Has anyone had this problem?

I am sure my pc hides malware somewhere but I do not know what. I use windows 7. One day the pc stoped launching the windows explorer and it opened with a command prompt with the smallest size possible. Have gone to registry and fixed the explorer but i can't fix the command prompts size. Have deleted the settings from the registry to be remade. Have changed the properties manually. But nothing. Everytime a program opens a command prompt and it finishes it goes back to the small size erasing all the previous lines and keeping only one. I wouldn't have a problem with it except I try using Dev C++ and i can't see the results. Well if anyone has any ideas because the internet doesn't feel free. Also if this is in the wrong subforum then I am sorry and i will move it to the right one as soon as you mention it.

edit: specifically it defaults the dimentions to 15 width and 1 height.

have you tried a virus scan? 

[ufopro]

yes with avast and malwarebites. Nothing shown. maybe i should try a virus clean up method i saw on youtube the other day. had way more steps than that

[ufopro]

didn't detect anything either. I was hoping anyone knew about something other than a virus that causes this.

Use Autoruns to detect what is starting with your system. Use Spy Hunter to detect hardcore malware or even annoying registry hacks. And remove them manually since SpyHunter requires payment for making fixes (but displays all details so you can fix anything by yourself).
