As you know there are multiple ways of recovering the files even after it was deleted. I have a USB 8GB pen, it contains many files, one of them I would like to delete it. if I clicked on move to the trash, of course, it's going to move the file from the external pen drive to the local storage. and I don't want that.
What if I installed an .exe game with a trojan using wine on my Ubuntu? Would this allow the hackers to hack into my device just like what happens usually on Windows? What about the viruses that work behind the scenes in the background, backdoors, the trojans that store a file inside the registry, startup folder and I don't know what else -- will my Ubuntu be hacked just like what happens in Windows?
Extra question: Should I install anti-virus on my Ubuntu?
I want to have only 2 partitions: the 238GB as shown in the picture, and the 262GB, But there is an anonymous "Free space 2.1MB" is coming from somewhere I don't know. I don't know how to merge it with the 262GB free space because it should be coming from there not from the 238GB Part; Mean: the 2.1MB should be a part from the 262GB partition, but I'm not sure.
On the another window (the installation type window) it's showing that I have only 2 partitions.
I don't know which window I should believe. But I want to get rid of this 2.1MB in some way.
But I don't want to lose the data stored in the 238GB partition
I have 2 partitions, my system file, swap.. every thing is on the partition which named now (free space) because I clicked the [-] button. The second partition is the partition where I usually store some important data in and I don't want to erase it.
What I want to do is to Erase the partition which called (free space) safely, mean if someone installed photoRec for example he will not be able to recover my old files. I found here on this website many answers, but all of what I found guides the user to erase all of his disk; but I don't want to do that, I just want to erase one partition, because the secret data is stored there (in free space). I don't know what is the name of this method, maybe it's replacing the free data on the partition with zeros, (I don't know but want the safest). Another question: the hacker can't recover the files on my partition (free space) after erasing it safely even if the another partition (/dev/sda4 ntfs) is still on my device without erasing, true?
Uninstalling using the method:
dpkg --list
sudo apt-get remove “package-name”
sudo apt-get purge “package-name”
sudo apt-get autoremove
is a beautiful way, but the problem is in searching for the package which I really need to uninstall inside all of this long dpkg --list , and this is not the fatigue, you will get enough fatigue when looking for the true name of the true package which you want to remove.
-are there any way much easier than this? -are there any software like Iobit uninstaller which is on Windows? mean: software for uninstalling programs on Ubuntu? -are there any way to get the true name of the package which we want to remove?
