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:	8/10
Infected PCs:	0

TrojanDownloader:Win32/Small.gen!I is a heuristic identifier for threatening software that includes functions for downloading and installing additional threats. The presence of TrojanDownloader:Win32/Small.gen!I may result in backdoor vulnerabilities, attacks by information-logging spyware or other harmful software beyond the scope of TrojanDownloader:Win32/Small.gen!I's personal capabilities. TrojanDownloader:Win32/Small.gen!I has been observed including defenses against some deletion measures, and malware experts advise using all anti-malware solutions at your disposal to remove TrojanDownloader:Win32/Small.gen!I and any software TrojanDownloader:Win32/Small.gen!I installs.

Following from One Trojan to the Next

TrojanDownloader:Win32/Small.gen!I occupies the same set of functions as TROJ_CHEPRO.CPL, DGA.Changer and other Trojans purposed specifically for installing new threats. Unlike those two examples, TrojanDownloader:Win32/Small.gen!I is a generic or behavior-based detection, which allows its payload to show significant diversity between two, separate attacks. While TrojanDownloader:Win32/Small.gen!I is most likely used for installing high-level threats such as Remote Access Tools, banking Trojans or rootkits, TrojanDownloader:Win32/Small.gen!I also may install adware and other PUPs. Common dangers from these attacks may include:

Losing information, such as bank account credentials, credit card numbers or other account passwords.
Performance slowdowns also may hamper your software's productivity and performance.
Your PC may be used to distribute threats like TrojanDownloader:Win32/Small.gen!I to other PCs, traditionally through an e-mail botnet that harvests your stored e-mail addresses as new targets.
In rare cases, permanent hardware damage may be suffered from the installation of Bitcoin miners and other Trojans that use the infected PC's resources without any regard for normal operating standards.

Although TrojanDownloader:Win32/Small.gen!I does set itself to launch with Windows, its file-downloading behavior doesn't leave any visible symptoms, by default. Malware experts also have been unable to identify any memory processes associated with TrojanDownloader:Win32/Small.gen!I, which could indicate that at least some variants of this Trojan are abusing memory-injecting strategies. Like other stealth-based Trojans, TrojanDownloader:Win32/Small.gen!I may only be detectable by anti-malware programs with active protection routines or features for scanning your system.

The Malware Problem with Returning Tendencies

Attacks by some variants of TrojanDownloader:Win32/Small.gen!I Trojans historically have included self-defensive functions that may prevent your anti-malware products from removing, albeit not identifying this threat. You can avoid TrojanDownloader:Win32/Small.gen!I restoring itself by using additional, standard anti-malware procedures designed to support your anti-malware tools while they scan your PC. These procedures may include basic Windows features, such as Safe Mode, restarting your PC in a secondary OS or booting your PC from a removable USB device. Malware experts particularly encourage using all file-scanning options available to identify both TrojanDownloader:Win32/Small.gen!I and other threats that TrojanDownloader:Win32/Small.gen!I may have installed.

TrojanDownloader:Win32/Small.gen!I is part of a family that's specific to the Windows operating system. Despite that specialization, threats all but identical to TrojanDownloader:Win32/Small.gen!I have been seen in most Unix-based OSes, as well as Mac's OS X. You can curtail the majority of these incidents through appropriate web-browsing safeguards. In other cases, TrojanDownloader:Win32/Small.gen!I continues to provide reasons for scanning your PC periodically for significant security hazards that don't extend the courtesy of loading any symptoms.
