Several problems - No wireless connection etc

Hi all,

I recently started having several problems with my Vaio, running Vista Business, SP2:

-Log in takes 3-5 minutes. The dependency service or group failed to start
-No wireless connection. The Windows wireless service is not running. Connection status: unknown The dependency service or group failed to start.
-DHCP client says it is "starting".
-System event notification service (SENS) is "starting"
-Problem report tells shows service hang report for both DHCP and SENS.
-Event Log is unavailable. Verify that the service is running.
-Task Scheduler service is not available. Verify that the service is running.
-Windows update screen very slow, view update history only gets me a blank screen...

I've tried system restore but when completed, Kaspersky suddenly warned about and deleted a trojan - problems start again.
No luck with SFC /Scannow (yields no errors) and nets winsock reset catalog did nothing.

(Edit: kaspersky now finds nothing)

Any other good ideas out there?
thx
noob

Run your anti virus and download and scan with malwarebytes.

Richard, thx for your response. Have scanned with Kaspersky several times. Also tried malwarebytes but again nothing found. I'm stuck.

Try in safe mode, what is the result?

If not sucessful, try clean boot
