Hello!
There are quite a few infections here. I am not sure did this cause all your problems...but I could give my left hand it will be somehow better after the fix.
OK, I guess the first part of the fix is following, please deeply concentrate.
You may want to print out these instructions for reference, since you will have to restart your computer during the fix.
Please download FixWareout from one of these sites:

http://swandog46.geekstogo.com/Fixwareout.exe
Save it to your desktop and run it. Click Next, then Install, then make sure "Run fixit" is checked and click Finish. The fix will begin; follow the prompts. You will be asked to reboot your computer; please do so. Your system may take longer than usual to load; this is normal.
When your system reboots, follow the prompts. Afterwards, HijackThis will launch. Please click Scan, and check the following items:
C:\PROGRA~1\Crawler\Toolbar\CMail.exe

Fix selected. Close HijackThis, and click OK to proceed.
At the end of the fix, you may need to restart your computer again.
