We need to reset system restore to prevent your computer from being accidentally reinfected by using some old restore point(s). A packer is software that can compress and encrypt a program while still remaining executable. So, we set the hardware breakpoint as shown in the screenshot below: Once we run the executable after setting the hardware breakpoint, we break at the following memory location: Next, we Bring it on, malware.  Do your worst! _______________________________________________________________________________ Joshua Cannell is a Malware Intelligence Analyst at Malwarebytes where he performs research and in-depth analysis on current malware threats.

Packers can compress and encrypt the malicious program code to avoid static detection, and uncompress itself when the program is executed to reconstruct the malicious code.
