Can't seem to delete windows installer malware-trojan-gen

Viruses and worms
1

My full-screen applications started “losing focus” here lately and I scanned, finding a virus I couldn’t get rid of. I attempted to follow the directions to post and attach the correct files, but when I did the OTL scan it didn’t give me an “Extra” log. If there is anything else that is needed from me please let me know! I will do the aswMBR scan and log now.

Here is the aswMBR log

but when I did the OTL scan it didn't give me an "Extra" log
it only happens at first run....run it before? anyway that log is not important and normally not needed

malware removers are notified…be patient

OBS: and malwarebytes was not updated when you run it…
and it seems you have a Siref rootkit…
