Trojan horse Dropper.Delf.3.BE.

I'm using AVG Antivirus.
I've just installed the latest version and it has found a virus on my PC.
The previous version (which was ALWAYS kept uptodate had never reported this
virus.)
Before running anything downloaded, I always scanned it first and have
always been careful!

The problem is that I've run the file with the virus in a few times.
i do have the occasional problem with the PC, when it locks up or reboots.
This only happens 2 or 3 times a week.
I have no reason to suspect I have a virus otherwise.
(And I don't have a million pop ups or anything.)

The virus in question is: Trojan horse Dropper.Delf.3.BE.

Do I need to do anything else? Do I need to be worried!

Thanks.

1) Download the following three items...

Trend Sysclean Package
http://www.trendmicro.com/download/dcs.asp

Latest Trend signature files.
http://www.trendmicro.com/download/pattern.asp

Adaware SE (free personal version v1.05)
http://www.lavasoftusa.com/

Create a directory.
On drive "C:\"
(e.g., "c:\New Folder")
or the desktop
(e.g., "C:\Documents and Settings\lipman\Desktop\New Folder")

Download SYSCLEAN.COM and place it in that directory.
Download the Trend Pattern File by obtaining the ZIP file.
For example; lpt307.zip

Extract the contents of the ZIP file and place the contents in the same directory as
SYSCLEAN.COM.

2) Update Adaware with the latest definitions.
3) If you are using WinME or WinXP, disable System Restore
http://vil.nai.com/vil/SystemHelpDocs/DisableSysRestore.htm
4) Reboot your PC into Safe Mode and shutdown as many applications as possible.
5) Using both the Trend Sysclean utility and Adaware, perform a Full Scan of your
platform and clean/delete any infectors/parasites found.
(a few cycles may be needed)
6) Restart your PC and perform a "final" Full Scan of your platform using both the
Trend Sysclean utility and Adaware
7) If you are using WinME or WinXP,Re-enable System Restore and re-apply any
System Restore preferences, (e.g. HD space to use suggested 400 ~ 600MB),
8) Reboot your PC.
9) If you are using WinME or WinXP, create a new Restore point
