Micprosorce.com is a browser hijacker that redirects your web searches and homepage to a deceptive search engine designed to look like a legitimate service. Once installed, this unwanted software modifies your browser settings without permission, forcing every new tab and search query through its own pages to generate advertising revenue. While not as destructive as ransomware or data-stealing trojans, browser hijackers like Micprosorce.com disrupt your browsing experience, expose you to potentially malicious advertisements, and can serve as a gateway for more serious infections.
This hijacker typically arrives bundled with free software downloads or disguised as a helpful browser extension. Users often discover the infection when their familiar homepage suddenly changes or search results begin routing through unfamiliar domains. The good news is that Micprosorce.com can be removed with systematic steps, though it employs several persistence mechanisms that make simple uninstallation insufficient.

How It Spreads
Micprosorce.com rarely advertises itself honestly. Instead, it piggybacks on software you actually want to download. The most common infection vector is bundled freeware — when you download a free PDF converter, video player, or system utility from a third-party download site, the installer often includes "optional offers" that are pre-checked or presented in confusing language. Users who click through installation screens quickly without reading each step frequently end up with browser hijackers like Micprosorce.com installed alongside their intended software.
Another frequent distribution method involves fake update notifications. You might encounter a pop-up claiming your Flash Player, Java, or browser is out of date, with a prominent download button. Clicking this button doesn't install the legitimate update — it downloads an installer package that includes the hijacker. These fake update pages are designed to mimic the appearance of real software update prompts, making them particularly effective against less technical users.
Specific distribution channels for this hijacker include:
- Bundled software installers from download portals that monetize free software by including third-party offers
- Fake download buttons on freeware sites that look like the real download link but actually trigger unwanted software
- Deceptive browser extension offers presented as shopping assistants, coupons, or enhanced search features
- Compromised websites serving malicious ads that trigger automatic downloads when clicked
- Email attachments disguised as invoices or shipping notifications that include installer payloads (less common for this specific threat)
- Torrent files and cracked software that bundle hijackers with pirated programs
What It Does On Your Machine
Once installed, Micprosorce.com immediately modifies your browser configuration. Your homepage changes to micprosorce.com or a related domain, and your default search engine switches to this hijacker's service. Every new tab you open may display the hijacker's page instead of your chosen blank page or speed dial. When you search using your address bar or search box, queries route through the hijacker's servers before eventually delivering results — often pulled from legitimate search engines like Bing or Google, but surrounded by additional advertisements the hijacker injects.
The hijacker maintains its presence through several technical mechanisms. It typically installs as a browser extension with a innocuous-sounding name or a random string of characters. Even if you notice this extension and disable it, the hijacker often modifies your browser shortcut targets to include command-line parameters that force the hijacker page to load on startup. Registry entries are created to set the hijacker as a policy-controlled homepage, making it difficult to change settings through normal browser preferences. Some variants also create scheduled tasks that periodically check if the hijacker is still active and reinstall it if components are missing.
Beyond the annoyance of unwanted redirects, Micprosorce.com collects information about your browsing habits. This includes every search query you enter, the websites you visit, how long you spend on various pages, and technical details about your system. This data feeds into advertising profiles that make the injected ads more targeted, but it also represents a privacy concern — you have no control over how this information is stored, who has access to it, or whether it might be sold to third parties.
The advertisements displayed through the hijacker pose their own risks. Because the hijacker operators prioritize revenue over user safety, the ad network may include malicious advertisers. Clicking on these ads can lead to phishing sites designed to steal credentials, tech support scam pages that claim your computer is infected, or additional malware downloads. The hijacker essentially turns your browser into a revenue-generating tool for its operators while degrading your security posture and browsing experience.
Manual Removal — Step by Step
Disconnect from the Internet
Unplug your ethernet cable or disable Wi-Fi to prevent the hijacker from communicating with its command servers or downloading additional components. This also protects you from accidentally clicking malicious ads during the removal process. You can reconnect once you've verified the infection is completely removed.
Uninstall Suspicious Programs
Open Settings → Apps (or Control Panel → Programs and Features on older Windows versions). Sort by installation date and look for unfamiliar programs installed around the time the hijacking started. Remove anything you don't recognize, particularly entries with generic names, random character strings, or anything mentioning search, browsing, or coupons. Common bundled program names change frequently, so trust your judgment about what you actually installed.
Remove Browser Extensions
Open each installed browser and check the extensions/add-ons page (chrome://extensions/ for Chrome, about:addons for Firefox, edge://extensions/ for Edge). Remove any extensions you didn't intentionally install, particularly those with vague names, recent installation dates, or permissions to "read and change all your data on websites." Disable "Developer mode" in Chrome if it's enabled — hijackers sometimes enable this to prevent easy removal.
Check and Repair Browser Shortcuts
Right-click your browser shortcuts (on desktop, taskbar, and Start menu) and select Properties. In the Target field, remove anything after the .exe filename — the hijacker often adds parameters like "--homepage=http://micprosorce.com" to force the page to load. The target should end with "chrome.exe" or "firefox.exe" with nothing following it except possibly a closing quotation mark. Apply changes and repeat for all browser shortcuts.
Reset Browser Settings
In each browser, access settings and perform a full reset. In Chrome, go to Settings → Reset settings → Restore settings to their original defaults. In Firefox, go to about:support and click "Refresh Firefox." In Edge, Settings → Reset settings → Restore settings to their default values. This removes the hijacker's policy entries and restores your original homepage and search engine. You'll need to reconfigure any custom settings afterward.
Remove Registry Entries
Press Windows+R, type "regedit" and press Enter. Navigate to HKEY_CURRENT_USER\Software and HKEY_LOCAL_MACHINE\Software and look for folders with suspicious names or references to Micprosorce. Also check HKEY_CURRENT_USER\Software\Policies and HKEY_LOCAL_MACHINE\Software\Policies for browser policy entries. Delete any entries related to the hijacker. Be cautious — deleting wrong registry entries can cause system problems. If you're not comfortable with this step, skip to the scanner in step 7.
Check Task Scheduler
Press Windows+R, type "taskschd.msc" and press Enter. Expand Task Scheduler Library and look through the list for scheduled tasks with generic names, random characters, or creation dates matching the infection timeframe. Select suspicious tasks, view their Actions tab to see what they execute, and delete any that reference the hijacker's folder or reinstallation scripts. Hijackers use scheduled tasks to resurrect themselves after removal attempts.
Scan with Malwarebytes
Reconnect to the internet and download Malwarebytes Free from malwarebytes.com (be sure you're on the legitimate site). Install and run a full "Threat Scan." This will catch components you might have missed, including browser hijacker remnants, tracking cookies, and any bundled PUPs that came with Micprosorce.com. Quarantine all detected items and restart when prompted.
Change Your Passwords
If you entered passwords or visited financial sites while the hijacker was active, change those passwords from a clean device or after confirming removal. While browser hijackers typically don't include keylogging functionality, the ones that display malicious ads could have exposed you to credential-stealing phishing pages. Better safe than compromised.
Restart and Verify
Restart your computer and open each browser. Verify that your homepage and search engine are what you expect, that no unfamiliar extensions have returned, and that searches aren't redirecting through suspicious domains. Visit several sites and watch for unusual pop-ups or behavior. If the hijacker returns after restart, you likely missed a persistence mechanism — consider bringing the computer to our shop for thorough cleaning.
Prevention
- Download software only from official sources. Use the actual developer's website rather than third-party download portals. Sites like Download.com, Softonic, and similar aggregators often bundle unwanted software with otherwise legitimate programs.
- Read installation screens carefully. Use "Custom" or "Advanced" installation options instead of "Express" or "Recommended." Uncheck any boxes offering to install toolbars, change your homepage, add browser extensions, or install "partner offers." These boxes are often pre-checked and worded deceptively.
- Keep your software updated through official channels. Enable automatic updates for Windows, your browsers, and security software. Ignore pop-up messages claiming you need to update — legitimate updates come through the software's own update mechanism, not through random web pages.
- Use an ad blocker. Extensions like uBlock Origin reduce exposure to malicious ads that lead to hijacker downloads. Many infections start with a single deceptive ad click on an otherwise legitimate website.
- Review browser extensions regularly. Once a month, check what extensions you have installed and remove anything you don't actively use. Hijackers sometimes install themselves as extensions with permissions that let them control all aspects of your browsing.
- Maintain reputable security software. Windows Defender provides baseline protection, but adding Malwarebytes Premium or a similar anti-malware tool provides an extra layer specifically tuned to catch PUPs and hijackers that traditional antivirus might miss.
- Be skeptical of "too good to be true" offers. Free VPN services, dramatic coupon finders, video download helpers, and similar utilities are common hijacker disguises. If a browser extension or program seems to offer amazing features for free, research it thoroughly before installing.
- Create a separate limited user account for daily use. Running as a standard user rather than an administrator makes it harder for hijackers to modify system-wide settings or create scheduled tasks. You can always elevate to admin when you need to install legitimate software.
