How to remove SearchLetters adware

What is SearchLetters?

SearchLetters operates both as adware and a browser hijacker: it displays advertisements and promotes the address of a fake search engine by modifying certain browser settings. Users tend to install this app inadvertently through a deceptive Adobe Flash Player installer.

Therefore, SearchLetters (and other apps of this type) is categorized as a potentially unwanted application (PUA).

Adware-type apps generate revenue for the developers by serving ads (e.g., banners, coupons, surveys, pop-ups) and they commonly open dubious websites. They might also cause unwanted downloads and installations by running certain scripts. Therefore, you are advised against trusting such ads.

Additionally, SearchLetters sets the address of a fake search engine as the address of the homepage, default search engine and new tab, so that users are forced to visit this site when they open a browser, new tab, and enter search queries into the URL bar. Typically, users are unable to undo changes that were made by these apps unless they are no longer installed.

Therefore, the address of the fake search engine can be removed from browser settings by uninstalling the SearchLetters app. PUAs often collect users' browsing data (e.g., entered search queries, addresses of visited pages, IP addresses, geolocations) and other, sensitive information.

The developers might sell the details to third parties (potentially, cyber criminals) or misuse them to generate revenue in other ways. Therefore, SearchLetters can cause problems relating to browsing safety, online privacy, identity theft and other issues.

Note that, in some cases, deceptive installers (like the one that is used to distribute SearchLetters) can cause installation of malware. For example, ransomware and various Trojans. You are strongly advised against using these installers. Remove SearchLetters and any similar apps from the browser and computer.

Some examples of other apps similar to SearchLetters are MacAppsHD, Tituricsec and SearchNetLetter. They are advertised as legitimate and useful, however, they are designed only to generate revenue for the developers. They are useless and can cause serious problems. Therefore, never download or install SearchLetters or other adware-type apps, browser hijackers.

How did SearchLetters install on my computer?

People often download and install PUAs with other (usually free) programs. I.e., when PUAs are included into the download/installation set-ups as 'additional offers'. Typically, these offers are mentioned in "Custom", "Advanced", and other settings of set-ups.

Many users fail to check and change these setting when they download or install their required programs, thereby allowing PUAs to infiltrate. Unintentional downloads and installations can also be caused by clicking deceptive ads that execute certain scripts.

How to avoid installation of potentially unwanted applications

To prevent unwanted apps from being downloaded and installed, download your software only from official websites and through direct download links. Third party downloaders, installers, unofficial websites, Peer-to-Peer networks (e.g., torrent clients, eMule) and other similar channels are often used to distribute unwanted, potentially malicious apps.

Check the "Custom", "Advanced" and other similar settings of the download/installation setup and decline offers to download or install additionally-included apps. Do not click advertisements that appear on dubious web pages, since they can open other untrusted websites or even cause unwanted downloads and installations.

Remove any unwanted add-ons, extensions and plug-ins already installed on the browser immediately. The same should be applied to software of this kind that is installed on the operating system. If your computer is already infected with SearchLetters, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
