Well, i was surfing on the web, i found a site, then i clicked home and it dowloaded a file named FlashPlayer12push.exe, i quickly deleted it, and like 10 secs later, my avast warned me that a malware or a program was going to disable it!, i clicked additional informations and nothing was there. i did a quick scan, no viruses, now i am doing a complete scan, and i got a print of the virus(where)

Maybe Avast caught it when the file operation (to recycle bin?) was moving/removing the file. If it’s indeed gone and Avast can’t show it in additional info, the file is probably indeed gone and you’re clean.
