First noticed that the ZA icon wasn't in the system tray. A virus scan (AVG free) identified 10 items it classified as trojan horse; all were ZoneLabs vsmon.exe. I let AVG remove all these items.
After this I found that my browsers (Firefox2 and IE7) couldn't access the Internet. No problem with email (Outlook) and utilities that connect to the Internet. Just the browsers.
Finally, in Windows task manager: zlclient.exe is running, but vsmon.exe flashes on for about half a second, disappears for two or three seconds, appears again for half a second, disappears, etc., etc.
I would be grateful for any guidance on what I should do now.
