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.

Win32/Olmarik.TDL4 is a rootkit that's associated with other PC threats, general performance issues, the appearance of pop-ups and browser redirect attacks. Since Win32/Olmarik.TDL4 will rarely attack your PC by itself, any possible Win32/Olmarik.TDL4 infection should be dealt with via scans from anti-malware software that can also detect additional PC threats such as backdoor Trojans and Trojan droppers. Since Win32/Olmarik.TDL4, like most types of rootkits, has been noted to be very difficult to remove, SpywareRemove.com malware researchers discourage attempted removal of Win32/Olmarik.TDL4 without using Safe Mode, disabling System Restore and using other standard forms of anti-malware strategies to insure that your security software can completely-delete all components of Win32/Olmarik.TDL4.

Win32/Olmarik.TDL4 – At the Root of a Swarm of Issues

Despite its 32-bit-specific label, Win32/Olmarik.TDL4 is capable of attacking most versions of Windows, including Windows 7 in both 32-bit and 64-bit formats. Obvious symptoms of a Win32/Olmarik.TDL4 attack may be as minor as alerts from your anti-malware programs, although many Win32/Olmarik.TDL4 infections have also been noted for displaying, directly or indirectly, the following characteristics:

Pop-up windows that show advertisements or fake infection warnings.
Web browser redirects to hostile websites. Redirects often occur after attempted access to a search engine site.
Poor system performance, including slow responsiveness and arbitrary system reboots.
Random deletion of files on your hard drive (although critical system files are typically-exempt).

SpywareRemove.com malware experts have found that Win32/Olmarik.TDL4's presence is especially-likely to coincide with attempts to market rogue anti-malware programs and other types of scamware via pop-ups and redirects. However, other dangers, such as the potential presence of spyware, shouldn't be excluded from the realm of possibility. Unless immediately-caught, Win32/Olmarik.TDL4 will almost always be found alongside other PC threats besides itself.

How to Keep Win32/Olmarik.TDL4 from Coming Back

Due to its status as a rootkit, Win32/Olmarik.TDL4 has been known to avoid automatic deletion by system scans that lack additional safety measures. Removing Win32/Olmarik.TDL4 may require that you update your anti-malware software so that all of its components can be accurately-identified, especially if your threat databases are older than November of 2011 (when Win32/Olmarik.TDL4's attacks were recorded en mass). SpywareRemove.com malware analysts also suggest the following methods to make sure that deleting Win32/Olmarik.TDL4 goes off without a hitch:

Disabling System Restore until you're certain that you've deleted Win32/Olmarik.TDL4; this will prevent Win32/Olmarik.TDL4 and related rootkits from using your System Restore files to back up themselves.
Using Safe Mode as the preferred OS environment to scan your PC. Scans outside of Safe Mode may detect Win32/Olmarik.TDL4, but your chances of successfully-removing a rootkit outside of Safe Mode can be reduced due to the possible presence of active PC threats.
Using 'full' scan options for your anti-malware software, particularly options that allow you to scan your boot sector.
