3 days ago while browsing the internet my connection ceased.  I ran a spyware and virus program and it found a Trojan:AdRotator.   After the trojan was removed i ran error expert.  According to both programs my computer is clean but i still cannot browse the internet or receive email in Outlook.   If i go to the command prompt i can run the ping exercise fine.  So, my modem seems to be interacting with my computer okay.    I just don't know what to do now.  

Please help.

Agreed, Winsock fix will usually fix it.

It will reset your hosts file, appropriate registry entries, etc.

Extremely useful after ripping out Norton which can sometimes cause the internet to go dead. Also works great after a virus removal like yours.

Could still be infected...

It would help if we could see what was going on with your computer. I suggest that you download, run, and post a HijackThis log from the link below.

NOTE: Do not fix anything with HJT at this point, upload the log to the link below and just post the link to it back here.

Yeah, rip out Norton/McAfee, they're junk. Install NOD32 Security Suite.

Install Firefox 2.0.0.9, Foxit Reader, Ccleaner (and then use it's automated tools to clean out the junk).

Rip out Adobe Reader (the new version is good, but FoxIt reader is far quicker). Rip out any bloatware you can find from the manufacturer, AOL, Dell Support, MusicMatch Jukebox, etc.

After that it should be running pretty briskly.

Not seeing anything malicious. Is this "slowness" a new problem, only since you were infected? I assume you've updated and run AVG AS and Spyware Doctor?

Poor performance isn't always Malware either. Here are some links with good info. on maximizing performance.

Slowdowns could be because of the programs you have installed, 2 antispyware running there.
In your running processes you have 2 antispyware programs AVG antispyware and Spyware Doctor, I would suggest just keeping one with a realtime protection, and leave one as an on-demand scanner if you must have both but only one running with realtime protection.
AVG Antispyware is good I would keep that.


You also have a process and a service running that belongs to Command Antivirus, or a malware protection belonging to Authentium's.
I would remove those unnecessary process and service that only takes up resources and slowdown. If you still have command antivirus then I would uninstall it via add/remove programs.

C:\Program Files\Common Files\Command Software\dvpapi.exe
O23 - Service: DvpApi (dvpapi) - Command Software Systems, Inc. - C:\Program Files\Common Files\Command Software\dvpapi.exe
 

To delete the service, you can go to Start Menu > Run > type

cmd

Press OK then type or copy and paste these commands onto the cmd screen pressing Enter after each line:

sc stop dvpapi
sc delete dvpapi


If problem persists, run combofix and upload the log for us to look at.
Download ComboFix to your Desktop, from either of these locations:
http://www.techsupportforum.com/sectools/sUBs/ComboFix.exe
http://download.bleepingcomputer.com/sUBs/ComboFix.exe

Double click "combofix.exe" and follow the prompts.
When finished, it shall produce a log for you.

Note: Do not mouseclick combofix's window while its running. That may cause it to stall
