I am seeking guidance in permanently removing this Trojan ransomware I have acquired.
I have sought the help of a professional IT company, who ran antimalware programs (TDSS, HitmanPro, Malwarebytes, Adwcleaner) and told me that I appeared clean when my computer was returned to me. (I have already lost all of my personal files, I did not try to decrypt them, I accepted the loss and deleted all my encrypted personal files)
However, Microsoft Security Essentials keeps detecting Malware, specifically
Microsoft Security Essentials tells me that a problem is detected, cleaned, and removed. Yet, these problems continue to reoccur, continue to have to be cleaned and removed, so I know that my computer is not clean.
The symptoms of this infection include my computer running very slow, occasionally freezing, and a powershell error message.
Please help. Your assistance is much appreciated.
