How to get rid of a file?

I have a hp mini not too long and I have a problem with it. I recently found a folder on my main hard drive. I looked at him and is a proxy code for spyware. You extesion file (dll) and crashes. I ran into this problem on my computer and I also Deskop was able to delete from there with the creative element implementation tools. I have a virus on my hp mini, is the rogue antivirus "total security in 2009. Quickly I realized it was a fake and I am trying to get another program of existence, but not let me. Total Security 2009 will not let me open programs or get into safe mode. Locked files can not be deleted manually, you have to use the program to remove them, but I can not open it. I can not do a system recovery because my laptop has no cd drive. What I can do? I've been researching a lot on it, but have not found a solution.

Since that will not open any program, I suggest going to http://bleepingcomputer.com and run a HJT. These guys are good and tell you how to eliminate you. Sometimes a reformat and reinstall is the best and quick solution
