This problem started the other day (around 4-5 days ago). I ran an internet cafe and my computer is connected to the net and to a LAN the whole time the shop is open so I don't where I got this. First the computer was so slow, that opening a simple wordpad document is a pain, so I clicked on the task manager to check which of the program that is open at that time was using all resources and I saw Dnsclnt.exe. I use this trick (if you can call it that) of closing whatever program that is slowing down the computer, off whenever my computer slows down. And this is the first time I encountered Dnsclnt.exe. It took a while to stop it (it just won't stop running in one click you have to stop it a couple of times before it would stop) and we noticed a considerable change in the speed of the computer. At that time I just ignored the problem, and attributed it to my surfing mulitple sites, while doing a dozen other stuffs on my pc for the slow down. It was a while before we (my assistant and I) realized that it's the Dnsclnt.exe that is causing the problem. I've been scanning my computer for viruses and spyware for the last two days already but still the problem won't go away. I used AVG Free edition (Dnsclnt was not detected at all), Nod32 (Dnsclnt.exe was reported and cleaned, but the problem came back as soon as i rebooted), Ashampoo (also trial version) same as Nod32, dnsclnt.exe was reported but problem came back as soon as I rebooted.

I also tried stopping it from running by disabling in msconfig (I saw a friend do that with krag.exe and I thought it might work with this one) but it would still load itself upon start up.

I hope somebody in here could help me. Thanks in advance.

this is my hijackthis report of my pc now. (I took this after scanning and cleaning my computer using ashampoo)
