Trojan Virus/missing File

We have a virus called troj_agent.bf but cannot seem to get rid after using spybot search & destroy, a2, housecall, adware. We have tried deleting the files they were in but comes up with missing file vsdata95.vxd. Can anyone advise what to do please.

 

Vsdata95 is a ZoneAlarm file.

Uninstall and reinstall ZA.

 

If WhitPhil post doesn't work then I suggest you do this:

Make sure you have the up-to-date versions of Spybot Ad-aware and HijackThis. All are free and available bellow.

Download Spybot, install and update. Then download Ad-aware, install, and update.

Spybot:
Go to Start > Programs >Spybot > Search & Destroy and choose Spybot S&D

Close ALL windows except Spybot S&D
Click the button to "Search for Updates" and download and install the Updates.
Next click the button "Check for Problems"
When Spybot is complete, it will be showing "RED" (RED) entries "BLACK" entries and "GREEN" (GREEN) entries in the window
Put a check mark beside the RED (RED) entries ONLY.
Choose "Fix Selected Problems" and allow Spybot to fix the RED (RED) entries.

Click Next and Ad-aware will scan your hard drive(s) with the options you have selected.

Save the log file when it asks and then click Finish

When finished, mark everything for removal and get rid of it. (Right-click the window and choose Select All from the drop down menu and click Next).


Download HijackThis from link in my signature. Save it to a permanent folder (I create a new folder in C:\ named HJT). Open and hit scan, then save log. Once it is saved it will open in notepad. Select all from the edit button, copy and paste the results here. Don't fix anything with it yet! Someone experienced with the logs will advise you.
