In the last couple of weeks we’ve seen a few infections pop up that were propagated via Adobe PDF files. The origin of these attacks seems to be from certain ads linked to delzzerro.cn and updatedate.cn. You will generally get a prompt to download or open a document called a PDF which is used with Adobe Acrobat Reader for a variety of purposes. This particular infection uses an exploit in this software to spring a trap on an unwary user which then allows the virus to install a fake antivirus program like the one shown in our Malware section above.

Ways to avoid infection:

  1. Keep Antivirus Software up to date
  2. If you are prompted to download an Adobe PDF document that you were not expecting, do not click “OK”
  3. Be sure to manually re-scan any PDF files with odd names like “536.pdf” or “856.pdf” or something similar
