BSOD caused by Trojan?

I've been getting some advice about causes of random BSOD we narrowed it down to HDD then I did a Virus Scan & a Trojan was picked up user Writhziden suggested I ask for help on this forum.

That is a rather old Vundo CLSID. Any reason why you didn't elect to remove it? Most frequently Vundo is a result of old/vulnerable versions of Java installed on the computer. Uninstall all Java versions except the most recent -- which should be Java SE Runtime Environment 7u4.

Scan with MBAM again:
  • Launch Malwarebytes' Anti-Malware then click the Update tab and "Check for Updates
  • Once the update has been installed and the program has loaded, select [b]Quick scan
  • When the scan is complete, click OK, then Show Results to view the results.
  • Be sure that everything is checked, EXCEPT items in System Restore as shown in this sample:
  • Click Remove Selected.
  • When disinfection is completed, a log will open in Notepad and you may be prompted to Restart. (See the Note below)
  • The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
  • Please post contents of that file in your next reply.

** Note **

If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately.
