Update-critical.com

Update-critical.com is a malicious site that offers fake browser updates that actually are installers for a backdoor Trojan, Trojan.Win32.Generic!BT. Trojan.Win32.Generic!BT includes multiple components, such as up to eleven randomly-named memory processes and a variety of hidden files, as well capabilities for contacting malicious servers and launching itself automatically whenever Windows starts. Although Update-critical.com's payload is relatively identifiable after its installation (since Trojan.Win32.Generic!BT doesn't try to conceal all of its numerous memory processes), SpywareRemove.com malware researchers still recommend avoiding Update-critical.com infections in the first place, and removing Update-critical.com's Trojan, which is a high-level security threat, from your PC with dedicated anti-malware utilities ASAP.

Why It's Critical that You Skip an Update-critical.com Update

Fake updates are one of the easiest ways for a high-level PC threat to get onto your computer, but SpywareRemove.com malware experts are most familiar with such exploitative tactics using the disguise of fake Adobe Flash patches. Update-critical.com, rather than being a Flash update pop-up, is a dedicated website that detects your Web browser (from Internet Explorer, Chrome or Firefox) and then offers an update that's relevant to that brand of browser. The separate Web pages for each of these 'updates' are in varying levels of construction, but all attempt to look like legitimate download sources for browser patches. All of them also include some script-based content that prevents you from navigating away from Update-critical.com – by displaying a pop-up message every time you try to do so.

Installing Update-critical.com's apparent update, instead of upgrading your browser, infects your PC with a Trojan with backdoor functions, currently identified as Trojan.Win32.Generic!BT. Trojan.Win32.Generic!BT includes several techniques that would make its removal difficult – such as hiding some of its files and injecting its code into unrelated processes – as well as displaying multiple memory processes that are independent of all normal programs. While not too difficult to observe by eye, Trojan.Win32.Generic!BT is difficult to remove without dedicated anti-malware tools and poses the following dangers, in particular:

• Trojan.Win32.Generic!BT has some limited defenses against malware analysis environments and may attempt to disable itself when Trojan.Win32.Generic!BT is in the presence of any debugger software, sandbox utilities or similar programs.
• Trojan.Win32.Generic!BT can make contact with criminal-operated malware servers to receive instructions on other attacks to be made against your computer.
• Trojan.Win32.Generic!BT may install other malicious software automatically – in addition to the default components included with Trojan.Win32.Generic!BT.
• Trojan.Win32.Generic!BT may be used to steal private information, such as passwords, credit card numbers or e-mail addresses.

Saving Your PC from the Worst Browser Update to Date

As a harmful website, Update-critical.com can be defended against by all of the usual browser security features, strategies and relevant security software. SpywareRemove.com malware researchers especially highlight the usefulness of disabling scripts by default, which will allow you to navigate away from Update-critical.com's Web page in any case of being redirected to Update-critical.com by mistake. Secondary, a simple understanding of the dangers presented by fake updates, along with a steadfast avoidance of downloading software updates from any places other than their official websites, should prove to be an excellent safeguard against attacks like Update-critical.com's own and the drive-by-downloads of similar sites.

If you believe that Update-critical.com has infected your PC already, anti-malware software can be used to delete Update-critical.com's payload and all of its system changes safely. The defenses employed by Update-critical.com's Trojan, along with the sheer diversity of its components, make all normal uninstallation methods impractical, at best.
