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.

Trojan.Spy.Banker.Gen is a generic detection label for banker Trojans that specialize in stealing financial information (such as login information for bank accounts). Trojan.Spy.Banker.Gen is also particularly-associated with Trojans that steal Brazil-specific information and take additional actions to hamper the infected computer's security. Although Trojan.Spy.Banker.Gen is an incredibly-invasive threat to your PC, symptoms of Trojan.Spy.Banker.Gen infection are minimal to the point of being close to invisible. SpywareRemove.com malware researchers, therefore, recommend that you use good anti-malware software to detect and remove Trojan.Spy.Banker.Gen from your PC. Trojan.Spy.Banker.Gen is sometimes distributed in the form of fake e-card file, and for this reason, you should be cautious about opening .exe files that claim to be virtual greeting cards.

Why It's Not an Easy Trick to Detect Trojan.Spy.Banker.Gen with Your Own Eyes

Trojan.Spy.Banker.Gen has been noted to use a number of tricks to infiltrate a PC and remain undetected. The foremost 'gotcha' that Trojan.Spy.Banker.Gen uses is to package itself with the disguise of a greeting card program; this program can often be detected by looking for the phrase 'cartão' (Brazilian for 'card') in the file name. The file extension may vary, although Trojan.Spy.Banker.Gen has been seen using .exe, .scr and .pif. The file itself must be manually-launched before Trojan.Spy.Banker.Gen can infect your PC unless another PC threat (such as a dropper Trojan) is involved.

Once you install Trojan.Spy.Banker.Gen, Trojan.Spy.Banker.Gen will create a process that may imitate a normal Windows file like 'explorer.exe.' Although Trojan.Spy.Banker.Gen will launch itself whenever Windows starts since Trojan.Spy.Banker.Gen uses the same name as a process that does that anyway, detecting Trojan.Spy.Banker.Gen's aberrant file process can be difficult. In most cases, SpywareRemove.com malware analysts recommend that you detect Trojan.Spy.Banker.Gen by using a good anti-malware program to do the job, and remove Trojan.Spy.Banker.Gen with the same program.

Trojan.Spy.Banker.Gen and Its Lethally-Quiet Banking Backstab

Trojan.Spy.Banker.Gen (also detected as PWS-Banker, Infostealer.Bancos and TrojanSpy:Win32/Banker.GV) is somewhat-noteworthy for its preference on stealing information from the Bank of Brazil. However, SpywareRemove.com malware experts caution that lesser-known variants of Trojan.Spy.Banker.Gen may also be used to steal financial information from other institutions. Trojan.Spy.Banker.Gen's default behavior include:

Recording private information when your web browser loads the Bank of Brazil and similar types of financial sites. This information is then sent to criminals who can use it to break into your bank account or make fraudulent charges.
Deleting security-related files (including bank-related security files like GbPlugin that can protect their customers' information).
Running itself automatically in the form of a background memory process. You may be able to detect this Trojan.Spy.Banker.Gen process from Task Manager, although Trojan.Spy.Banker.Gen's process may use a normal Windows file name like explorer.exe. Checking for memory usage differences and unusual process duplicates can help to identify a Trojan.Spy.Banker.Gen process.
