PC gets very slow sometimes. Do i have a Rootkit ???

Hi,
my PC sometimes gets very slow, so I ran a Fullsystemscan with NIS 2010 and one with Malwarebytes, both scans resulted in no malware.
Here, in this community, I had read about sysprot and gmer, so I thought let's see what the result of those two programs (disabled NIS during the scans) is, because the issue is still there.
And gmer shows something what could be a rootkit, but I'm not sure.

Thank you for help!!!


Windows Vista Serv. Pack 2
Norton NIS 2010
Malewarebytes (free)
