Guest Niels Posted December 12, 2023 Share Posted December 12, 2023 Hello, I recently got a Trojan Horse via a USB key I connected to my laptop after it was connected to another computer. At first I didn't know it was a Trojan Horse. My USB key just had new folders (weird ones: one called usbfiles, another one called Winfiles which was in fact an .exe, and a third one I can't remember the name), and after some research (and some clicks on that Winfiles folder...) I strated to figure out it could have been a virus, so I downloaded ESET Smart Security (which I had not done yet) that indicated me that my computer was infected by a Trojan Horse (hidden in a Windows-like name, stationed - if I do remember well - somewhere in C:/users/me/AppData/Roaming/...). I did a scan with ESET, it proposed me to delete the file (I accepted) and to block another one (I accepted too). But that's all. So I did other scans, and everytime ESET has no alert for me, but it tells me with orange letters that it can't open all the files. My fear is that the Trojan Horse may be in one of these files. Could you help me with that, explaining to me why ESET can't access all my files, and eventually if the Trojan Horse can still be hidden somewhere in my files. I thank you very much for this. - Niels Post scriptum: I'm French, so I do apologise if my English is not perfectly correct or if I appear rude or anything like that. That's not my intention at all.

It is normal that some files are being exclusively used by the operating system or you don't have permissions to read them. These are then reported with an error opening the file. Link to comment
itman 1,786 Posted December 12, 2023 Share Posted December 12, 2023 You should also purchase an Eset consumer product of your choice. All Eset products will prompt you upon insertion of removable media to scan the drive for malware which is a necessity when the drive has been used on any external device. Link to comment
Guest Niels Posted December 13, 2023 Share Posted December 13, 2023 Hi Marcos, Thank you for your answer. I understand that it is normal that Eset can't access the files I do not have any access myself. (A extra question here would be: if these are my files, why coulnd't I get any access to them?) But despite this being a normal situation, I am worried that a virus would, because Eset can't access these files, hide into them. Is it something possible? I thank you very much. - Niels Post scriptum: How long is the list of the files Eset and I can't access? It seems to me that the list reported is very very long. Link to comment
Guest Niels Posted December 13, 2023 Share Posted December 13, 2023 Hi itman, Thank you for your answer too. I usually never insert my removable medias on any other devices than mine. It was such an exception that I forgot I did it. But I'll consider purchasing an Eset consumer product, since I failed alone. Thank you a lot. - Niels Link to comment
Administrators Marcos 5,399 Posted December 13, 2023 Administrators Share Posted December 13, 2023 If ESET cannot access some files, then you should not be able to access them either. If you run a scan as an administrator and some files cannot be scanned, then it's highly unlikely that malware could access them. Link to comment
Guest Niels Posted December 14, 2023 Share Posted December 14, 2023 Marcos, Thank you very much for your answer. I am now reassured. Have a nice evening. Thank you again. - Niels Link to comment
