Thanks for your response.
I already tried updating the keyboard's driver but it's up to date.
Here are the .sys files.
Regarding with the programs I used, it's MBAM and Avira. I just scanned today with MBAM and there are 5 viruses found.
C:\Windows\System32\8BD793\cnvpe.fne - worm. autorun
C:\Windows\System32\8BD793\dp1.fne - worm. autorun
C:\Windows\System32\8BD793\HtmlView.fne - hacktool.patcher
C:\Windows\System32\8BD793\internet.fne - hacktool.patcher
C:\Windows\System32\8BD793\irnln.fnr - trojan.agent
During the scan, I can type with letters but when I have pressed the shift key, the problem came back. Moreover, the CD-rom suddenly opened by itself and it reads once in a while even though there's no CD in it.
Anyway, I restarted the system but the problem is still there. I'm currently scanning the system with Avira. I also have Super Anti Spyware but it won't open for unknown reasons.
