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:	16

VirusFighter (also known as VIRUSFighter Pro, VIRUSFighter or Virus Fighter) is a rogue anti-virus program that displays fake virus alerts and other forms of fraudulent system information instead of providing actual anti-virus functions. SpywareRemove.com malware research team has found that VirusFighter has been distributed throughout several websites that claim that VirusFighter is a genuine AV product; these sites may also attempt to install VirusFighter or a related type of PC threat (such as a dropper Trojan) by using browser exploits. If you find VirusFighter on your PC, don't attempt to remove VirusFighter by manual methods, since VirusFighter has been confirmed to survive standard deletion techniques. However, a competent anti-malware product can remove VirusFighter and all of its hidden components without any danger for your PC.

VirusFighter – Fighting for Your Attention with Trojan Assistance

In most cases, a VirusFighter infection will only occur after you've visited a scamware website or been infected by a Trojan that specializes in installing rogue AV programs like VirusFighter. Some websites that SpywareRemove.com malware analysts have confirmed to distribute VirusFighter (as well as other types of PC threats such as TR/Dropper.FakeAlert) include qweas.com, soft82.com and subdomains of smartcode.com. Avoiding all of these sites is critical to protecting your PC from VirusFighter since even a brief visit may result in drive-by-download attacks that install VirusFighter without your permission.

Other means of preventing VirusFighter-related attacks against your PC include:

Keeping your web browser up-to-date to reduce security flaws (although zero-day security holes are still possible).
Using an unpopular web browser that isn't targeted by common exploits and attacks.
Using strong security settings for your web browser (such as disabling scripts for strange websites).
Keeping an up-to-date anti-malware program to detect VirusFighter-related attacks as they occur.

What Makes VirusFighter More of a Fight for Your Own Computer's Survival

Once VirusFighter is installed, VirusFighter will engage in some of the standard attacks that rogue AV products are known to use, such as creating fake infection alerts and inaccurate system scans. VirusFighter and related PC threats may also attempt to redirect your web browser to harmful web sites or block your security software. Because VirusFighter launches itself as a background process even if VirusFighter appears to be removed from your installed programs list, SpywareRemove.com malware researchers recommend that you use a suitable anti-malware product to remove VirusFighter from your computer.

Any system scan to remove VirusFighter should also be complete enough to detect and remove related PC threats such as dropper Trojans, since there is a high probability of other forms of hostile software also being present. However, as long as you do this promptly and avoid any attempt to purchase VirusFighter, your computer should be unharmed by a temporary VirusFighter infection in the long term.
