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.

VBS/Dinihou.G.2 is a component of a worm that usually is just one of several threatening programs on the compromised computer. Although VBS/Dinihou.G.2 is a new entrant into the Dinihou family of VBS-based worms, malware experts and others in the business have confirmed that VBS/Dinihou.G.2 primarily is deployed as an installer for other threats. As a precaution to block its spread to other machines, removing VBS/Dinihou.G.2 should include using strong anti-malware tools that scan all vulnerable drives, including removable ones that belong to separate peripheral devices.

When Threats Hide Behind the Names of Your Own Files

VBS/Dinihou.G.2 is one of the new entries into a family of threats that's been in development and active distribution since 2013. Like other versions of Dinihou, VBS/Dinihou.G.2 is meant to deploy other threats onto your computer, and also may open a remote connection that lets third parties issue commands to your computer. Despite the dangers posed by these attacks, VBS/Dinihou.G.2 is a relatively simple threat with low distribution numbers, and malware researchers find that adequate anti-malware protection is sufficient for blocking and removing VBS/Dinihou.G.2.

You may notice VBS/Dinihou.G.2 (or other members of its small family) by the replacement of ordinary files on affected hard drives with LNK files, which, when launched, will launch VBS/Dinihou.G.2 or related threats. These files copy the names of preexisting files on the same drive. Launching LNK files may reinstall VBS/Dinihou.G.2 or other PC threats, and malware researchers stress that files related to VBS/Dinihou.G.2 may have their file types concealed to confuse their victims. Therefore, you should avoid any interaction with suspicious files, even ones that have 'safe' file names, until the infection's removal. Displaying all file types by default is recommended whenever possible.

Giving Your Hard Drive a Well-Deserved Worm Vaccination

Although VBS/Dinihou.G.2 cannot distribute itself, its tendency to be distributed by previous threats installed just before VBS/Dinihou.G.2 makes the isolation of any infected hard drives a crucial point of security. Avoid sharing any removable devices in contact with a VBS/Dinihou.G.2-infested PC, and, in particular, avoid sharing hard drives that include unusual LNK files that show the behavior remarked upon in the last paragraph. Deleting VBS/Dinihou.G.2 and related PC threats requires generalized anti-malware solutions that scan all affected hard drives and can remove multiple, threatening files at once.

VBS/Dinihou.G.2 and other Dinihou threats may open backdoor connections that could let third parties access personal information or make threatening modifications to your computer. Malware researchers would find it safest to change any important passwords after deleting VBS/Dinihou.G.2, even if there are no immediate signs of a related account's being hacked. More than anything else, VBS/Dinihou.G.2 is a sign of how even simple, Visual Basic-based threats may continue to provide complex security headaches for PC users who don't monitor their files as carefully as would be wise.
