Downloaded Matrix reloaded today from Kazza, a file that was over 700meg. Tried to view it on MediaPlayer but it kept coming up saying an error had occured. Next thing i knew my puter was going slow and pages took ages to load and started to freeze up. I then decided to delete the file but as has been said before, it told me the file was in use by someone or some other program. Then i noticed the file was now only 4kb in size. SUREDELETE soon got rid of it, but my puter is not as fast as it was and there is no sign of any viri. Any ideas ? Tnx
