PUP.Mr PC Cleaner Description


Mr. PC Cleaner is a system optimization utility whose marketing methodology bears a strong resemblance to the traditional tactics of rogue file cleaners. Mr. PC Cleaner’s website sometimes is promoted through browser hijackers and adware products that modify your Web browser, seemingly in an effort to encourage you to purchase the Mr. PC Cleaner’s software. Although malware experts currently identify Mr. PC Cleaner as a Potentially Unwanted Program, its classification easily could be moved to that of a threat once additional analyzes are completed.

When Cleaning Your Computer is About Boasts More Than Hygiene


Although many invasive forms of fake system cleaners and security programs easily can be identified as misleading practices, the lines between unwanted and threatening software aren’t always clear-cut.

While Mr. PC Cleaner’s marketing points aren’t entirely truthful, malware researchers haven’t found Mr. PC Cleaner guilty of causing major security issues or attacks against PCs that have Mr. PC Cleaner installed. For now, Mr. PC Cleaner is categorized as a PUP, similar to adware or unwanted browser plugins, and its presence may be considered undesirable without being a security hazard that’s equivalent to that of an infection by a backdoor Trojan, worm or rootkit.

The PC-Cleaning Man’s Secretly Dirty Past


Even if you’re willing to overlook the exaggerations and questionable features of Mr. PC Cleaner, you may want to look askance at some of the promotional efforts that separate PC threats have used to encourage Mr. PC Cleaner’s purchase. Past attacks confirmed by malware experts have involved the installation of unrelated browser hijackers, adware and other Web browser-based PUPs that provide redirects to Mr. PC Cleaner’s website. These redirects also may block access to legitimate PC security websites, which makes them likely sources of various security problems.

Browsers being redirected to the Mr. PC Cleaner website or the unwanted installation of the actual Mr. PC Cleaner-related software should be dealt with via anti-malware tools that are designed to uninstall all types of unasked for computer products. DingoDeals and SearchDeals by Injekt are two types of adware that often are noted being installed with browser hijackers for Mr. PC Cleaner, although other PC threats also may be identified. So far, only Chrome has been confirmed to be affected by this issue, although the recent identification of this campaign (as of late 2013) makes it entirely probable that other browsers also could be modified.
