As a computer consultant I advise many of my business clients also on their home computers, and some have software on their home computers which send me an email if they get a virus. I wrote this today for one of my customer and expect that I can point folks here instead of rewriting it every time.

Although clamwin antivirus software has moved and nullified the trojan - you may wish to find out why, and how, the users of your home computer are doing things that got this trojan installed.

1. AOL, Yahoo or MSN instant messaging - using the program provided by the company (AOL / Yahoo / MSN etc) instead of a more secure alternative. It may be difficult to get your family to use a different chat program, even tho it would access the same networks ... simply because they are used to, and know how to, install / activate etc the insecure ones from the original company (AOL / Yahoo / MSN etc). Please find out who (in your family) if anyone - is the chat program user, what program they use so I can suggest a secure replacement or other mitigation.

2. Are they using Internet Explorer?

3. Are they visiting questionable sites (game sites, "weird stuff" sites etc) --- and agreeing to download and install EXE files?

4. Are they using peer to peer file finding software to get free music / vids / software? A vast majority of files on those systems include viruses (Kazaa, Limewire, Morpheus, tons of other network / system names that promise you FREE programs / music / video / shows etc.)

5. Are they using MS Outlook for email?

6. Are they trickable into clicking on attachments in email and executing files such as .scr, .pif, .exe, .vbs, etc etc etc
