Threat Metric
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.

Boot.Cidex (unrelated to Cridex, a multi-purpose worm) is a boot-sector rootkit, also known as a bootkit, that compromises your PC's security for criminal purposes, which usually include the installing of other threats or stealing personal information. As the latest variant of Boot.Cidox, Boot.Cidex may be difficult to detect or uninstall without the latest updates for your anti-malware software, and removing Boot.Cidex by any manual method is (as usual for rootkits) an extremely arduous procedure. Symptoms that you watch for while suspecting that you need to delete Boot.Cidex rootkits include substantial system lag and the creation unusual memory processes.
What Happens to Your PC After the Toe of Boot.Cidex Slams Home
Boot.Cidex is a rootkit that may infect components of your PC prior even to the loading of your operating system, which makes Boot.Cidex difficult to notice, isolate or remove. This behavior also has been seen throughout other bootkits like KINS or the famous Mebromi, and Boot.Cidex, itself, is part of a long line of updates to the Boot.Cidox family of similar PC threats. Boot.Cidex's overall threat profile is similar to that of a backdoor Trojan, with attacks against the security features and programs of the affected PC being the norm. Criminals may use the vulnerabilities created by Boot.Cidex to install new unsafe software, change your settings, control your input or steal private information.
Boot.Cidex is especially known for creating duplicate Explorer.exe memory processes, which Boot.Cidex may use to launch different attacks or occupy your PC's resources. Extreme cases of this problem may cause computers, particularly those with limited resources, to malfunction and crash. Malware experts find it easiest to use the default Task Manager tool when it's necessary to detect these extra memory processes, since there only should be one explorer.exe (the executable file for the Windows folder and file manager) at any given time.
Giving Boot.Cidex the Firm Boot that It Deserves
Boot.Cidex and most other rootkits are designed to launch even in Safe Mode, which is a useful feature for less invasive types of threats than the average boot sector rootkit. Although malware experts continue to recommend using Safe Mode during anti-malware scans, the use of extra security procedures for making sure you've removed Boot.Cidex is barely less than mandatory. Considering booting your PC from a spare USB device or backup CD, and then launching into anti-malware scans that can find and delete Boot.Cidex.
Boot.Cidex may not always show the symptoms described above, but that doesn't mean that Boot.Cidex can't harm your PC. Boot.Cidex, as a high-level PC threat, may implement attacks that compromise security and privacy without showing major signs of which for tracking its misbehavior. Ideally, a powerful and updated anti-malware tool should be able to block Boot.Cidex before Boot.Cidex is installed, or, at least, remove Boot.Cidex afterward. Since Boot.Cidex is itself, an update to old Cidox bootkits, any use of updated security software particularly is appropriate.
