Hi.
My Eset (NOD) Anti-Virus states I have Win32/Kryptik.ASN Trojan infection. I have run SAS & Malware Remover but this infection remains. My 3 year Dell E521 SATA based Computer Freezes up after 30 minutes or quicker on heavy use such as video play. I have put in new Graphic card, swapped memory card. Ran speedfan, and all temperature low eg HDO - 40C or under. I do not thus think it is Hardware issue. I can boot to safe mode, and it appears stable.
Please can you advise on any solution, as I do not wish to re-install, and major software license keys lost, and not possible to get, as Software Company gone bankrupt.
My system restore seems to keep failing after I ran SAS & Malware remover. I also use Ccleaner which seems to allow little greater time before freeze.
I cannot see much info of this Trojan with ending .ASN. Could there be some other undectected infection ?
Thanks.

First thing I would try is booting to Safe Mode with Networking, download and install Malwarebytes from www.malwarebytes.org and let that run from Safe Mode.

Please download Dr.Web CureIt, the free version & save it to your desktop. DO NOT perform a scan yet.

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:
  • Double-click on launch.exe to open the program and click Start. (There is no need to update if you just downloaded the most current version
  • Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
  • When complete, click Select All, then choose Cure > Move incurable.
    (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • Now put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and UNcheck "Heuristic analysis" under the "Scanning" tab, then click Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
  • Click "Yes to all" if asked to cure or move the file(s) and select "Move incurable".
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)
