I thought that you already had the Kerio firewall?
Please read the following carefully. Read it a couple of times if necessary and if there's anything that you don't understand, please ask.
It might be wise to print it out.
You will need to download the following and burn them to CD:
[highlight]
Internet Explorer 6 SP1[/highlight]
[highlight]
AVG Free Antivirus[/highlight]
[highlight]
Kerio Personal Firewall 215[/highlight]
[highlight]
Spybot S&D[/highlight]
[highlight]
Ad-Aware[/highlight]
[highlight]
A˛Free anti trojan[/highlight]
[highlight]
SpywareBlaster[/highlight]
I'm assuming that you're familiar with restoring your system from your restore disks so I'll let you get on with that with the simple proviso that you disconnect the lead to your modem so that the computer cannot connect to the internet. Also unplug any network cables etc so that the computer cannot connect to any other computer.
In other words, fully isolate your computer at this point.
Once the restore has completed successfully, take a look at the Control Panel>Add/Remove Programs applet and uninstall anything that you don't need.
Carry out the following in order:
Install Internet Explorer 6
Install Kerio
Install Spybot
Install Ad-Aware
Install AVG
Install A˛Free
Install SpywareBlaster
Do not install anything else at this stage.
Set up your internet connection
Reconnect your modem lead, connect to Windows Update via the Start Menu icon and install critical updates only.
Update AVG, Spybot, Ad-Aware, A˛ Free and SpywareBlaster.
Do not update Kerio. Do not visit any other sites. Do not use email.
Once all are updated, disconnect from the internet and scan the computer with, in this order:
AVG
A˛Free
Spybot
Ad-Aware
Fix anything that's found but make a note of what is found first.
Now install your usual programs such as office suite etc, scanning after each installation. Install your printer drivers etc. This is a bind but we need to know if any of the software that you currently have is infected in any way.
I've got a nice dose of 'flu, so if anyone spots anything glaringly wrong here, please feel free to amend.
