Couple of thoughts.
I have heard of folk having "trouble" with the latest version of FF, v 2.0.0.7. Me ... I'm sticking with 2.0.0.6 for the time being.
Have you tried removing/uninstalling FF completely from your system then downloading/re-installing a fresh copy of v 2.0.0.6? Maybe this will help.
If not, and you want to investigate possible malware infections, you should do this systematically. Although the above suggestions are all good the approach is a little "scattergun".
At this point, if you are still having trouble, try this procedure to start you off ....
Run some first line (free) removal programs. These four ...
1. Superantispyware >

2. AVG Anti Spyware >

3. TrojanHunter >

Download each, update them to the latest definitions, and have them run full scans on your entire systems on their default settings.
Let them fix whatever they find.
4. ComboFix >
http://download.bleepingcomputer.com...a/ComboFix.exe
Double click combofix.exe & follow the prompts.
Note >> Do not mouseclick combofix's window while it's running. That may cause it to stall.
When finished, it will produce a log for you. The report is called
ComboFix.txt. Make sure you save this log.
Next download Trend Micro HijackThis 2.0.2 here ……
http://www.trendsecure.com/portal/en...HJTInstall.exe
- Save HJTInstall.exe to your desktop.
- Doubleclick on the HJTInstall.exe icon on your desktop.
- By default it will install to C:\Program Files\Trend Micro\HijackThis .
- Click on Install.
- It will create a HijackThis icon on the desktop.
- Once installed, it will launch Hijackthis.
- Click on the Do a system scan and save a logfile button. It will scan and the log should open in notepad.
- Click on "Edit > Select All" then click on "Edit > Copy" and Paste the entire contents of the log (no attachments) into your next post.
DO NOT use the
”AnalyseThis” button. Its findings are dangerous if misinterpreted.
DO NOT have Hijackthis fix anything yet. Most of what HJT lists will be harmless or even required by your Operating System.
Post the logs from ComboFix and HiJackThis in your next reply along AND an update on how the computer is operating now.
