Please note that entries highlighted always require futher investigation.
However, this one definitely raises concern:
O4 - HKCU..\Run: [startkey] C:\WINDOWS\system32\server.exe
A web search indicates that the process may be legitimate, or may be malicious, so the question is, do you have Novell’s server suite installed on your computer?

In the meantime, I suggest a scan with Ewido anti-malware, which has a free scanner and will remove any malware found:
