I am utilizing dell inspiron 530 desktop and I am utilizing from last two years. Mostly I apply my desktop for utilizing net and seeing picture. I was set up AVG antivirus which died earlier last one month. After antivirus died I apply my desktop minus any antivirus. Earlier few days I set up AVG antivirus again in my machine. After set up antivirus I scanned my total system and it detects 36 infected files. I earsed those files but after that when I restart the desktop at that time my machine is not opening.
