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.

Threat Level:	7/10

In attacks that echo back to the Shamoon worm variant of Disttrack, Batchwiper is a new Trojan that specializes in Iran-focused attacks for deleting large swathes of files on infected PCs. Batchwiper is most likely being distributed through removable devices, such as USB thumb drives, although other infections vectors also are entirely possible. Due to its the general lack of sophistication of its code, Batchwiper doesn't appear to be related to advanced industrial saboteur-based malware of previous Iran-targeting attacks, but SpywareRemove.com malware researchers, nonetheless, warn that Batchwiper still is powerful enough to harm any unprotected Windows PC. All efforts should be made to use anti-malware software both as preemptive protection against Batchwiper and to delete Batchwiper whenever it's necessary (and, hopefully before Batchwiper can delete anything on your computer).

How Batchwiper Merrily Erases Its Way Through the Alphabet of Your Data

Named for its usage of batch files, Batchwiper is very far from the first Trojan to attack Iran-based computers with information-destroying functions. However, Batchwiper is, structurally, a relatively primitive Trojan that doesn't appear to be related to previous high-profile threats like Flame and is unlikely to have received any clandestine backing from government-funded agencies. In spite of its limitations, Batchwiper still is a dangerous PC threat and SpywareRemove.com malware researchers don't recommend that you underestimate Batchwiper if you value the integrity of the data that's stored on your PC.

Batchwiper's primary functions involve deleting all information that's stored on your hard drive partitions D through I. As a secondary target, Batchwiper also will delete any files on the desktop of whichever account is logged in at the time that Batchwiper initiates its attack. If, in the first place, you're unable to prevent Batchwiper from infecting your PC, which SpywareRemove.com malware experts, naturally, recommend, the easiest means of saving any deleted information is to keep a regular backup that can be restored once Batchwiper is deleted. Given the history of similar Trojans in Iran, industrial and government computers most likely are Batchwiper's primary targets, although there's no reason why Batchwiper couldn't be just as harmful to a personal PC.

Wiping out the Batchwiper to Keep Your Files Safe

Possibly to avoid rapid detection before Batchwiper can distribute itself throughout various interlinked PCs, Batchwiper launches its attacks on specified dates that are spaced somewhat widely from each other. The next date for Batchwiper's scheduled atttack is the twenty-first of January 2013, although Batchwiper also has had previous dates that indicate that Batchwiper may have been in distribution for at least two months.

Batchwiper is installed by a separate Trojan dropper that should be detected and deleted by suitable anti-malware software. Actual Batchwiper infections will not display any symptoms of their presence and should be removed by either said software or a PC security expert. Given the long spaces of time between Batchwiper's attacks, SpywareRemove.com malware researchers note that habitual attention to your PC's security should allow anyone to find and remove Batchwiper before Batchwiper actually has a chance to delete any files on an infected computer.
