Tool:Win32/Hideproc.C is a new version of an old Trojan that's installed as one part of a larger infection for the purpose of concealing memory processes and other malicious components. Most Trojans like Tool:Win32/Hideproc.C will run without your permission as concealed memory processes and can be observed only indirectly through the side effects of their attacks. Since Tool:Win32/Hideproc.C may be part of a larger threat and even more malicious threat, you should immediately take action to delete Tool:Win32/Hideproc.C from your computer before serious damage occurs.

The many Tools of Tool:Win32/Hideproc.C's Malignant Trade

Tool:Win32/Hideproc.C is just a 2010 version of the Hideproc Trojan that was first noted in 2007. Since that time, different versions of Hideproc have appeared, including Tool:Win32/Hideproc.C as well as Trojan:Win32/Hideproc.F and Trojan:Win32/Startpage.RM.

Even if your security software can detect one of these threats, your PC may still be vulnerable to attacks by newer versions like Tool:Win32/Hideproc.C. Keeping your anti-malware programs completely updated is a vital step in protecting your PC from Tool:Win32/Hideproc.C. Avoiding initial infections can be done by keeping your browser up to date, disabling scripts from untrustworthy sources and avoiding suspicious files.

Some versions of Hideproc are installed as specific pieces of a larger infection for the purpose of hiding this infection. Tool:Win32/Hideproc.C may conceal, not only Tool:Win32/Hideproc.C's own memory processes, but also the memory processes of other malicious programs. When this is combined with a standard Trojan tactic of running automatically when Windows loads, this lets Tool:Win32/Hideproc.C and Tool:Win32/Hideproc.C's cohorts hide in plain sight while still being active at all times.

You can detect hidden memory processes by noting unusual system resource usage or by observing the other side effects of the attacks caused by Tool:Win32/Hideproc.C and similar Trojans.

Tool:Win32/Hideproc.C or threats related to Tool:Win32/Hideproc.C may also cause other problems:

  • Tool:Win32/Hideproc.C may block applications and even make it look like those applications are infected when they're completely fine.
  • Tool:Win32/Hideproc.C may create Trojans that imitate Windows errors to try to fool you into performing self-destructive actions. These Trojans can even imitate specific Windows functions like the Security Essentials Alert.
