Threat Metric
The following fields listed on the Threat Meter containing a specific value, are explained in detail below:
Threat Level: The threat level scale goes from 1 to 10 where 10 is the highest level of severity and 1 is the lowest level of severity. Each specific level is relative to the threat's consistent assessed behaviors collected from SpyHunter's risk assessment model.
Detection Count: The collective number of confirmed and suspected cases of a particular malware threat. The detection count is calculated from infected PCs retrieved from diagnostic and scan log reports generated by SpyHunter.
Volume Count: Similar to the detection count, the Volume Count is specifically based on the number of confirmed and suspected threats infecting systems on a daily basis. High volume counts usually represent a popular threat but may or may not have infected a large number of systems. High detection count threats could lay dormant and have a low volume count. Criteria for Volume Count is relative to a daily detection count.
Trend Path: The Trend Path, utilizing an up arrow, down arrow or equal symbol, represents the level of recent movement of a particular threat. Up arrows represent an increase, down arrows represent a decline and the equal symbol represent no change to a threat's recent movement.
% Impact (Last 7 Days): This demonstrates a 7-day period change in the frequency of a malware threat infecting PCs. The percentage impact correlates directly to the current Trend Path to determine a rise or decline in the percentage.

Koobface is a worm that infects computers by using the messaging system of social networks like Facebook and MySpace. Other Koobface known variants are Boface, W32.Koobface, Net-Worm.Win32.Koobface.b, and W32/Koobface. The Koobface worm attacks profiles by sending an email to a user's Facebook inbox with subjects like "You look just awesome in this new movie" or "You look funny in this new video" and the email message provides a link to a malicious video website. The malicious video website will prompt the user to download the fake video codec file flash_player.exe under the assumption that the user needs to update the Flash program to view a video. The flash_player.exe is really a doorway meant to let Koobface infect your computer.
Once installed, Koobface downloads a program called tinyproxy.exe. Tinyproxy.exe loads a proxy server called Security Accounts Manager which Koobface uses to monitor traffic on TCP port 9090 and proxies all outgoing HTTP traffic. Koobface hijacks search results from search engines like Google, Yahoo, and MSN and replaces the results with links of malicious websites.
Koobface may redirect you to malicous websites that sell rogue security tools. Koobface has the ability to recreate itself after reboot. It is strongly recommended to remove Koobface from your system upon detection.

My computer wont allow me to download spyhunter and when I manually try to find in computer or all harddrives "Koobface" is not found. Please help me. Thank You, John Myers
I have received all of the warnings this week about some kind of password stealing trojans being on my computer and then for $99.00 purchased Avast to fix the problem, and on my laptop another bunch of crap is going on and I purchased a program for $49.00 yesterday on Reg tool and am still trying to get it to work properly. I am so pissed, because I currently lost my job last week and I sure didn't need to spend that money.
my computer is not opening facebook due to virus. please help me to remove virus from my computer.
My wife's laptop downloaded all sorts of things and she could not get to anything, we called Microsoft Support and they charged us 299 to run both her computer and my laptop to look for and fix koobface. In Feb we had a similar infection and the microsoft group charged 99 dollars and their fix did not work, so they tried again and it worked so I filed a complaint with my credit card company. That is currently in litigation. I am a retired service member living on my retirement and i find by looking up this worm, everyone has a fix? I am very concerned with Microsoft. I tried their MRT program and it appears to do the same thing that their fix did and it was free. Daily I run CCleaner followed up by malware bytes. This really haunts me.
