediaArena, which exhibits suspicious behavior similar to spyware. This program raises significant concerns due to its ability to covertly monitor user activity, capturing all keyboard and mouse clicks performed on the system. Moreover, MediaArena can take screenshots and transmit them to a remote command server. These activities strongly indicate the malicious intent of this program.

Another worrisome aspect is the modifications made to the browser when MediaArena is installed. Upon execution, the program opens the default browser and redirects it to the goto[.]searchpoweronline[.]com page. Additionally, MediaArena changes the default search engine to this page, potentially exposing all search queries to the operators of the website. This is yet another undesirable element of the program. Furthermore, PDFPower has the ability to spread itself to removable drives, which can be an unpleasant surprise for unsuspecting users who may inadvertently come into contact with it.

How dangerous is the PDFPower.exe?

Keystrokes logging performed by the PDFPower.exe may expose your login credentials

First off, PDFPower.exe will make your routine browser activities way harder. Aside from the aforementioned changes to the preferred search engine, malware also adds advertisements to all pages you visit. And don’t forget that anything you type is almost instantly transferred to hackers who stand behind the PDFPower malware. Some say privacy concerns are overestimated, but in this case you share almost every detail of your activity with a third party. Even for the least caring person, it is intimidating and unbearable.

“Visible” damage is not a single unpleasant thing MediaArena PUA does to your system. To make its running process more convenient, malware changes a lot of Windows settings. To conduct all malevolent operations effectively, it wrecks the protection components and adjusts Group Policies. You will likely see your Microsoft Defender disabled – malware halts it to prevent recognition. If you open the HOSTS file, you will likely see several new entries – this malware brings them in to ease the connection to the C2 server. All these adjustments shall be reverted to the original in the process of PC recovery.

How did I get the PDFPower?

Unwanted programs are commonly spread via unwanted ads and in software bundles

Unwanted programs in their spreading model are pretty similar to adware and browser hijackers. In some cases, they spread each other by throwing users to deceiving websites or by showing them malicious ads. Any interaction with such pages or ads can infect your system with more and more malware. At some point, the system may become unusable just because it is clogged with blinking ads and constantly opening browser tabs.

The example of malicious banners you can see in the Internet

Another method through which this entity can infiltrate your computer is by being downloaded from an unreliable website, often as a component within a software bundle. Individuals who distribute compromised versions of popular software (which don’t require a valid license key) have limited opportunities for monetary gain. Consequently, there exists a strong incentive to append other applications to the final package of the compromised software, earning compensation for each installation.

Before passing judgment on these individuals for engaging in hacking and disseminating malware, it’s essential to consider whether resorting to this method to avoid purchasing the software is acceptable. Opting for a one-time payment of $20-$30 proves far more economical than bearing the considerably larger cost of system recovery later on.

How to remove the PDFPower from my PC?

The best way to get rid of this is to use anti-malware software

Removing such a virus requires the use of specific software. Good anti-malware programs should have high efficiency at scanning and be lightweight – to create no problems with usage also on weak computers. Furthermore, it is better to have on-run protection in your security solution – to prevent the virus even before it launches. Microsoft Defender does not have these functions for different factors. That’s why I’d advise you to use a third-party anti-malware program. GridinSoft Anti-Malware is an ideal option that fits each of the specified qualities.1

Before the malware removal, it is important to boot your Windows into Safe Mode with Networking. Since PDFPower.exe applies numerous detection evasion tricks, it is necessary to halt it before launching the security program.

Booting the PC into Safe Mode with Networking

Press the Start button, then choose Power, and click on Reboot while holding the Shift key on the keyboard.

Boot into Windows Safe Mode

Windows will reboot into recovery mode. In that mode, choose Troubleshoot→ Startup Settings→ Safe Mode with Networking. Press the corresponding button on your keyboard to choose that option.

When your system is in Safe Mode, all third-party applications and most non-crucial system components are not started with the system start. That gives you the ability to clean the system avoiding any problems in the process.
