avast! detects a virus in my computer. It gives me several options to try, but none of them works. I also get a message stating Access denied. How can I solve this?

1. If you are using Windows Millenium Edition (ME), Windows XP or Windows Vista, disable System Restore feature first (watch the instructional video). If you're using a different operting system version than Windows XP or ME, skip that step. Then, you will need to restart your computer. For more info on this step, refer to Windows help, please.


2. Scan the file again. When avast! shows the Virus was found! window, click on Delete button.


3. Another small window will pop up. Here, check the option If necessary, delete file(s) at next system start, as shown on the following picture.
   
   
   
4. Restart your computer. After restart, the infected file should be gone.
