Navigate to C:\PROGRA~1\MYWEBS~1\bar\2.bin\ once there locate the file. Start task manager (CTRL + ALT + Delete) locate mwsoemon.exe from the process tab, right click - End Process Tree, then delete the file in the folder you previously navigated to. If this doesn't work, right click the file and go to properties and edit your permission to full control in the security tab.
Spybot found it, and my computer lagged and crashed nonstop, cursor mania is the cause i say!
I also couldn't delete the folder using uninstall/remove programmes or windows explorer right click delete (access denied). However the solution is to kill this thing off at it's roots by going through REGEDIT via the RUN command in windows and removing the key. This will then clear the way for you to delete the My Web Search folder.
This file can make blue screen and send virus you need to delet this. Mye other computer got virus+ blue screen. Im warning you delet
It is malware, and it causes my sister's computer to use MyWebSearch as the search engine no matter what we do

I cannot get rid of this but it redirects u to different webpages from firefox and internet explorer it is extremely annoying and i hear sounds and popups playing on my computer and I cannot figure out where they are coming from!!! But i can't get rid of it
The best way to remove it is to end the process and then delete the files. If it dont let you then boot up in safe mode then remove them. Hope this helps.

Best practices for resolving mwsoemon issues

The following programs have also been shown useful for a deeper analysis: Security Task Manager examines the active mwsoemon process on your computer and clearly tells you what it is doing. Malwarebytes' well-known anti-malware tool tells you if the mwsoemon.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 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 repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
