Calc.exe causing serious threat ?????

[dreams]

Hi all..

I have a bizarre situation happening in my PC. Here it goes..

Few months back, My computer's behaviour was haywire.. All of a sudden calculator program pop-up randomly..say about 50-100 calc.exe pop-up.. I have to manually close them.. At tht point I was not having a AV.. Had only Kaspersky.. So turned off my modem and it stopped.. Thought some hacker hacked my PC.. Worried alot, I un-installed kaspersky and installed COMODO.

Was happy for few months.. 2-3 weeks back calculator pops-up again.. thought it was not a hacker and some trojan or spyware and installed nod32.. Was happy for few weeks.

2 days back the same thing occurred.. Out of curiosity chkd my taskmanager and there were a total of 150 processes running(Normal processes for my computer is less than 30).. calc.exe playing a major part in it.

Lightning struck my mind.. I have a compaq keyboard which has a button to launch calculator and other stuffs.. Long back I cleaned it myself by opening it.. Thought there might be some loose contact or short circuit and immediately pulled out the keyboard cable from CPU.. Again to my fate it stopped. (Confusing again)

Guys let me know if the above behaviour is due to hacking or spyware/trojan or keyboard fault.

Did a in-depth full system scan by nod32 and deleted 2 joke program that I had for a very long time.

What is causing this to happen???

Help needed at once.

Sorry for the long story..thought this problem must interest you.

Well it could be due to a fault in keyboard circuit, which causes unintentional button 'pushes'. I dont think there is any virus etc out there that does this. Try using a different keyboard for some time and see if it happens again.

I dont know about any hardware probs as in keyboard causing this... Its extremely rare. However its better to do these things in addition to checking/try replacing your keyboard.

1) download "hijack this" from here.
*www.download.com/Trend-Micro-HijackThis/3000-8022_4-10227353.html

then open it, click on "scan and save a log file" (or something similar) and after it runs the test, there will be a log file in .txt format. Save the file.

Then, either paste it here, or go to *hijackthis.de/ and upload/paste the contents of the file and scan for potential threats. They will be marked by a "x". Go to SAFE MODE and run the tool again and check these entries if any and Click fix now.

In case its a trojan, then you will need a trojan remover software or an extremely effective antivirus. My knowledge on antivirus is outdated. I dont use any. But i guess bitdefender, kaspersky are good.

in case you have more queries, post it here.

good luck,
