You might want to copy and paste these instructions into a notepad file. Then you can have the file open in safe mode, so you can follow the instructions easier.

We need to temporarily disable Spybot search & Destroy`s tea time, as it may interfere with any fix we are trying to run.

Disable Spybot's TeaTimer. This is a two step process.
First:
- Right click Spybot in the System Tray (looks like a calendar with a padlock symbol)
- Choose Exit Spybot S&D Resident
Second:
- Open Spybot S&D
- Click Mode, check Advanced Mode
- Go To Left Panel, Click Tools, then also in left panel, click Resident
- If your firewall raises a question, say OK
- Uncheck the box labeled Resident Tea-Timer and OK any prompts.
- Use File, Exit to terminate Spybot
- Reboot your machine for the changes to take effect.

Boot into safe mode, under your normal user name(NOT THE ADMINISTRATOR ACCOUNT). See how HERE.

In Windows Explorer, turn on "Show all files and folders, including hidden and system". See how HERE.

Delete all files in AVG Antispyware quarantine. Tell your friend to stop downloading keygens as they are often infected with malware, as is the case in his AVG Antispyware log.

Open your task manager, by holding down the ctrl and alt keys and pressing the delete key.

Click on the processes tab and end process for(if there).

PowerReg Scheduler V3.exe

Close task manager.

Run HJT with no other programmes open(except notepad). Click the scan button. Have HJT fix the following, by placing a tick in the little box next to(if there).

O4 - Startup: PowerReg Scheduler V3.exe

Click on the fix checked button.

Close HJT.

Locate and delete the following bold files and/or directories(if there).

PowerReg Scheduler V3.exe<Search the system for this file and delete all instances found.

Reboot into normal mode and rehide your protected OS files.

Post a fresh HJT log and let me know if the system is still having problems.

That HJT log is clean.

Turn off system restore.(XP/ME only) See how HERE.

Now, turn system restore back on. This will have deleted all your old restore points and any nasties that are in them. It will also have created a new, clean restore point.

If you have any further virus/spyware problems, please post in this thread.
