Severe Virus - Problem

[Tristan]

Hi, don't know what I did to get it yesterday but I'm constantly getting popups alerting me to a 'TrojanDownloader'
I have Windows Defender but I was prompted to download other Antivirus programs.
I'm getting a flashing yellow triangle with a ! inside on my 'Notification Area' (bottom right).
I missed what it said but I'll say next time it pops up.

Please help.
I try using 'Quarantine' on the virus with Wondows Defender, Remove and it just won't go.

Download Ad Aware SE Personal (free). It's a well known program and you can scan your computer for viruses. It never has any problems removing them. If windows defender can find it, ad-aware will find it and remove it.

Sounds like a Rootkit to me.
You'll need to check your registry and delete anything that looks suspicious (regedit)
Open Task Manager, and end any processes looking dodgy (CTRL - ALT - DELETE)
And have a Full Computer Scan

if it doesn't go away just store the files you want on a USB stick or sumit

and format your master drive

Do not do this unless you know exactly what you are doing, seriously.

While that's correct, it's absoultely necessary.

Look in LOCAL_USERS and then SOFTWARE
and be wary of things you are 100% sure is dodgy, like 'Windows Protect AV', or products that don't exist, they're sometimes the Rootkit, masking itself.

That is not needed... It's simply a trojan downloader. He's downloaded a virus and it's running the background somewhere, giving him popups and downloading trojans.

If it's a rootkit and you want to save yourself a headache, use rootkitrevealer.

Make sure you backup your reg btw.

download kaspersky anti virus 2009 its the best ever

You can't simply say 'its the best ever' to a program, as it's probably nowhere near the best.

Try installing Spyware Doctor.
