I pulled this qyuote from another topic to avoid confusion between two unrelated topics in one.

Tony , I'm going to sit on this until you get help cos I have huge problems on my desktop...

BTW  Has anyone heard of a virus called BLOODHOUND, I may have contracted that yesterday.

There's several Bloodhound variants. Is this one asking you to buy something to remove it? What antivirus detected it?

I think 'bloodhound' is just the name given by Norton AV to anything detected solely by it's heuristic algorithm.

Which means it may not be a virus at all... in fact, if I had to choose between NAV popping a false alarm or finding an actual new virus with its clever algorithm, I would bet good money on the former.

So here's what to do:
1 - Download one of the free AV packages like Avast Antivirus
2 - Uninstall NAV. If you don't have the install disks to reinstall, turning it off may work too. Best to uninstall it though.
3 - Install free AV package, let it update its virus definitions and let it scan your machine

If it doesn't find anything, you don't have a virus.

It might also help to know - did you do anything risky lately? Visit a fishy website, open an attachment somebody sent you that didn't do what it thought it would...

This site contains some very useful information on what to do when bloodhound detects a virus:

Alot of other security companies list it as well, thats why I'm trying to find out more specific details so as to track down it's exact nature. There's threat levels on that name from low to high.

[silvero]

If it's referring to the bloodhound heuristic detection, it doesn't have a defined nature, it's suspected based on it's behavior.

I think nikster has offered very helpful advice however if the victim is unwilling to ditch a possibly paid-for program then an online scan is very easy and will give you the same result.

Good online scans can be performed at
http://www.kaspersky.com/
http://www.pandasoft.../ActiveScan.htm
and there's plenty more.

Also the victim can upload the Norton-suspected file for scanning by lots of AV engines for a more conclusive result:

I'm the clueprit.

What happened yesterday evening  was I somehow was invited to a website xxxleech.com after I clicked on a Rar file ( probably naughty) to find a password. Of course this directed me via IE to a paypal site. I got out as qqick as I could but suddenly up came WinAntVir inviting me to download / buy because I was infected with Bloodhound in huge capital letters.

My Mobo started to overheat so I switched off.

I've started a new topic explaining / begging for help

That explains a lot more about your problem.  So try the steps in my PM - re-install the rundll32.exe (often replaced or removed by a virus/trojan), run Virus/adware scans (Ad-aware, SpyBot S&D).

This virus has been around since 2004 apparently.

Had to look up Heuristic

Quick definitions (heuristic)

# noun:   a commonsense rule (or set of rules) intended to increase the probability of solving some problem
# adjective:   of or relating to or using a general formulation that serves to guide investigation

Is ending tasks via Task Manager likely to cause system problems, so long as those tasks are not system related ??

Heuristics in anti-virus refers to watching for virus-like activity. AVs with good heuristics are the ones that tend to get viruses that are 'in the wild' but not cataloged in their latest definitions download.

You can end tasks without breaking the system but unless you know whats what it won't be too effective. In the worst case just reboot if you mess up.

If you go to http://www.iobit.com and download the free Advanced Windows Care program it has a startup files monitor that will explain to you what most of the files auto-starting are and show you how to turn them off with a click if they aren't needed. It also has a decent antispyware and system tune-up program.
