I use the latest free version of CCleaner, and every time I try to use it, stuck at 26%, and I have to manually restart PC with the button on case.
First time was a file called unidrv.dll, so after I excluded that file, but now stuck with a file called banish.exe. I can try to also exclude it, but I suppose there is something wrong.
Both files are in Appdata/Local/Temp
With older version of CCleaner, I hadn't this problem. I formatted PC 2 weeks ago. Primary HD is a SSD Samsung Evo 850, and I checked it a few times, and it works perfectly.
I agree with Derek. All I can find on banish.exe are reports of it being possible malware.
You may be able to exclude those files, but you really need to find out where banish.exe came from, and if it's Malware, is the program it belongs to still active somewhere on your computer.
Do you know where it came from?
If you don't, I would suggest paying a visit to one of the reputable Malware Removal Forums listed in rule #10 here ...
Some forms of malware are very tenacious and I suspect this is why CCleaner is having a difficult time trying to delete the file.
Uhm...I haven't any problems with unidrv.dll. That page you linked, seems to be related to some error messages and others. I haven't messages. Simply CCleaner wanto to delete it, but fail.
About banish.exe, I tried to scan it with my antivirus (BitDefender 2014) and Malvarebytes Antimalware, and seems to not be a threat.
EDIT: Running CCLeaner with PC in safe mode, works.
It's your choice what you do Siegfried, but files like banish.exe don't just appear by themselves and it's not part of Windows.
It would have been part of something else and if you aren't aware as to what, then even though you've deleted banish.exe, that something else could still be on your computer. Researching that file doesn't bring up a great deal but most of what does come up relates to it being very suspect.
Take a chance, or get your computer checked out properly. Up to you.
