If I hadn't read about the DNSChanger malware today I probably wouldn't have bothered but...

For the last month or two, my connection has been, pants. It started with my ISP server (BT) killing the connection across parts of the UK - I think other ISPs suffered issues as well - there was a general network outage - and it took about a week before I got my connection back. Since then my connection has been slow - kinda. When I reboot my router, it isn't unusual for it for my "Internet Connection Status" box to tell me I have a connection of say 1.2 Mbps (although I am not convinced I am getting that speed). After somewhere up to 5-10 minutes, the speed suddenly drops to half a megabyte or (at time of writing this) 160.0Kbps with the connection duration starting again from zero seconds. It isn't unusual for even basic websites like Google.com to get stuck trying to load etc. Basic websites with zero flash etc struggle to load.

Reading in the paper today, it said that one of the main symptons of the malware is speed of the internet connection being majorly affected. And since all the PCs on the home network (2 x desktops and a laptop that sometimes connects via wireless) is running slow and the malware can take over the router rather than specifically the PC then..........

Bullguard Virus came up clean... Malwarebytes has come up clean... I ran TDSSKiller and it came up with 14 threats (although I made sure all boxes were ticked including the additional options. One of the "suspicious" was \Device\harddisk0\DRO (TDSS file system). For all I know, this is perfectly normal and it is my ignorance that is worrying. (I shut down TDSSKiller without doing anything - I might be ignorant of some things, but I know not to actionanything).

Everything is probably ok, but if someone can help me run a few diagnostics to make sure my system is still clean then it would be appreciated. I did run the FBI's check tool on their website via the PCworld.com, but since it basically says a clean thumbs up proves nothing, I'd rather check with you guys.

- forgot to add the sytem is Win XP (if that is relevant)

You could try Eset.


ESET online scanner

Install it

Click on START, it should download the virus definitions
When scan completes, click on LIST of found threats

Export the list to desktop, copy the contents of the text file in your reply
You may not get a listing if nothing is found
