This virus is really harmful, if you want to use your antivirus it shut down your pc . if you want to install an antivirus it shut down your pc. if you want to install new OS it shut down your pc . you must login from safe mod and rename the runouce.exe by creating a new exe file and change it's security options . I had problem about 1 week because of this damn virus . god damn the programmer .

Runouce.exe is a malware,, if you want to stop run of this file, that you should have a search in windows\system32 folder, it’s a hidden file, many time of delete but it appear again and never delete...the solution is that, first you found the runouce.exe file, click right click to edit and open the file in notepad, when the file open in notepad all text that was copied in file delete all entries except first line, first line should have mention......then save the notepad file, runouce.exe were never attack to system originally ..It’s make a dummy file. Check it out. Computer will work properl
its a virus, and u can delete it using cmd.exe(if u knw how to use it. :p) and dnt forget abt regedit, go to registry and find out how much "runouce.exe" entries are there and then delete them.

VIRUS! it disable many application
Runouce.exe is the worst virus I have ever seen in my entire life. It affected me 3 days back when my brother downloaded some random thing from the internet which was packed by this virus "runounce.exe". It can block your internet connection, stop you from accessing anti-virus or anti-malware websites. Even if you try to install anti-virus software, it will not let it happen because it can understand and read names of the executables. I re-installed the Windows 3 times and and all of the times it returned. Luckilly I found a way to get rid of this virus and I will show how you can too Before starting let me summarize what "runounce.exe" can do 1-It can block your internet connection. 2-It can block your access to anti-virus websites. 3-It will not allow you to install anti-virus softwares. 4-It can spread in your whole computer and even replace your original windows files thus corrupting the operating system. 5-It uses your internet conenction to send email spam. In my case, along with runouce.exe there were two more viruses "net.exe" and "net1.exe". I think they are a part of the virus pack. After infecting the victim's computer, it make changes in the system reigstry and courrupts it. The 2nd thing it do is to spread in the system volume information of all the local disks you have on your system. So if you just format the C drive and re-install the Windows, runouce.exe will come again from other local drives.
its a virus an 2 got rid off it u ned too run in safe mod and delet it.

it affected my computer several times.first of all i updated kasparsky antivirus after that i removed the virus named email.worm-runouce.b again after 2 weeks it affected my computer again ......danger....
don't know but I suspect this virus ruining document encoding
The virus was injected into my RUNONCE.exe system file from a game trainer i downloaded for Call of Duty - Black Ops II. It infects every .exe file on your hard drive, even backup drives and external drives. It will spread to other PC's via an infected .EXE file. Reformat is the only option. Don't re-use any infected file.

My antivirus deletes it once and it comes back again. The only way to delete it is through Safe Mode.

It can be removed easily .. you have to take the ownership of folder first then you can remove it easily

Best practices for resolving runouce issues

The following programs have also been shown useful for a deeper analysis: ASecurity Task Manager examines the active runouce process on your computer and clearly tells you what it is doing. Malwarebytes' well-known Banti-malware tool tells you if the runouce.exe on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.

A clean and tidy computer is the key requirement for avoiding PC trouble. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
