Having anti-malware scanners is very important. However, it may not be worth it if the scanner itself make your computer ridiculously slow…The following virus scanners were tested to see which gave the lowest impact on system performance:

Avast! Free 5.0, AVG Anti-Virus 9.0, AVIRA AntiVir Premium 9.0, BitDefender Antivirus 2010, eScan Antivirus 10, ESET NOD32 Antivirus 4.0, F-Secure Anti-Virus 2010, G Data Antivirus 2010, Kaspersky Anti-Virus 2010, Kingsoft Antivirus 9 Plus, McAfee VirusScan Plus 2010, Microsoft Security Essentials 1.0, Normal Antivirus & Anti-Spyware 7.30, Sophos Anti-Virus 9.0.1, Symantec Norton AntiVirus 2010, and TrustPort Antivirus 2010.

The top five virus scanners that least impacted systems were: AVIRA, Kingsoft, F-Secure, Sophos, and Kaspersky. For a list of all the results, as well as a bunch of information on the testing, check out this PDF.

Microsoft Live Messenger Urgent Update

Looks like Microsoft Live Messenger has a severe security issue that must be addressed via update ASAP. The vulnerability itself is in Microsoft’s Active Template Library (ATL), which is being used by Live Messenger, as well as other programs.

Microsoft’s Live Messenger appears to be among the programs affected by the critical ATL security holes. Holes Microsoft recently closed with emergency patches for the Visual Studio development environment libraries and later blocked in Internet Explorer.

To eliminate this security risk, it’s recommended that users of versions 8.1, 8.5 and 14.0 switch to current, bug-free versions. The update announcement says updating will initially be optional, but will become mandatory for 8.1 and 8.5 in mid September, and for version 14 from the end of October. As the Windows Live Messenger Team explains in a blog entry eventually it will no longer be possible to log into Messenger using the older versions.

The security problem is triggered by Microsoft Visual Studio auxiliary libraries for creating ActiveX controls. Programs using these libraries are vulnerable. One can only hope that, in addition to Microsoft, other software vendors will follow the example of Adobe and Cisco and check their products as soon as possible.
