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.

With Christmas seeming to start earlier than usual each year, spammers are starting their own Christmas-based malware campaigns with just as much alacrity – as evidenced in the fake greeting cards that distribute W32/AutoRun.BBC!worm. While W32/AutoRun.BBC!worm's e-mail package uses Flash animations to hide its real purpose as a malware carrier, any attempt to open its attached file will infect your computer with the Windows-compatible worm W32/AutoRun.BBC!worm, which may further its distribution through local networks and/or removable drives. SpywareRemove.com malware experts recommend that you do everything that's necessary to prevent a W32/AutoRun.BBC!worm infection from spreading and then use anti-malware products as required to remove W32/AutoRun.BBC!worm completely from your PC.

When Santa's Presents are Full of Worms

Exploiting the eagerness of PC users, like everyone else, for embracing the upcoming holidays, the criminals behind W32/AutoRun.BBC!worm's distribution use Flash e-mail messages as the major means of W32/AutoRun.BBC!worm's conveyance. These e-mails include Flash content crafted to look like seasonal greeting cards, along with a forged 'From' field that makes the e-mail look as though it's sent from a legitimate source. However, the holidays are likely to become not-so-merry if you open the e-mail's ZIP file, which SpywareRemove.com malware analysts have found to contain W32/AutoRun.BBC!worm.

Like any true worm, W32/AutoRun.BBC!worm can create copies of itself and distribute those copies to other PCs. SpywareRemove.com malware experts have found several potential infection vectors that W32/AutoRun.BBC!worm may use to distribute itself, such as:

P2P torrent networks; W32/AutoRun.BBC!worm may disguise itself as a different file and upload itself to be shared among P2P downloaders.
Removable drives; W32/AutoRun.BBC!worm may create copies of itself and use Autorun exploits to install a new copy of W32/AutoRun.BBC!worm on any computer that shares a rewritable CD, USB drive, etc.
Local networks; W32/AutoRun.BBC!worm can use similar techniques to the ones noted above to install itself on PCs that access a W32/AutoRun.BBC!worm-infected PC via networks. Beyond accessing the computer, no additional action on the part of the victim is required.
Locally-run websites that use Microsoft's IIS also may have some of their web page content replaced with malicious files that promote W32/AutoRun.BBC!worm (usually by disguising the worm as a download link to a security update).

SpywareRemove.com malware researchers also consider it likely that W32/AutoRun.BBC!worm will abuse an infected PC's resources, such as RAM, to spam copies of itself via e-mail, IM bots and other social networking-based methods. This can have the secondary effect of harming your PC's performance and cause overall instability in your OS.
