PC Doctor Adware

What is PC Doctor?

Created by Mesa Roha Solutions LLC, PC Doctor is a rogue browser extension claiming to improve computer performance, enhance users' Internet browsing safety, and enable other similar functionality. While this browser extension may seem legitimate, be aware that it is categorized as adware or a potentially unwanted application.

PC Doctor employs a deceptive software marketing method called 'bundling' (stealth installation of additional applications together with the chosen software) to install on Internet browsers without users' consent.

After successful infiltration on Internet Explorer, Google Chrome, and Mozilla Firefox, PC Doctor generates intrusive online advertisements and monitors users' Internet browsing activity.

These intrusive advertisements include banner, in-text, interstitial, text-link, and pop-up ads. It is highly probable that clicking these ads will cause high-risk adware or malware infections.

In addition, PC Doctor monitors users' Internet browsing activity by recording various information, which may be personally identifiable such as IP addresses, unique identifier numbers, operating systems, browser types, cookies, URLs visited, pages viewed, and other similar details.

This behavior may result in adware or malware infections, and therefore, Internet users are strongly advised to remove PC Doctor from their Internet browsers. There are many rogue browser extensions similar to PC Doctor, for example, Disturbicons, Theater Mode, and Share It All.

Neither PC Doctor, nor any of these other extensions add any real value for the user - their purpose is to generate income by the display of intrusive online advertisements.

Commonly, users infect their computers with adware during download of free software via small programs called 'download clients' on freeware download websites.

Most of these websites (including download.com, softonic.com, and soft32.com) employ download clients to monetize their free services by offering installation of promoted 'legitimate' browser add-ons together with the chosen free software. Thus, reckless download and installation of freeware often results in adware or malware infections.

This situation can be prevented by closely observing each step of the freeware download process and never accepting installation of any additional programs offered. When installing downloaded software, choose the 'Advanced' or 'Custom' installation options - this will reveal any hidden applications listed for installation and allow you to decline them.

If you have already installed PC Doctor and observe intrusive online advertisements caused by this adware, read the following removal guide and eliminate PC Doctor adware from your Internet browsers.
