Housecall from Trend Micro will do an online scan of your computer. Tell you what it found and makes recommendations for keeping your info private, like removing cookies and temporary Internet files. Housecall is also capable of spyware and malware detection and removal.

Kapersky’s scanner also scans for malware and spyware. Seems to be a bit slow as it needs to download about 52MB virus definition files before it actually starts the scan.

BitDefender Online Scanner – PC only and must use Internet Explorer

Bitdefender also detects spyware and malware on your computer.

All of the above do not prevent viruses, spyware, or malware from infecting your computer. They are tools used to detect and clean an infected machine.

Recommend running a full scan from different anti-virus companies just to be safe. Instead of buying a product, this online solution fits well.

AVG Anti-virus Kills Critical Windows XP User32.dll File


AVG anti-virus recently released an update to their virus definitions file which incorrectly detected a critical Windows file as being a Trojan horse program.

Both AVG 7.5 and 8.0 (free versions and pay versions) incorrectly identified “user32.dll” as being a malicious Trojan program called PSW.Banker4.APSA (according to their forum post).

AVG Forum Post

Depending on the configuration settings chosen for AVG, the detection could result in the removal of user32.dll and the inability to reboot the PC.  User32.dll is a critical file which allows for API calls to the Windows Graphical User Interface.  If the file is missing during  boot, the computer will Blue Screen.

We get the following from Computer World’s report:avg

AVG released a follow-up signature update to correct the problem, but that solution only worked if the user had not turned off his PC, or rebooted it, after installing the buggy update and then deleting user32.dll.

AVG’s support website has some details on how to recover user32.dll in their support section.

Obama Virus


Hackers and phishers are taking advantage of your need for election news by using President-elect Barack Obama’s name to get you to click on links and run programs that will infect your machine with malware.

The latest deception involves sending email with a link to President-elect Obama’s victory speech.  The link will take you to a website that requires you to  install the Adobe Flash plug-in.  Not true.  The plug-in is really a Trojan horse that installs malware on the machine. obama_biden_logo

Here is an excerpt of the the email that has been going around:

From: “President election results”
Subject: A new president, a new congress …
Barack Obama Elected 44th President of United States

Barack Obama, unknown to most Americans just four years ago, will become the 44th president and the first African-American president of the United States.
Watch His amazing speech by clicking here

What does it do?

The Trojan’s main purpose is to steal passwords.  It runs in the background and looks for passwords, and can act as a keystroke logger.

Removal

You can remove the Trojan if you have your anti-virus software up to date.  In fact, if you do, your anti-virus will most likely stop you from getting infected, as it will identify the program as being a Trojan and prevent installation.  Don’t take any chances though.  Simply delete emails from sources you don’t know that ask you to click on links.

A computer virus has been circulating as an email attachment. The “From” address indicates that the email came from a UPS representative. The virus is a zip file attachment with the names of “ups_invoice.zip” or “ups_tracking.zip”, or some variance thereof.

This e-mail attachment contains a virus. We recommend that you do not open the attachment, but delete the email immediately.

UPS may send official notification messages on occasion, but they rarely include attachments. If you receive a notification message that includes an attachment and are in doubt about its authenticity, please contact customerservice@ups.com.

Please note that UPS takes its customer relationships very seriously, but cannot take responsibility for the

unauthorized actions of third parties.

Once again, if you receive an email that meets the above criteria, please delete it. Do not attempt to open the attachment.

Even if you have just sent a package, and think the email could be relative to you, please go to the web site http://ups.com and check the status of your packages online.
