[Skunkworks] viruses {m1h5i2y1t4h4.exe}

Hi Good people, I have some viruses that are preventing my collogues form accessing the internet. I have tried to install the following; Nod32, it cleaned some but still not able to clean this; {m1h5i2y1t4h4.exe} On trying to uninstall the Nod32 to install endpoint it gives an error message that processer does not allow this.... Does anyone there know a better antivirus that I can use to clean this; {m1h5i2y1t4h4.exe} Preferably a shareware. -- Regards, Robert.
