How to remove TechLetterSearch
Safe mode stops unnecessary applications like TechLetterSearch from running. So, you may want to start your Mac in safe mode for the next part. You can do that by starting or restarting your Mac and holding the Shift key while your Mac is booting up until you see the login screen. Next time you start your Mac, it will boot into normal mode
TechLetterSearch probably created Profiles to stop you from uninstalling it. Go to System Preferences. If there’s a Profiles icon, open it, select the profile, and press the minus button, then remove the profile.
Now try to uninstall TechLetterSearch from your applications.
If something doesn’t work, like if TechLetterSearch is still there or the profile can’t be deleted, try opening these folders (Finder -> Go -> Go to Folder) and looking for files related to TechLetterSearch:
- ~/Library/Application Support
- /Library/Application Support
It’s possible that the files are named something similar to “TechLetterSearch” but not it exactly. Look up each suspicious file name online, see if you find any stories about it being malware. If you do, go ahead and delete it.
Finally, you should be able to delete the TechLetterSearch application and browser extension (instructions at the bottom) and have it stick.
For removing malware generally (undoubtedly, TechLetterSearch came to your computer with other malware), use Combo Cleaner or another trusted anti-malware program.
You might first see TechLetterSearch on your Mac as it asks you to allow it to complete installation or to access internet connection.
TechLetterSearch is trying to hijack your web traffic, probably by modifying your proxy settings. This would let malicious actors to spy on your actions and force your browser to open malicious sites. They could also replace ads on some websites, defrauding them of a portion of their ad revenue and profiting illegitimately.
Encryption won’t keep you entirely safe because TechLetterSearch, as a browser extension, has permissions to read what you do on every website – including reading your passwords. If you use the browser infected with TechLetterSearch, you could be putting your login credentials and other private information in danger. Change your password after you delete TechLetterSearch for good.
Thanks to TechLetterSearch, your browser and other programs that use the internet may not work right. They can freeze, crash, and you might need to restart your Mac to get everything back to normal.
if you try to remove TechLetterSearch from your Applications folder, it’s likely to return in a few hours to a few days. Interestingly, it might change its name. This is something common between TechLetterSearch and a bunch of similar Mac malware programs, including SystemSpot, ActionHow, ReachChoice, and others. They morph from one to another but they all work the same.
How TechLetterSearch infects Macs
Those who got infected with TechLetterSearch and similar malware pretty consistently insist that they didn’t install anything but some software updates before they got it. This fits with the recent rise in malvertising in the form of fake software updates.
Basically, there are a ton of sites that claim that you must update your Adobe Flash media player. They show windows that loot like Mac OS system windows, so it’s easy to get fooled into thinking that you’re following the honest instructions from Apple itself. Not so – the file that gets downloaded ends up being an adware bundle. Two that I scanned on VirusTotal (link, link) got declared “Bundlore”. They install a dubious Mac optimizer and some adware on top.
And that’s how TechLetterSearch might have made it on your Mac. These fake software update sites appear on sites with goofy URLs like Mainplaceupgradesfree.info and Mainplaceofupgrades.best. They pop up on free streaming sites, mostly. Be careful when pirating TV shows and movies because those websites show a lot of malicious ads. And scan each installer with an antivirus program before you run it.
