PC works only on safe mode, not in normal mode

Whenever I try to startup in a normal mode, it always restarts. The windows log icon just appears then restarts again and again, until I boot to safe mode. (safe mode with networking also works)

I think my PC is infected
however, i cannot go on with the procedure in the sticky thread because it requires the Msconfig to be set for Normal Startup mode.

what should I do?

I've cleaned the registry through CCleaner and also tried system restore but nothing worked.

:cry

 

Welcome! to MajorGeeks.com!

Please follow the instructions in the below link and attach the requested logs when you finish these instructions.

• READ & RUN ME FIRST. Malware Removal Guide

• If something does not run, write down the info to explain to us later but keep on going.

• Do not assume that because one step does not work that they all will not.

Notes:

1. If you run into problems trying to run the READ & RUN ME or any of the scans in normal boot mode. You can run steps in safe boot mode but make sure you tell us what you did later when you post logs. See the below if you do not know how to boot in safe mode:
   
   • Starting your computer in Safe mode
2. If you have problems downloading on the problem PC, download the tools on another PC and burn to a CD. Then copy them to the problem PC. You will have to skip getting updates if (and only if) your internet connection does not work. Yes you could use a flash drive too but flash drives are writeable and infections can spread to them.
