Today doing a scan with Kaspersky Security Scan, the program found the trojan "HEUR: Trojan-Downloader.Script.Generic" the path in which it is located is "C: \ pagefile.sys". After finding it I immediately disconnected the internet (I am writing from another computer) and started to scan the PC with; Malwarebytes anti-malware, Adw Cleaner, Windows Defender (full and offline analysis), Hitman Pro, Rogue Killer (but not the most up-to-date version, because I still had to upgrade to the next version), Kaspersky Virus Removal Tool and Tdss Killer. I ran the scans even in safe mode but none of these programs reported this trojan to me. Looking for the file manually in the path that tells me Kaspersky, I can not open it, when I try it comes out a message saying "can not access the file, the file is used by another process", he tells me this even in safe mode. The point now is that I can not delete the Trojan, as Security Scan does not allow me to delete it. What do you advise me to do now? Thanks in advance for your help.

 

Small addition: I'm not the type of person who downloads random stuff on the internet, I don't use anymore program like Utorrent and when I download a file I always check the source, and if I have a doubt I also use Virus Total. I tell you this to make you understand the situation better.

 

Another addition: Using this PC I downloaded the latest version of Rogue Killer and I scanned in safe mode with him, but did not give any results. I also tried to resume a scan with Tdss Killer, but this time enabling everything in the settings except "Loaded Modules". In this scan the program encountered a threat. Going to check I saw that the alleged virus is the Intel Rapid StorageIcon exe, so I think it is a false positive.

Hi. some tools have different databases
HEUR:Trojan-Downloader.Script.Generic is a noxious Trojan that may open security "back doors", download additional malware infections and give remote attackers full control over the targeted computer system.

To be sure it is clean, let's get a deeper look... do steps 6 and 7...
Please follow this Preparation Guide and post in a new topic.
Let me know if all went well..

Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.
From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.
Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRL Team member is already assisting you and not open the thread to respond.
The current wait time is 1 - 3 days and ALL logs are answered.
If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.
To avoid confusion, I am closing this topic.
