How can I be sure if I am still infected with "Win32/Small.CA" virus".

OK all 3 of my PCs successfully ran ESET with the resultant message of: "No threats found".

What next?

Am I clean? e.g. I'm now worried about my archives. I have two 1GB external hard drives. Should I run Eset again with them switched on?

Should I re-run any other scans to make sure I am clean? Is it time to change all my passwords?

P.S. May I re-install Google Chrome now?

Great. Meanwhile what do I do about installing all the Microsoft patches?

Hi

OK... so I have set the 'Windows Update' service to 'Startup type' of 'Manual'.
The status right now says 'Started'


Meanwhile my ESET scan of my backup/archive external hard disk found something nasty.

E:\ALEC09\Backup Set 2012-09-26 224116\Backup Files 2012-09-26 224116\Backup files 13.zip Win32/OpenCandy application deleted - quarantined

I have now deleted the whole of that backup "Backup Set 2012-09-26 224116" in case it has anything else nasty it.

Btw, did I mentionthat ESET also had (previously) put this file into quarantine:
C:\users\Alec\Downloads\MyPhoneExplorer_Setup_1_1.8.2.exe

Fwiw, I have now deleted everything in my Downloads directory too.

Immediately after rebooting, there is a suspiciously long pause during which time the MSE icon on the task bar (bottom right of screen) has gone bright red with white "X" on it, which I found worrying. After about 1-2 minutes of very little happening and the task manager also reporting very little processor use, the widgets on my desktop that I have (that report local weather and processor temperature) finally appear and simultaneously the red icon goes green.

So I just uninstalled MSE and immediately re-installed MSE without rebooting.

"Solve PC issues:" on the taskbar is now moaning about
A) Windows Defender needing to check for updates.
When I click to see what's going on it, sure enough Window Defender appears to be half way through a very slow download with a status of "Searching"
What is Windows Defender? Is it part of Windows Security Essentials?
Because if not surely I should only have one antivirus application running at a time.
B) Microsoft Security Essentials is also taking a very long time to install the latest virus and spyware definitions from Microsoft. It too says "Searching..." as it has done for about 10 minutes.

===> Update:
BLOODY H*** !
After about 15 minutes I went into task manager and saw that TrustedInstaller was back hogging 25% of the processor. So I stopped it. Put it back to Manual and re-started it. Immediately I stopped it, both Windows Defender and MSE started downloading their virus and spyware definitions. WTF?
However Windows Defender then said a problem cause this program's service to stop. I tried re-starting it but by clicking on the "Start Now" button provided, but not happend.
So after MSE finished downloading its definitions I got it to run a quick scan.

==> Update
Okay I have now rebooted and the MSE icon goes green straight away (success!) and fwiw, the desktop widgets come up immedately too. But bloody h*** that TrustedInstaller.exe is back hogging 25% of the CPU.

Do we think TrustedInstaller has become corrupted? How do I fix this?
