Explorer.exe creating many internet connections to random ip addresses

I have a friend who received an email with a zip attachment about air line tickets.  I was able to scan the computer and remove the virus.  However now everytime he starts up his laptop, Explorer.exe runs at a hight cpu percent and there are over 100 connections to random IP addresses.  Their status is either established, time_wait, or Close_wait.  

His system is running windows 7 home premium.

On occasion, after arount 15minutes, the process will end, and system idle will be over 90%.  On most occasions it never ends.

I have disabled all startup entries, processes not microsoft, and have disabled hidden startup's with sysinternals autoruns program.

When I boot to safemode, the same thing happens.  

Not sure what to do next.  I have used Kaspersky's cd scanner too.  No virus was detected.

What did you use to remove the virus?  I would definitely run a full scan with Malwarebytes.

If the problem happened recently (1-2 days), restore your PC to an earlier time by booting up in safe mode with command prompt and typing rstrui.exe to restore.

Scan with:

(1) Malwarebytes Antimalware (free).

(2) TDSSKiller (free).

(3) Malwarebytes AntiRootkit (Beta) (free).

I scanned with malwarebytes twice.  1st scanned resulted in 33 registry entries, 8 values, 15 folders, and 57 files, detected with items such as funmoods, whitesmoke, visual bee.  

2nd scan had 1 detection from vid-saver.

Prior to scanning, I went to add remove programs and uninstalled several free programs and toolbar addons.

I will try system restore.  I will have to remove those programs again, but I will check for internet connections prior to removing the programs.

By the way, there are 4 instances of explorer.exe running, each using 20 to 40 % of cpu.  And the dll's are for various programs.

Ive been monitoring explorer.exe with process explorer from sysinternals.  Every 10 minutes or so, all the dll's will end at the same time, then startup again after a few seconds.
