xpdx.sys has not been able to open this file - does not exist?

On do some searching I found this 'Infected/Virus/Smitfraud?'

Is this a threat? How do I deal with it?

Can Clamwin fix this threat?

Smitfraud is a trojan spyware family. It has been around a few years, so most good antispyware programs should be able to remove it. Problem is--it may have hidden/rootkit functionality.

To try self-removal, get a good antispyware program--such as SuperAntispyware or Windows Defender. Install the antispyare program and then put your computer into Safe Mode and run the program. Safe Mode makes it harder for malware to hide from security software.
To get into Safe Mode, reboot your computer and press F-8 repeatedly every second or so when the screen comes on. Don't be scared when you see some "junk" come up. When Safe Mode comes up, you will know--the screen will have Safe Mode in all four corners. Then just run the antispyware program from the Desktop or via Start/All Programs. You might also run your antivirus software right after this.

If this doesn't work, or you would rather have expert help, the Castle Cops website is probably the best place to to. It is at https://www.castlecops.com/f67-Hijackthis_Spyware_Viruses_Worms_Trojans_Oh_My.html. Ask for help. They rely pretty heavily upon the free Hijack This software. One of their experts will tell you what to do. This is a very good site dealing with computer security. It is so good that the malware writers hit it with a Denial of Service a few months ago, but they are back with a stronger site.

Thanks for the feed back.
In the mean time I downloaded and used Prevx 2.0.
This has prettymuch solved all the problems and the computer is behaving normally again.
Trouble is it is a trila which will work for 30 days.
Then you have to buy it.
Perhaps I should move to Ubuntu Linux and be done with all the hassles.

I'm glad you were able to remove it. It sounds like Prevyx would be worth the price you pay for it. ClamWin doesn't do any disinfecting. You have to configure it to quarantine any malware it finds and then remove it yourself. If you like the behavior blocking software, Cyberhawk is free. It beat Prevyx in last year's AV Comparatives test.

Regards,

I have now downloaded Cyberhawk as well.
Both are running at the moment.
Cyberhawk did not find any problems at the moment.
Is it neceassry for me to have both programs up and running?
I am reaaly a bit worried about the ease with which someone can snoop around your files without any permission.
Where do the attacks come from? Can they be traced?
