Problem with laptop Acer

HELP! I have a problem with my laptop Acer EXTENSA 5635GT - Intel dual core 2.10ghz, 3gb RAM, Windows 7 OS.
The problem is that it suddenly became very slow. When I try to open any folder - it takes more time than normal. I can't do anything. Like the processor is 500mhz. I remeber my AVG showed a notification that she found Trojan horse in "odbc.exe". Is it something about it?! Also, there is a notification that my battery needs changing, but I don't use it.
I tried system restore, but there are no control points. I looked all over the laptop but it doesnt seem to be overheating. Please, help me

Welcome to Windows Seven Forums.

First, download Malwarebytes and run a full anti-virus scan in Safe Mode.

If you don't use the battery just remove it.

Have you checked to see whether System Restore is switched on?

I haven't checked if System Restore is switched on. How can I do that?

This will show you where to check,

System Protection - Turn On or Off

I checked - it is switched on for hard drive C: (where is my OS), and switched off for hard drive D:

That sounds right.

Are you saying windows couldn't find your restore points?

I agree with Seavixen, that you should run a full scan with Malwarebytes to be sure.

Alright, after that, let us know if it finds and removes anything.

We'll work on system restore after that.

Okay, completed full scan for 40 minutes and found 12 errors:
2 Trojan.Vundo and the rest are Adwares. All this is found in registry keys.

Did you have it remove all of them?

If not, remove all and run again to make sure you are clean.
