Hi! I didn't see a "Virus" forum, so "Security" seemed the place....


A co-worker has handed over an infected Dell Dimension 3000 (Celery Processor).


Before I start doing anything I would like to know a few things:

1) If I attach the infected PC to my network via a switchbox is it possible for the virus(s) to be transferred.

2) If I copy files from my system to the infected PC via a thumb-drive, is it possible for the virus(s) to transfer to another PC when I use that thumb-drive again on a healthy PC?

3) If it were you, would you simply access the internet on the infected PC directly via the modem, and never allow digital contact with your system(s)?

I am asking these questions as I need to get programs like Ad-Aware, SpyBot, Hijack This on it.

This system belongs to our Sales Representatives' teenage daughter. There is a high probability that "Kazaa" is involved.


Any assistance or sharing of experiences with this issue is greatly appreciated. Thanks for your time.

Possible, but highly unlikely. Unless its some really advanced virus that will spread itself through the network by file sharing or something; most likely won't happen.

2) If I copy files from my system to the infected PC via a thumb-drive, is it possible for the virus(s) to transfer to another PC when I use that thumb-drive again on a healthy PC?

This won't happen either 99% of the time unless you transfer files from the infected PC onto another healthy one. But.. there are advanced viruses out there that will copy itself onto whatever you connect to that PC and then keep on spreading.

3) If it were you, would you simply access the internet on the infected PC directly via the modem, and never allow digital contact with your system(s)?


Well, If it was me I would allow it to connect to my network because I have programs monitoring all ports on the network and its guarded against netBIOS, DoS, and a bunch of other crap.

I am asking these questions as I need to get programs like Ad-Aware, SpyBot, Hijack This on it.

If you want to get those files onto the infected PC then download them from a clean computer and burn them onto a disc then transfer to the infected PC through that. Also, it would be a good idea to install programs like AVG or Avast! (! is part of the name) anti-virus programs on the computer too. If its a real nasty virus and has infected the registry alot then use Abexo registry cleaner to try to clean it out.

The best way to get rid of a virus is by reformating, do that if you have tried every anti-virus/spyware program and it still doesn't come out. If reformating doesn't work then change your motherboard BIOS chip, some viruses hide in your motherboard's BIOS memory and then it loads itself into the fresh reformated HD so it will always be there again.

Tell her to use FrostWire.

lol ya, I was gonna recommend a CD. That's the first thing I woulda thought of....no transferring around anything...just pop the CD in, Plus you can use it again next time something likethis happens to a friend/make a copy for them.

Good advice JAckO
I've been through the BIOS resident issue before.
It required removing all memory resident hardware, an overnight clearing of the BIOS including removing all power sources to the MB!
As you may have suspected, the write to BIOS was enabled allowing the above problem to happen!
They can be difficult to detect, but the BIOS write enable threw up the flag when every menas of cleaning the system failed, including removing the RAM overnight and then the HDD and scanning and file shredding via a USB hook up on another PC.
