I recently had my computer cleaned by a local professional.  I currently run Panda Free Antivirus and Malwarebytes Anti-Malware (Premium).  While surfing the web in IE11, I become infected with the dllhost.exe com surrogate virus.  The only solution I've found for this issue is to run ComboFix.  I've had to clean this up a couple times now with ComboFix.


Why doesn't my antivirus software prevent the dllhost.exe com surrogate virus from taking hold?  Is there something I can do to prevent it from infecting my computer again?

:welcome: to Bleeping Computer.

ComboFix was never meant to be used as a general purpose malware scanner like SuperAntispyware or Malwarebytes' Anti-Malware which scan individual drives or different folders on a computer for malware. There are risks involved and we recommend that people should not be using ComboFix without being advised to do so by a trained expert (see here) who is assisting them deal with a malware problem.

Multiple instances of "dllhost.exe (COM Surrogate)" that spawn and consume resources is typically an indication of a Poweliks infection. More information can be found in this topic

Poweliks has reportedly been delivered through social engineering...by opening malicious spam emails that claim to be a missed package delivery from the Canadian Post or U.S. Postal Service (USPS) purportedly carrying tracking information and exploit kits that deliver drive-by downloads.
