Viruses detected, and emails sent advertising Viagra

**SparkySteve** · 19-12-2007, 10:41

In the office we've had a spate of the daily scans run by AVG finding and sorting viruses. Worrying in the sense that to my knowledge, no-one is downloading donkey porn.
However, one of the girls had a bounce notification saying that the email addres "fo@companyname.com" doesn't exist, however it was trying to send in from that same address.
Advertising Viagra, of course, and saying something along the lines of "For every $1 spent you'll get a $2 return!". Now, the girl in question doesn't like donkey porn (I asked) so i can only assume that the PC has been "trojaned" in some way to get her email account sending dodgy emails.

Has anyone seen this before, or can you reccommend a quick scan-like tool to get this sorted?

Cheers,
SparkySteve

I would use AVAST as it runs all the time in the background, So if anyone does open a dodgy email or downloads anything that has a trojan/virus/worm it alerts you straight away. I have it on my pc and laptop and it has found a few.

EDIT: but i do look at a few porn sites

:D

Sounds like one of your boxes has been compromised.

You'll need to find out which machine it is and fix it.

Any dramas send me a PM.

We're in the process of upgrading to AVG PRO so i'd rather not bog the machine with another anti-virus to be honest, that particular rig runs 500meg RAM!

B20, cheers for the link mate, if i can't sort it in a couple of hours i'll have a word!

Email address spoofing is a fairly standard thing that many viruses do. There is a better than average chance that a virus, on someone elses computer(outside your system) has been infected. The virus will then use the resident address book entries in the "from" headers on the shit it sends out.
