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/Autorun.worm.aapn!lnk is a worm that distributes itself through peripheral hard drives, such as USB flash drives. This allows VBS/Autorun.worm.aapn!lnk to create 'backup' copies of itself, as well as compromise other computers that share their storage devices with your machine. Since VBS/Autorun.worm.aapn!lnk is built to launch and install itself automatically, malware researchers consider the best protection against VBS/Autorun.worm.aapn!lnk to be ongoing anti-malware security, which should be able to detect and block VBS/Autorun.worm.aapn!lnk before VBS/Autorun.worm.aapn!lnk may install itself.

A 'Basic' Threat that Wants to Reproduce Through Your USB Stick

VBS/Autorun.worm.aapn!lnk is a recently-identified worm based on Visual Basic Script. Because VBS/Autorun.worm.aapn!lnk was confirmed only in 2014, its distribution currently is estimated to be low throughout the globe. However, its primary functions, which help to define VBS/Autorun.worm.aapn!lnk as a worm, may allow that to change in the near future.

Like any worm, VBS/Autorun.worm.aapn!lnk creates 'copies' of itself, which may allow VBS/Autorun.worm.aapn!lnk to be distributed to new computers or to prevent itself from being completely deleted. Malware researchers have confirmed that VBS/Autorun.worm.aapn!lnk targets USB-based devices as primary locations for its copies. Other PCs that access any VBS/Autorun.worm.aapn!lnk-infected devices may be subjected to VBS/Autorun.worm.aapn!lnk's 'Autorun' routine, which will, in turn, infect these new machines.

Other functions from VBS/Autorun.worm.aapn!lnk still are being examined. However, worms like VBS/Autorun.worm.aapn!lnk tend to involve the deliberate termination of critical security features, particularly network-based ones that would block crooks from remotely controlling your computer. VBS/Autorun.worm.aapn!lnk also may install additional threats with other functions, and has no evident symptoms to alert its victims.

Closing the Tunnels that a Worm Uses to Burrow to Your Hard Drive

VBS/Autorun.worm.aapn!lnk hasn't shown evidence of including any highly-visible attacks, and may be difficult to detect without any use of appropriate anti-malware tools. You should assume that any unprotected PC that accesses a potentially VBS/Autorun.worm.aapn!lnk-infected USB device also is infected until anti-malware scans can determine any differently. VBS/Autorun.worm.aapn!lnk and other worms may be detected in multiple copies, and removing all these copies, preferable through standard anti-malware solutions, is required for a complete disinfection of your PC.

To guard against VBS/Autorun.worm.aapn!lnk being reinstalled from secondary copies of itself, malware researchers recommend that removing VBS/Autorun.worm.aapn!lnk utilize system scans that access all available hard drives. Scanning your peripheral devices alongside your built-in hard drives will offer VBS/Autorun.worm.aapn!lnk as little room for concealing itself as possible. Using other, relevant security features, such as Safe Mode, also may be necessary.

VBS/Autorun.worm.aapn!lnk is a worm that was detected extremely recently, although its basic style of attack has been seen in action for years. Updating your security software routinely always is recommended, but, in the case of new threats like VBS/Autorun.worm.aapn!lnk, may be mandatory before you're able to detect VBS/Autorun.worm.aapn!lnk at all.
