NanoScan: 1 minute online virus scan

NanoScanYou know how most anti-virus/anti-spyware software can take up to an hour to run, bogging down your computer in the process? Turns out there's a faster (if slightly less thorough) way to give your computer a quick checkup.

Panda NanoScan is a browser-based program that scans for viruses, trojans and spyware. Since the database sits on Panda's servers, there are definitions for you to download. You just need to install a 400kb plugin the first time you run NanoScan with Internet Explorer or Firefox.

NanoScan doesn't search every single file on your computer for malware. Instead it takes a look at all your active processes and a set of crucial files and folders. The result is a blazing fast inspection, which takes just about a minute to run. If you want a more complete scan, you can run Panda TotalScan, which is larger, takes longer, but performs a more thorough search.

The service also collects anonymous user data and displays the results online.

Now the downsides. There's no support for Vista yet, although it's in the works. Also, NanoScan and TotalScan find problems, they doesn't fix them. Obviously these browser-based solutions also don't offer real time protection if you download an infected file. So they're not replacements for a PC-based anti-malware program like AVG Free.

Edit: TotalScan does have a disinfect feature. You have to register (free) in order to activate it.

Google warns that 10 percent of all websites contain malware

Windows DefenderGoogle released a study last week (pdf alert) suggesting that 1 in 10 web pages could contain viruses that can be forcefully downloaded to your computer. The report says that an average of 8,000 new web sites with malware were developed each week during the month of April.

The take home point here is that we're not just talking about shady websites that you wouldn't trust with your credit card information. More and more often, legitimate websites are being infected with malicious code by hackers. Simply visiting these sites could be enough to allow an attacker to find and exploit vulnerabilities in your system.

Interestingly, the report serves to scare the pants off of its readers by saying "average gumputer users have no means to protect themselves from this threat. Their browser can be compromised just by visiting a web page and become the vehicle for installing multitudes of malware" while they are unaware.

Of course, the simplest thing you can do to protect yourself is turn off JavaScript in your browser, but that could also mean missing out on many rich media features on the web. So the next best thing is to get yourself some good anti-virus/anti-spyware software and run a complete scan every day. You might want to check out AVG Anti-Virus Free and Windows Defender for starters.

The World's Hardest Game 2.0 - Time Waster

So, just how good at time waster games are you? Think you've got the stuff? Well, The World's Hardest Game 2.0 doesn't think you do. Yes, amazingly, it's possible to have a sequel to a game called "The World's Hardest Game". It doesn't seem logically possible, since if the first one was actually the world's hardest, how could another one come along and share the moniker? It made me doubt the name in the first place. That is, until I tried the game. The mechanics of the game are very simple. You are a small red square, ...
