once I was also having the same problem while updating the software, and after searching the internet I came to know about the script that I have mentioned below, and would suggest you to run it.
Code:
begin
SetAVZPMStatus(True);
SetAVZGuardStatus(True);
SearchRootkit(true, true);
QuarantineFile('C:\Windows\Jlasea.exe','');
QuarantineFile('C:\Users\Joreti\AppData\Local\Temp\Jjf.exe','');
StopService('KMService');
DeleteService('KMService');
QuarantineFile('C:\Windows\system32\srvany.exe','');
DeleteFile('C:\Windows\system32\srvany.exe');
DeleteFile('C:\Users\Joreti\AppData\Local\Temp\Jjf.exe');
DeleteFile('C:\Windows\Jlasea.exe');
ClearHostsFile;
BC_ImportDeletedList;
BC_ImportAll;
ExecuteSysClean;
BC_Activate;
RebootWindows(true);
after running the script you have to post the combofix log From your machine which actually located in c:\combofix.txt.
