Safer Surfing in 'Virtual' Environment

With normal surfing information is loaded from your hard drive and then through your browser where information is then written back to your computer, if it’s a malicious site then you will also have malware written to your drive.

What if you could use a ‘virtual area’ in which you can run your browser, email reader, instant messengers and programs in complete safety. The information is loaded from your hard drive into the 'virtual' environment, from there the read/write operations are carried out within the 'virtual' environment and never back to your computer.

MSN Messenger Spreads Viral Attack Through Users

Please read the complete article before following the steps given.

Once again more MSN Messenger Viruses are spreading around the Internet. This time the virus sends the following message to all your contacts:

cute.pif - W32.Kelvir.A

omg this is funny!
[Followed by a link to download the cute.pif from jose.rivera4.home.att.net]
The user then downloads the file which sends the link to all of their contacts and then downloads a W32.Spybot worm onto the infected machine.

If your are lucky the program will just run on your machine, send to your contacts and end without downloading the Worm.

The first thing you should do therefore is delete the downloaded cute.pif making sure you do not run it again! Then check to see if a Worm has been downloaded as well.

1) Press Ctrl+Alt+Delete and look for hotkeysvc. If it’s there select it and press “End Task”.

2) Use the Windows Find feature to look for a file called “hotkeysvc.exe”. Which if their should be in the %System% directory. If you find the file delete it.

W32.Annoying.Worm

The delightful author of this worm, who comes “in piece” (pity it’s not “in pieces”), has even included a readme.txt file with uninstall instructions:

How to remove the Annoying.Worm:
1) Click Start, select Run. The Run dialog box pops up.

2) Type: msconfig The System Configuration Utility pops up.

3) Click the Startup tab at the top. In the list, find MsgSprd, Messenger, or pic1324, uncheck, press Apply, then press Ok.

4) Restart your computer Or press Ctrl - Alt - Del, select MsgSprd from the list, then press End Task.

You may freely delete the files or the ‘C:\Messenger1324′ directory.

You may need to uninstall/reinstall Messenger after removing this one from your system.

As you may have passed the MSN Messenger virus on to some of your contacts it is suggested you warn your friends about the MSN Messenger Virus.

Many of these viruses will continue to resend themselves to your contacts and then their contacts, so the vicious circle continues. If you are infected you are in a position to do something about it.

In future if someone tries to send you a file on MSN Messenger and it ends with ‘.exe’ do NOT download it unless you are really sure you know what it is. Ask the person that is sending you it what it is!

Ensure that your pc is fully up-to-date with the latest patches, also ensure that your anti-virus protection is regularly updated.

If you use a file shredder it is better than using the recycle bin to empty files.

I also recommend using CCleaner (formerly CrapCleaner) to rid your system of unwanted garbage that collects on a daily basis.

Virus Alert

Some 30% of computers with a security solution installed scanned last week were infected with some kind of malware. In the case of computers without any kind of protection, the figure goes up to 44%. Source:http://www.infectedornot.com

Malware creators are trying to put a large number of threats in circulation and install them silently to prevent security companies from detecting them and generating the necessary vaccines.

Therefore, traditional security solutions must be complemented with other types of online solutions like BitDefender, which uses the ICSA Labs certified scanning engines, so you can feel secure about their virus protection.

As for the malicious code that has appeared in the past week, highlighted are the Bindo.A and Nuwar.HU worms.

Bindo.A aka autoply.exe is a worm designed to spread and infect as many computers as possible by copying itself under names like autoply.exe or MSshare.exe to the shared folders of any P2P programs that the targeted user might have installed.

It also creates a file called AUTORUN.INF in all drives it copies itself to, in order to be run every time that the drive is accessed It is very easy to detect the presence of this worm on the system, as it increases the number of shared files in the P2P shared folders on the computer.

Bindo.A also changes certain shortcuts in the desktop so that they have two execution paths: the original one and one that runs when the original program is launched.

BitDefender is a FREE online virus scanner, which takes a while to run and it is advisable to run this when you have no other programs using resources. When opened, you will have to click the ‘I Agree’ user license after which you will be taken to the Options page.

Click image for larger view.

The default setting is to scan all of your computer, which is the safest option. Under the ‘Settings’ the default option is for BitDefender to try and clean the infected files. There is a warning that if disinfection fails, the files will be deleted. You can change this option where it says ‘click here’ and a pop-up window opens (ensure you do not have pop-up blockers turned on).

Click image for larger view

Under the heading ‘Action options’ select ‘Prompt user for action’ and under ‘Second action’ again select ‘Prompt user for action’ then click OK, then click where it says ‘Click here to scan’. BitDefender will then load the anti-virus engine and virus signatures.

If it fails to update, select ‘Yes’ to continue and scanning will start.

Click image for larger view

When scanning, if an infection is found you will be prompted for an action and you will see the location of the infected file. You can select ignore, disinfect or delete. If disinfection fails however, the file will be deleted so use this with caution and ensure that it is not an important file.

Nuwar.HU is a new variant of the infamous “Storm Worm” which takes advantage of Halloween to spread. It ends processes of certain security tools that might be installed on the computer.

Nuwar.HU drops a rootkit called noskrnl.sys on the system and sets it as a service so that it is run automatically when the computer is started. Nuwar.HU spreads in email messages with subjects like “Have a Happy Halloween everyone” or “Party on this Halloween” among many others.

These messages include links to certain web pages that show a ‘dancing skeleton’ animation. If the user downloads and runs the animation offered on the website, the worms infects the computer and turns it into a zombie system at the service of a malicious user.

Rootkit detection

Methods to detect rootkits fall into two categories: Signature-based and heuristic/behavior-based detection.

There is an article about rootkits here and advice on searching your hard drive for the presence of rootkits and tools to remove them which you can get more information by clicking here.

Secunia Personal Software Inspector (Beta)

Make your PC safer with this utility from Secunia, a company that tracks known vulnerabilities in software and operating systems.

This is one of the most useful and important free tools that you can have running on Windows XP SP2, Windows 2000 and Windows 2003.

This tool examines all of the program files on your PC for information on specific software builds installed and can identify missing Windows patches and outdated, insecure applications on your PC.

After examination, the data collected is sent to Secunia’s secure servers (https://psi.secunia.com/) and matched matched against their Signature Files which then determines the precise applications installed on your system.

Secunia state that they have more than 4,700 different programs in their File Signatures engine.

Once the scan is complete, which only takes a few minutes, Secunia PSI will categorize each program as “Up-To-Date”, “Insecure” or “End-of-Life”.

Click images for larger view

The results table presents the name and version number of your installed application. Clicking on the file name or the green information button will take you to a summary page with further information. If there is a blue button this will link directly to the file that will update or patch your software, if available.

On the summary page you will also receive a link to Secunia’s advisory about why your version is not safe, and explanations of the multiple versions of a program that you may see listed, as well as available updates and download locations.

Although Secunia PSI is not perfect, and it is still in Beta version, it is fairly useful at keeping your computer programs up-to-date, which also aids in your system security.

Secunia’s privacy statement states that they store information about your software for up to 12 months, but it does not collect any personal data beyond version numbers.

Download Secunia PSI here.

Note: The free Secunia PSI is available for Private/Home Users ONLY

As with any program installation, Backup or create a Restore Point before making any changes.
