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.
