Py-installer.cc is a browser hijacker – basically a small software component that “steals” your browser’s settings. People normally notice it once their homepage, default search engine, or new tab page gets replaced without permission, and when they start seeing blank pop-ups, ads, redirects, and other obstructive content in their browsers.
The most annoying part about Py-installer.cc, or other hijackers like Holypriest.gl and Msgrouppolicy.vg, is the Managed by your organization message added to Chromium browsers. This indicates a rogue policy introduced by the hijacker that prevents users from restoring their normal browser settings.

How to Remove the Py-installer.cc Virus
Before deleting anything, collect the policy values and extension IDs linked to Py-installer.cc. You will use that information later to locate the matching entries in the system and remove them more precisely. This first part is about identifying the records that keep the browser locked down.
1. Identify the Py-installer.cc Policies
-
1.1
To confirm the presence of rogue policies, typechrome://policyinto Chrome’s address bar. If you’re using another Chromium-based browser, just swap out “chrome” for the browser’s name. - 1.2You’ll find a list of active policies here. Anything that looks like random gibberish or strings of letters in the Value column should catch your eye. Jot these down because you’ll need them in a bit.
- 1.3While you’re at it, revisit the Extensions page to gather some more info about the hijacker policy. Turn on Developer Mode, copy the IDs of all suspicious or unwanted extensions installed by the hijacker, and save them next to the rogue policy values.
- 1.4If barriers prevent you from reaching the Extensions page, try this alternative method to manually clear out extensions. Open your file explorer and navigate to this directory:
C:\Users[Your Username]\AppData\Local\Google\Chrome\User Data\Default\Extensions - 1.5
Erase everything within this folder to eliminate all installed extensions, ensuring no dangerous ones remain on your device. This action is vital for uprooting any hidden or persistent threats causing issues. - 1.6
Other browsers have equivalent directories: - 1.7Now you can go back to the Extensions Manager page in your browser.
Get Rid of Py-installer.cc Policies
This next section uses the data collected earlier to search the Windows Registry for hijacker-related policies created by Py-installer.cc. Work carefully here, because deleting the wrong registry item can affect normal system or browser behavior. If you want a safer option, the attached SpyHunter 5 tool can automate this part.
2. How to Delete Py-installer.cc Policies Through the Registry
-
2.1To access the Registry Editor, simply type
regeditinto the Start Menu and hit Enter. - 2.2Once inside, use the Edit > Find option to search for the rogue values you noted earlier. Carefully delete each entry. Repeat this process a few times to ensure nothing gets missed. It’s like weeding a garden – you don’t want to leave any roots behind.
- 2.3
If you come across entries that refuse to budge, you can adjust permissions. Right-click the problematic key, select Permissions > Advanced > Change, and grant access to “everyone.” - 2.4
Check both “Replace…” options in the previous window, then click Apply and OK.
This lets you reach the location where the rogue key can be removed.
Alternative Tools to Delete Py-installer.cc Policies
If the registry search does not reveal every policy, use the additional methods in this section. They help locate leftover hijacker entries in other policy-related locations and are worth completing even after a successful registry cleanup, because Py-installer.cc can persist through more than one configuration point.
3. Other Ways to Get Rid of Py-installer.cc Policies

Uninstall Py-installer.cc From Chrome, Edge, and Other Browsers
The browser cleanup comes last for a reason. These steps work properly only after the hijacker policies are gone, otherwise the unwanted settings may return immediately. Go through each browser area carefully, because homepage, search, startup pages, permissions, and extensions can all be altered by Py-installer.cc.
