It will block installation of Macromedia Flash on comcast net when XP Home is upgraded to XP Pro.
it was a spyware. Must delete it before you loss your data.
Virus software indicated it's a Trojan; it's time stamp (in System32 dir.) is identical to the time my computer began acting infected. It loaded a new 'badge' on my task bar, giving me a "Windows Security" error and lots of bogus warnings. It tried to have me load something called "System Protect"
It added an entry to hosts file, changed my DNS, and edited my prosy settings.
it is a spyware used by spyware protect and other things like it, it is used to make you think you have a virus put there by things like spyware protect 2009 to get you to buy it and spyware protect is a scam to get you to buy their 50 dollar program
It was autoremoved by AVG after attempting to load a banner add proclaiming itself as a malware-detector and remover. Forcing the program to quit and restoring the antiviral and anti-spyware suite as part of AVG Free detected and removed it before it could reload itself. IDd by AVG as 'Trojan Horse Downloader.Zlob_r.EX

this file is a VERY harmful trojan and it is essential that you try to remove it but it's very difficult to do so. Most often found when pc is infected with sysguard.exe
its spyware. remove it ASAP. run malware bytes.
It is scareware. It gives constant pop-ups that legitimate files are infected
Is used by the Browser Configuration Utility bundled with Gigabyte Motherboards. The utility is preinstalled and is an addon to your browser as a BHO. It's purpose is simply that when you type in a web search into your address bar it automatically uses Google search engine, and you cannot choose any other search engine. Very tricky, Gigabyte, users do like to be asked first. This is bloatware and should be uninstalled through Add or Remove Programs in your Control Panel. I was having problems with a faulting iehelper.dll in IE8 windows 7 64-bit and fixed this by uninstalling this utility.

Best practices for resolving IEHelper issues

A clean and tidy computer is the key requirement for avoiding problems with IEHelper. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the IEHelper.dll process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
