Topic: If you format a pc, does it make it purely clean? - page 2. (Read 350 times)

Sounds like those recommending deleting system32 files to solve some minor/ major issue

Actually that's wrong. If you have a virus on another partition you won't clean it by formatting C:. You have to format the other partition as well.

But, as boyptc said,


Thus, a bad actor could retrieve some of your infected files and if these files are recovered, your PC will be infected again. Some programs (such as Recuva Undelete) can recover deleted files because they are not actually deleted. When you delete a file it is only marked as deleted (and Windows doesn't see it anymore), but at physical level the file is still there. And it will stay there until you will write another file exactly on the place where the deleted file was placed on your HDD.

If you want to make sure that none of the deleted (formatted) data can be recovered, you a need a special software. This software seems to be wiping your HDD but in reality it does more than that: it deletes everything from your HDD and then it fills it with garbage data, then it deletes also this garbage data. As a consequence, your previous files can't be recovered anymore, as after they were deleted, in their place garbage files were written, making impossible to retrieve what was there before the junk files. You can find many such file shredders on the Internet, a very common one being CCleaner.

Regarding reinstalling Windows, it is recommended to fully format your drive at the installation (don't use quick format) and make sure you don't have the network cable plugged in your PC until you finish the installation and you have an antivirus installed. So it's better to have the antivirus kit on an USB stick, then you reinstal your Windows without being connected to Internet; after Windows is installed you install your antivirus and only after you connect your computer to Internet. After that, you should install your drivers (chipset  SATA, RAID, etc.) and then install any other program you wish. This is a better approach as while you are installing Windows you don't have an antivirus protection and if your PC is connected to the network / Internet it is vulnerable in this period.

If you format the PC not only the virus but the PC will be much clearer, but only those that are in the C drive will be formatted Not everything on the PC will be formatted. After cleaning the PC you can reinstall everything from the software file or hard drive.

Yes reformatting your pc makes it 100% clean away all your files ,then right after reinstalling your software be sure to run your antivirus software.

Formatting C drive is just enough to make your PC clean which means reinstall your OS completely not in upgrade mode.

Once you reinstalled it,better subscribe for a good antivirus to keep your device safe from virus.

Wipe your drive with CCleaner or BleachBit. Wipe it from a second computer. If you are scared about something remaining after the wipe, wipe again. Wipe 35 times if you have very sensitive data you are trying to destroy, but one wipe should really be enough. Then format and reinstall your OS.

If its the files that you regularly access which some of them will connect to its repository then its not going to be clean even if you kept reformating your PC. The rat will always activate and download when its connected to the internet. What you need is clean your files, clean it first for malware before reinstalling fresh.  All I can say is that its hard to use Windows when you kept downloading files online, it will just keep coming back. Switch to Linux.

I'm not that expert guy but I'd say it's the most effective thing to remove viruses completely.

But for files, even you reformat many times. There are software that can retrieve data from your hard drive.

Does it? I'm not expert with the viruses...
