If you see Computerhelper.site Security Help Page alerts then it is possible that your computer is infected with a Trojan that displays these types of alerts and other unwanted content. These types of alerts are commonly displayed by web sites and are gone once you shut down the browser. There have been some recent Trojans, though, that modify the legitimate C:\Windows\System32\dnsapi.dll Windows file in order to show you these types of alerts, advertisements, and to open unwanted web pages. These alerts are designed to scare you into thinking that your computer is infected so that you will call the number listed in the fake security alert. Once you call the number, the salesperson will try to convince you that your computer has a problem and that you should purchase a support contract to fix it. This is a complete scam and you should not purchase anything from numbers listed in alerts similar to the Computerhelper.site one shown below.
When infected with this DNSPatching Trojan, you will be constantly shown pages that display alerts like the Computerhelper.site ones shown above. These alerts are designed to trick you into calling the listed numbers in order to receive help. The reality is that the salesperson will say anything to trick you into purchasing a support contract.
Multiple settings on your browser and computer may not be properly configured which may result in poor internet browsing performance, excessive advertisements, and a slow loading computer, especially at startup. This could be because of outdated antivirus software creating other security vulnerabilities that could expose personal information (including photos, passwords, credit card details, etc.) You may also have system errors, registry problems, too many processes running, multiple programs launching at startup, or memory that is severely fragmented.

The phone numbers that are commonly associated with the Computerhelper.site alerts are 888-220-1478 and 888-544-1073. If you see these alerts, please do not call the listed numbers.
It is important to note that these alerts may be caused by adware that is bundled with and installed by free programs that did not adequately disclose that other software would be installed along with it. Therefore, it is important that you pay close attention to license agreements and installation screens when installing anything off of the Internet. If an installation screen offers you Custom or Advanced installation options, it is a good idea to select these as they will typically disclose what other 3rd party software will also be installed. Furthermore, If the license agreement or installation screens state that they are going to install a toolbar or other unwanted adware, it is advised that you immediately cancel the install and not use the free software.
Without a doubt, these alerts are a complete scam and are designed solely to scare you into calling the remote support number. If you see alerts coming from http://computerhelper.site, please ignore them and use this guide to remove the associated malware for free.

To do this, please download RKill to your desktop from the following link.
When at the download page, click on the Download Now button labeled iExplore.exe. When you are prompted where to save it, please save it on your desktop.
Once it is downloaded, double-click on the iExplore.exe icon in order to automatically attempt to stop any processes associated with Computerhelper.site Security Help Page Alert and other malware. Please be patient while the program looks for various malware programs and ends them. When it has finished, the black window will automatically close and a log file will open.
