Microsoft Free Antivirus Releasing Today

Microsoft has been working for a long time now in giving a good and reliable antivirus platform for all users. And when I say “for all users” I mean a free one. Seems that the dream is about to become true today: Microsoft Security Essentials will be release to the public as the free antivirus solution from Microsoft.

Microsoft Security Essentials will be replacing Windows Live OneCare as the security suite for viruses and malware. The suite can be installed in Windows XP, Vista and 7; and seems that already has a good review about the protection you can achieve, by giving you a shield for 97,8% of the existing malware in the web.

On the other side, some of the other reviews this antivirus platform has received so far say that the engine inside it is a little bit slow and intrusive with other applications.

And of course, leaders from other security solutions already are trying to tear this solution down, like McAfee: “will compete against other free solutions by offering limited security functionality”; or Symantec saying it is a “thin defense” and not giving you any type of antispam or identity safeguards.

Let people decide then.

Spam Increased 141%

Spam levels have increased in the last few months, since March more precisely, in a 141% said McAfee Threat Report from Second Quarter in 2009. The main reason resides in another increase: botnets (infected computers used for spamming and other attacks) up to 16%. Need an explicit number? That translates in 117 billion spam emails every day.

The number that is quite disturbing as well, is the botnets that are currently infected: 14 million computers. 150k every day, that represent 20% of all the computers that are acquired every day. And these botnets and zombies they are not only responsible for most of the spam, also they generated other attacks like denial-of-service to the White House, New York Stock Exchange and South Korean government web sites.

About South Korea, that’s the country that increased the most in the botnet activity, up to 45%; but yes, the US keeps in the top of that list with over 15% of the entire zombie population.

These spam numbers do not come alone, malware attacks have increased, specially the ones that infect the Windows auto-run that do not require any user intervention to “spread the evil”. That type of malware even outnumbered the Koobface or the Conflicker attacks.

This is a battle that will never end I think, I’m sure that those that depend on this kind of battles will not let it end.

What do you think?

Koobface Attacks and Twitter

Koobface malware found his way to infect thousands of Twitter users in the last days, increasing of course the number of Twitter updates giving messages like “My home video [url]“. The URL mentioned is listed randomly, all directing the traffic to a Koobface site.

Twitter’s reaction was fast and already suspended most of the users infected to avoid the virus from spreading. TrendMicro blogged about this and is already giving their users the solutions if they were infected.

This is apparently the second attack given by Koobface in Twitter, the first one used only three different TinyURLs with infected users; this malware mutation gave the infection a longer life than the previous one, that also appeared on Facebook, MySpace, Bebo, Hi5, Friendster and LiveJournal.

There’s no question about it, when you are that big, you will always have attackers and damage control will be needed.

Is YouTube Infected?

It was reported over on Techcrunch and Crunchgear that there wa a virus that was running rampant across the YouTube network with the certain embedded videos. It was reported that Internet Explorer (IE) and Firefox were targeted, later reports said it was just IE.

The virus was reportedly named Actns/Swif.T and contains a phishing scam that directs uses to a website with an embedded .SWF and then installs a program called “Antivirus 2009.” Users were warned of this potentially damaging malware by avoiding weird pop-ups, requests for personal information, or re-direction to unknown sites.

The story was later recanted as it appeared to be a YouTube specific situation. On the back end the virus protection service being used was returning false positives identifying code within certain embedded videos as malware. The entire incident is harmless, and there is no security breach on the YouTube network. Spokesperons from YouTube are handling the situation and ensure us that YouTube is currently safe and free of any malware problems.
