Threat Metric
The Threat Meter is a malware assessment that SpywareRemove.com's research team is able to
give every identifiable malware threat. Our Threat Meter includes several criteria based off of
specific malware threats to value their severity, reach and volume. The Threat Meter is able to give
you a numerical breakdown of each threat's initial Threat Level, Detection Count, Volume Count,
Trend Path and Percentage Impact. The overall ranking of each threat in the Threat Meter is a basic
breakdown of how all threats are ranked within our own extensive malware database. The scoring for
each specific malware threat can be easily compared to other emerging threats to draw a contrast in
its particular severity. The Threat Meter is a useful tool in the endeavor of seeking a solution to
remove a threat or pursue additional analytical research for all types of computer users.
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.

We had a variant infitceon as well. Here are our are findings so far:This virus has its lock program under c:\security lock . Using a boot CD (running Mini XP) I removed the registry setting (HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Run\svchost) that was running the svchost.exe file in that folder and also renamed it. After that the server was able to boot. I then reconfigured the NIC back to its original settings and restored network access.I also found another folder c:\decrypt lock . It has two files. decrypt.exe and decryptedfilelist.list. Open the latter in note pad and you see every file that has been locked out via above method. Those files are indeed password protected zip files it seems, but the password in the blog doesn't work. I am needing this password as well. How can it be obtained? Next it'd be good to run a script against the list of encrypted files and have them decrypted.I also saw a process called aes256crypter.exe running in task manager. Could not kill the process, but was able to find the executable in C:\ProgramData\mssupport i believe. I renamed it as well and it stopped running.Lastly, I saw the undxkpwvlk.dll and a batch file that changes the NIC IPs in c:\programdata\systemfiles which I renamed as well for now
