This week we received several computer that were acting slow. After further diagnosis of the problem we found they had the following symptoms in common. After installing Malwarebytes, the update fails. If you try to install an antivirus, the install wizard reports that Windows Installer is not running.
This other symptom may be unrelated, but the frequency of computers arriving with the same problem on the same day is higher than usual. These computer all have the dreaded BSOD (Blue Screen of Death). Simply running CHKDSK /r in windows recovery console allows the computer to enter Windows again, but then the symptoms described above are exibited.
At this point performing a Windows repair fixes the system. Running tools like COMBOFIX, WINSOCKFIX, and WINDOWS RESTORE do not fix the problem.
We will continue to conduct an investigation to confirm that these symptoms are the result of a virus. We will post any results here.
