Suspect Javascript File

I’m running Avast Home Edition 4.1.418 on Windows XP Pro. I ran a complete scan of my local hard drive and Avast reported that Opr02itc.js, a file in the cache of my installed Opera browser was infected with a Trojan.

I tried to “move the file to chest” and “delete” but in both instances Avast said “This action cannot be performed on this computer”. I am logged on as an administrator and have never had this problem with Avast or any other program before.

I went into the cache folder to check the properties of the file, and after finding the file and right clicking on it the properties said the file was now modified. I don’t understand what a java script file is. Can I delete this file manually without doing any harm to the Opera browser?

After checking the properties of the javascript file I ran a second scan on the cache folder of my Opera browser and Avast did not report the file as infected.

Should I delete the file or just leave it alone?
Thanks for any insight into Java Script files!

Clear your Opera’s temporary internet files (cache).

Some sites use javascript for functions/navagation, etc. The cache is temporary, just clear it.

Thanks for the tip, will do!
