How To Do A Free Online Virus Scan


Use Free Tools Provided by Anti-virus Companies

Do you think your computer might have been compromised? No anti-virus, no problem. You can do an online virus, spyware, and malware scan using some free tools on the web.

Housecall – Mac, PC and Linux

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 Online Scanner – PC and Linux

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.

Greeting Card Virus


A computer virus has been circulating as a “Greeting Card” email message. The message title contains the words “Greeting Card”, “E-Greeting”, “Christmas Card”, “Online Greeting”, “Greeting for you” or some variance thereof. When the link is followed to view the greeting card, the computer then becomes infected with a virus or trojan (see below for more about what this is) by running ecard.exe.

Please don’t click on any links one of these emails.  Especially if you do not know the person that supposedly sent you the greeting card.  Once again, if you receive an email that meets the above criteria, please delete it.

greeting_card_email

As a matter of principle, I don’t believe in sending E-Cards as they (the companies that provide the e-greeting service) can be used to collect and sell “valid” email addresses to other companies.  Please take a look at my 9 Tips to Less Spam post for more info on how to avoid getting spam like this.

Cleanup Info

Symantec has some info on how to cleanup the trojan.  Basically disable system restore, update your virus definitions, do a full virus scan, and cleanup the registry.

Trojan Info

A trojan is a malicious program that collects information about your Internet activity and send that info to other websites where the information is collected.  Some are very sneaky and collect keystrokes, password and bank login information.  Bottom line is, don’t get a trojan.

Microsoft Plans to Give Away Anti-Virus Software


Free Core Protection Software to be Offered by Microsoft

Microsoft has recently announced their plans to release free software to protect against viruses, spyware, and malware.

anti_virus_scan

The word from Microsoft’s press site:

Code-named “Morro,” this streamlined solution will be available in the second half of 2009 and will provide comprehensive protection from malware including viruses, spyware, rootkits and trojans. This new solution, to be offered at no charge to consumers, will be architected for a smaller footprint that will use fewer computing resources, making it ideal for low-bandwidth scenarios or less powerful PCs.

Microsoft has also stated that they will stop charging for their Microsoft Live OneCare Solution in favor of the free “Morro” solution. Beginning June 30, 2009 you will no longer be required to update your subscription to OneCare. You can read more about OneCare on the OneCare blog.

The “Morro” solution will be a downloadable package and will not be bundled with a new PC or OS purchase.

Will this mean doom for other anti-virus software vendors?

Probably not – Most vendors have both a business version of their anti-virus software and a home user version. Companies like Symantec and McAfee can continue to offer their products to enterprise clients. In fact, Microsoft will continue to charge for their business version of anti-virus software.

These vendors typically bundle additional “non” anti-virus services with their products that consumers feel is a value add. “Morro” will provide only core protection and won’t include some of these additional features.

Really Free?

Free anti-virus software is nothing new. The current home user can download free anti-virus programs from AVG, Avast, Avira, Trend Micro and others. Most free anti-virus programs will try to up-sell you additional products or have some functions disabled. “Morro” is free, and from all reports Microsoft won’t try to up-sell you products that can provide additional protection.

I like the fact that Microsoft is offering the software for free. It allows users who wouldn’t ordinarily be protected from malware and viruses to have at least a small level of protection. I think the average user will feel more comfortable opting-in to a service that is provided by Microsoft rather than some other third party.

Consumers will ultimately decide whether or not “Morro” will be of value. Will it detect malware or spyware as efficiently as other products on the market? Or will users simply continue to use their McAfee, Symantec, etc… subscriptions?

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.
