Conficker Alert

Kanina, sa BK, sobrang worried ako na may virus na ang laptop ko. Pa'nu ba naman, kakabasa ko lang a Yahoo News ang tungkol sa isang "high threat" computer virus na kumakalat ngayon:

Tomorrow -- April 1 -- is D-Day for Conficker, as whatever nasty payload it's packing is currently set to activate. What happens come midnight is a mystery: Will it turn the millions of infected computers into spam-sending zombie robots? Or will it start capturing everything you type -- passwords, credit card numbers, etc. -- and send that information back to its masters?
No one knows, but we'll probably find out soon.


Or not. As Slate notes, Conficker is scheduled to go "live" on April 1, but whoever's controlling it could choose not to wreak havoc but instead do absolutely nothing, waiting for a time when there's less heat. They can do this because the way Conficker is designed is extremely clever: Rather than containing a list of specific, static instructions, Conficker reaches out to the web to receive updated marching orders via a huge list of websites it creates. Conficker.C -- the latest bad boy -- will start checking 50,000 different semi-randomly-generated sites a day looking for instructions, so there's no way to shut down all of them. If just one of those sites goes live with legitimate instructions, Conficker keeps on trucking.

Conficker's a nasty little worm that takes serious efforts to bypass your security defenses, but you aren't without some tools in your arsenal to protect yourself.

Your first step should be the tools you already have: Windows Update, to make sure your computer is fully patched, and your current antivirus software, to make sure anything that slips through the cracks is caught.

But if Conficker's already on your machine, it may bypass certain subsystems and updating Windows and your antivirus at this point may not work. If you are worried about anything being amiss -- try booting into Safe Mode, which Conficker prevents, to check -- you should run a specialized tool to get rid of Conficker.

Microsoft offers a web-based scanner (note that some users have reported it crashed their machines; I had no trouble with it), so you might try one of these downloadable options instead: Symantec's Conficker (aka Downadup) tool, Trend Micro's Cleanup Engine, or Malwarebytes. Conficker may prevent your machine from accessing any of these websites, so you may have to download these tools from a known non-infected computer if you need them. Follow the instructions given on each site to run them successfully. (Also note: None of these tools should harm your computer if you don't have Conficker.)

As a final safety note, all users -- whether they're worried about an infection or know for sure they're clean -- are also wise to make a full data backup today.

What won't work? Turning your PC off tonight and back on on April 2 will not protect you from the worm (sorry to the dozens of people who wrote me asking if this would do the trick). Temporarily disconnecting your computer from the web won't help if the malware is already on your machine -- it will simply activate once you connect again. Changing the date on your PC will likely have no helpful effect, either. And yes, Macs are immune this time out. Follow the above instructions to detect and remove the worm.


Napansin kong ayaw mag-update ng Windows. Ayaw ding mag-update ng mga anti-virus software ko. Sabi sa mga nabasa ko, sintomas ng naturang virus ang mga gayon.

Kaya pag-uwi ko ng bahay napa-download tuloy ako bigla ng Windows Live OneCare.

Matapos ko naman ma-scan ang system using it, buti naman at wala namang virus. Nag-update din ang OS ko pagdating dito sa bahay, so I guess 'yung internet sa BK ang may problema. Grabe. Lecheng False alarm yan. Di pa man din ako marunong mag-reformat nito.


===========================


Haaaaayy... Ayokong-ayoko talaga na nakaksira ng mga gamit ko. Lalo na at bigay lang sa akin. Nakakahiya kasi sa nagbigay sa 'yo kung masisira mo 'yun. Kaya madalas, tumatagal ng taon ang gamit ko parang 'yung celphone ko na mag-tatatlong taon na, na ngayong taon ko lang pinagawa ever.

So kapag may ibinigay sa akin, pinagsisikapan ko talagang alagaan. Parang "trust" lang. Gets? :)

===========================

EDIT: May nakita akong Conficker Detection Tool. Astig 'to. :P

(Mukhang mapapahamon ka jan DN ah. Haha.

Okay so i-English speak na rin ako.)



The other day, my laptop went semi-dead. I was unable to run any windows executables, and the programs that run on start-up where missing. Good thing a friend of mine found where the problem is.


(O haa!)
