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.

Troj/Bredo-ABB or Gen:Variant.Barys.7136 is a recently-detected Trojan that's distributed by fraudulent e-mail messages that claim to be from Groupon – a discount website that e-mails its bargains straight to the mailboxes of its members. Unlike normal Groupon e-mails, Troj/Bredo-ABB e-mails include a zipped file attachment that infects your PC with Troj/Bredo-ABB. The recently-identified nature of Troj/Bredo-ABB has left its payload and overall capabilities uninspected as of the time of this writing, but SpywareRemove.com malware experts have noted that similarly-distributed Trojans often include downloading or backdoor capabilities that can install other PC threats or violate the security of your computer. Ideally, Troj/Bredo-ABB's e-mails should be deleted as soon as they're seen, although anti-malware applications should be utilized to remove Troj/Bredo-ABB in cases of definite infection.

Troj/Bredo-ABB: the Discount Offer on a Trojan

Troj/Bredo-ABB is an actively-distributed PC threat and should be considered a particular risk to PCs with outdated anti-malware software (or, of course, no anti-malware software at all). Similar but not as recently distributed members of Troj/Bredo-ABB's Bredo family include Troj/Bredo-VV, Troj/Bredo-QI, Troj/Bredo-RK and Troj/Bredo-ZT. Troj/Bredo-ABB's favorite distribution means is through fraudulent Groupon e-mails that are formatted to appear similar to official communications, complete with mentions of the Groupon Promise, a mobile app and an inclusion of the Groupon logo.

Details that differentiate Troj/Bredo-ABB's e-mails from the real things include typos on the current subject line ('Groupon dicount gifts') and, of course, a request that you download and view a ZIP file attachment to receive a discount coupon. Any attempt to access the supposed gift coupon that's being offered in these e-mails only will infect your computer with Troj/Bredo-ABB. Troj/Bredo-ABB, in its turn, has a high probability to install other forms of hostile software or attack your PC's security software/settings, and SpywareRemove.com malware experts recommend is immediate deletion via any available anti-malware product.

The ABCs of E-Mail Safety with Troj/Bredo-ABB

Since the real Groupon will never ask that you open a file attachment, SpywareRemove.com malware researchers note that this detail is an easy way to identify fraudulent Groupon messages, including Troj/Bredo-ABB's, which should be deleted on sight.

In case you need to open a file attachment from such a suspicious source, you should always scan the file prior to opening it, which some anti-malware programs will perform automatically. Anti-malware software should be able to detect the unzipped Trojan as Troj/Bredo-ABB, and some anti-malware programs may also detect the ZIP, itself, as Mal/BredoZp-B. However, since Troj/Bredo-ABB is a very new PC threat, anti-malware applications that are using old databases may be ill-equipped to identify or remove Troj/Bredo-ABB, and SpywareRemove.com malware researchers always advise that you maintain your security tools up-to-date with their most recent patches.
