Windows - How to block .exe files run from specific folders with Software Restriction Policies

As you probably already know, the best way to shield your machine against malware threats is to protect the TCP layer accesses with a good Firewall and having a great AntiVirus & AntiMalware software installed, such as BitDefender and MalwareBytes (both free for personal use). For further info about how to protect your system against them, I strongly suggest to read this post. Despite these valid countermeasures, there's still a chance that you can get infected, for example if the malware manages to enter to your system by exploiting one of the various "temporary" folders provided by your OS to install new applications, unzipping compressed archives, store temp data and so on. Here's a list of the "risky" folders on a typical Windows machine: C:\Windows\Temp, which is arguably the most common executable path for viruses & malwares, and all its subfolders. %USERPROFILE%\AppData\Local\ and all its subfolders. %USERPROFILE%\AppData\Roaming\ and all its subfolders. Since all these folders are meant for storage and not for executables to run, finding a way to prevent potentially harmful .exe files from running from them would definitely be a good extra layer of defence. Luckily enough, Windows (and Windows Server) allows us to do that using the Software Restriction Policies, a set of rules that can be configured using the Group Policy Editor. To do that, search for gpedit.msc and execute it:

Navigate through Computer Configuration > Windows Settings > Security Settings > Software Restriction Policies:

If there are No Software Restriction Policies Defined, as you can see in the above screenshot, right-click to the folder node and select New Software Restriction Policies in the contextual menu. Doing that will create some new subfolders; right-click to the Additional Rules, choose New Path Rule... and enter, one after another, the paths that you want to prevent executable files to run from. Make sure to put the *.exe at the end, so that you will only block executable files.

I strongly suggest to block (at least) the following: C:\Windows\Temp\*.exe C:\Windows\Temp\*\*.exe %USERPROFILE%\AppData\Local\*.exe %USERPROFILE%\AppData\Local\*\*.exe %USERPROFILE%\AppData\Roaming\*.exe %USERPROFILE%\AppData\Roaming\*\*.exe We can see all these rules in place by looking at the screenshot below:

This will block most potentially unsafe executables from running, including those coming from archive attachments opened using the Windows built-in zip support.

Exceptions & exclusions

What if we want to allow some specific executable files to run in these folders? The answer is simple: just create an exception by adding an unrestricted entry, such as in the following screenshot:

That's about it: I sincerely hope that this post will help users, enthusiasts and administrators in making their machines more secure against the most common virus, malware and ransomware threats!   Read the full article

Pcsx2 bios not found

Pcsx2 bios not found how to#

PCSX2 - Playstation 2 BIOS (PS2 BIOS) 172320. In hardware mode, there is a graphic artifact at the bottom of the screen: However, if try to boot any game through the Chinese BIOS by a full load, then this screen will appear: And this is a log file of 'Boot ISO (full)' through.

Pcsx2 bios not found how to#

It is simple enough to configure if that is the case, I don't have experience on the newest MS garbage OS's tho, but I'm sure google can tell u how to configur those if need be. A full list of BIOS files of each console for people trying to emulate and play retro games on phone or computer. Emulator's build that you provided to me really nicely runs BIOS of SCPH-50009 with. Including Japanese original ROM, no-DRM ROM and English-patched ROMs (DRM or no-DRM). IF neither of the above simple fixs dont work and your on windows, it could only then be something like UserAccountControl or SoftwareRestrictionPolicy or whatever they may uses now these days, to restrict default profile access for security purposes. The BIOSs come in handy when you need to use one with an emulator, so you can look to this section for all your BIOS needs (Note: They also come in VERY handy for development. But it sound like the /Folder or /File were it stores the config settings is set to ReadOnly.Įither allowing your windows user profile or the system write access to the pcsx2 config folder?file?, or if the emu allows you to change the location of were to save the config settings then you could just point it to a location your profile should have write privlidges such as YourDocuments folder just for example.Ĭould alternatively maybe just execute the emu from a different directory that has write priviledge, but on modern OS's I don't think that makes a difference. Over here, we have a great selection of BIOS files for people who are trying to emulate and need a BIOS to get through.
