So I have this problem, everyday I have random pop ups of errors, for example: yesterday I had yrwb.exe - System Error (The program can't start because OpenCL.dll is missing.), today I have byowm.exe - System Error with same message as the previous. They really annoy me. They pop up every 5-10 minutes. I tried antivirus, searched for the files but I haven't found anything. I know that OpenCL.dll is required for video and graphics software, but I dont get what this "random name".exe files want. Can someone help me? Thanks.
That sounds like a virus, does not matter if you ran an anti-virus scan, unless you ran 2-3-4 different products and also did a scan using a rescue boot disk, you can still be infected. Don't touch this computer, burn an anti-virus rescue disk using another system, I use Avira Antivir for this, boot the computer using that disk, run the scan. Even if it does not find anything, I'd wipe the disk and install Windows clean on it.
