Now do the following:
- Under Ad-aware 6 > Settings (Gear at the top) > Tweaks > Scanning Engine:
check: "Unload recognized processes during scanning."

Check: "Let Windows remove files in use after reboot."

- Check option "Activate In-Depth Scan"
- Press "Select drives\folders to scan"
- Select the active partition which is usually C:
Now press "Next" to let Ad-aware scan your drives...
It will find a number of "bad" files and registry keys.
Right-click in that pane and choose "select all"
Now press "Next" again.
It will ask you whether you'd like to remove all checked items. Click OK.
Finally, close Ad-Aware, and reboot.

Then:
Download 'Hijack This!'. http://www.computercops.biz/downloads-file-328.html
Unzip (extract) it to a folder of its own.Like c:\HJT\hijackthis.exe , Then Doubleclick HijackThis.exe (in the new folder), and hit "Scan".
When the scan is finished, the "Scan" button will change into a "Save Log" button.
Press that, then Ctrl-A to Select All, and copy its contents here. for hijackthis,most of what it lists will be harmless or even essential, don't fix anything yet.

Thanks so much for the advice! I may have some problems with the process, because I don't have a mouse, but hopefully I will be able to get by with a keyboard.

Ok, I reinstalled Norton Antivirus, and I have a virus called backdoor.sdbot. I've tried to delete it but it says it cannot be deleted. I went into the registry and deleted the strings that had to do with it also, but no luck. Does anyone have suggestions?

Symantic suggestion .

For me to look at ,
run hijackthis and post a hijack log

Thanks for the link! I got rid of the virus (I think), and the mouse has returned, but unfortunately the colors and the resolution are still off. I still can't change the settings also. Would hijackthis help with this problem?

not likely ,right clcik on mycomputer ,choose properties,go to device manager ,is there any yello or red ! marks ,check + by display adapters what does it say for your video card ,does it say windows default or does it give the name of your video card !!

When I click on the + next to display adapters, it says "Xpert 99/Xpert 2000," which I assume is the video card? Is this a good or a bad thing?

Good thing ,try right clicking on the desktop and hit properties .then along the top go to SETTINGS and change the screen resolution to 800x600 and color quality to high 16

That was the first thing I tried when this problem occured, but when I restart the computer, the settings don't change. It's very strange. I'm thinking that maybe something is wrong with the registry or something?
