I don't know why, it seems that the "Search King" Google and Microsoft doesn't like Opera. I can understand why Microsoft sort of hates Opera, and you can find alot of news and rumours on the dark side between Microsoft and Opera. However it seems that there is no negative news that shows Microsoft hates Firefox. For Google, I still remember GMail does not support Opera when it first open the service to public. Now the problem no longer exists. But then, Google Reader and Opera is not living in harmony. In Opera, the elements in Google Reader are cramped up together. Firefox is working fine on it. It seems like Google and Mozilla has some sort of alliance thing between them. Maybe open-source thing will always be the most attractive/peaceful ones among others eh ?

I'm a big fan of Opera for years, but I don't hate Firefox. I still use Firefox once in a while. However, it's just a pain in the ass (alright, maybe it's not that serious) to open Firefox specially for Google Reader, while using Opera to surf other websites. I use Google Reader almost everyday to read news/feeds. For Opera fans out there, here's a fix to make Opera to work perfectly with Google Reader :

1. Download Reader.js (contributed by unknown coder)
2. Visit Google Reader main page
3. Go to Tools menu, select Quick Preferences -> Edit site preferences -> Scripting. Under the Use Javascript file, point that to the newly downloaded Reader.js
4. Refresh the page and get ready to read thousands of feeds that you subscribed ;)

Enjoy ;)

Virustotal is an online service for scanning virus/malicious/suspicious files using several antivirus engines. Oh ya, did I forget to mention it's free too ? I'm not sure if it can detect packers or not.

Another good free online file scanning service will be Online malware scan by Jordi Bosveld. Besides scanning, it supports simple packers detection. I used to use this but lately it seems the server load is always extremely busy, not sure if the server got bombard/flood or there are really so many people using it.

I suggest scanning both packed and unpacked suspicious file that you want to scan in order to get the best result.
