We’ve established that anti-virus solutions detect only a fraction of the malicious software that is out in the wild.

The screen starts out appearing to scan my computer for viruses, when it really is not, and conveniently discovers numerous infection denoted by the fake Windows Security Alert. This obviously is to confuse the less sinister minds that are not in the know as to malware coder’s intentions. Now the image is clearly from the web browser Firefox but the window appears to be from a Windows Explorer environment. While surfing the internet for anti-virus solutions I came across a pretty convincing Fake Anti-Virus (FakeAV) ad.
Of the samples we discovered and examined, only 24% of all the APT malware was detected by security software.” That was enlightening to say the least that 76% of malicious software gets passed anti-virus solutions. In it Mandiant states “When MANDIANT discovers new APT malware, we scan it with the anti-virus and antimalware programs that most organizations use. In searching for documentation about anti-virus solutions success rates I discovered Mandiant’s report called M-Trends the Advance Persistent Threat (APT) ().
I wasn’t shock so much as to learn that McAfee didn’t catch it but how much more does McAfee miss or for that matter the rest of the anti-virus solutions available to the public. I also noted the submission date and it was quite recent. It turns out that McAfee doesn’t catch it. I hashed the suspicious compressed file and searched the database to see if it had been scanned previously. has McAfee within its depository of anti-virus scanning programs. After hashing the file I wanted to find out why McAfee didn’t catch it. The system had a current anti-virus solution, McAfee.
It turned out the file was from a java drive-by-download. I recently came across a virus on a system and by using time and date analysis from log entries I was able to narrow down the virus to a file, specifically a compressed file with no extension. The National Institute of Standards and Technology (NIST) Special Publication 800-83 () Guide to Malware Incident Prevention and Handling states “Because rebuilding a host is typically more resource-intensive than other eradication methods, it should be performed only when no other eradication method or combination of methods is sufficient.”

The open source ClamWin Free Antivirus software () does go as far as to say in one of its step that should be taken after an infection is to “Perform a clean install of Windows – a format of the drive *should* be completed.” This is far from coming out and recommending re-imaging all the time after an infection. The US-CERT document indicates in paragraph 5 “If the previous step failed to clean your computer, the most effective option is to wipe or format the hard drive and reinstall the operating system.” The previous steps are to run an anti-virus program on the infected system using a live compact disc. The recommendations of leading industry organizations have not completely sided one way or the other. The question might boil down to how lucky do you feel? The positive side of re-imaging is that you have thoroughly removed the suspect chance your anti-virus product is not fully cleaning after infection. Re-imaging a system is time consuming, cost ineffective and a loss of revenue and work product. This sparks the debate “re-image or not to re-image” after infection. Why should I have to re-image the system if my anti-virus is telling me that the system is clean? Anti-virus was reporting that the systems infected files had been cleaned and/or deleted. The question that was posed to me was whether or not to re-image an infected system.
