Title: Avast Free Failed to detect HDD Low Malware
Post by: estinson on December 30, 2010, 05:04:43 PM

System is now clean, but Avast did not detect this at all. It also had infected Adobe Reader Speed launcher (Version 7) executable and was re-installing via this exe. I am unsure of original infection vector, maybe a PDF exploit (guess) since the version of Acrobat is old. This was a customers PC, I can only recommend they upgrade that software but I doubt they will.
Latest version of Avast Free is installed and up to date.

Oh! Sorry about the incorrect posting spot. Unfortunately I do not have a sample to submit, I had to get the system clean and back out the door. I first tried removing it manually, but it came back so I used rkill and MBAM to fully clean it.
Using RKill is what pointed me to the infected acrobat speed launcher executable.
