  1. I opened the attachment this morning. How do I make sure everything malicious is removed from my computer?

    • On our blog we have a few links towards security tools that will scan your computer. Run them and see if you still find any traces of the virus to be removed.

      The only problem at this time, is that the anti virus engines haven’t detected this virus yet (all the anti virus engines on Virus Total provide no detection for this when I submitted a sample). This may change within the next few hours when new anti virus definitions and updates are rolled out.

      • Thanks for replying. I’m running the Iolo virus & spyware scan now. I did find an application file in the Temporary Internet File folder named: USPS_Label_03102013″ which I’m sure is the malicious file.
