McAfee false positive detection of w32/wecorl.a when using 5958 DAT file

McAfee has identified an issue where a specific DAT file version is causing a false positive detection of the w32/wecorl.a virus. When this false positive occurs, Svchost.exe is blocked and quarantined, which will cause the machine in question to shut down with a DCOM error, and can in some circumstances cause a blue-screen. This issue appears to only occur on Windows XP SP3 clients.

This issue is known to occur with version 5958 of the McAfee DAT file, released on April 21, 2010. McAfee has released an EXTRA.DAT file to suppress this false detection. After installing the EXTRA.DAT, you can restore the effected file from Quarantine within McAfee. To restore a file from Quarantine, please carry out the following steps:

1. Open the VirusScan Console.
2. Double-click Quarantine Manager Policy.
3. Click the Manager tab.
4. Right-click the required item and select Restore.

For more information, please refer to the following McAfee articles:

Cheap free internet hotspot gateway

I was given a task by our upper management to setup a free wireless access on our remote locations. I have been searching for an appliance or software that can provide a splash screen for end users to see to agree on the Terms of Use. I first look at nomadix which I know is popular but very expensive. I also tested the zone cd which was very easy to set up but there was a recurring cost. So I went ahead and tested antamedia hotspot software which really work well and very easy to configure even the splash screen was easy to customized. The caveat to this is that you still need a PC with dual NICs for it to work and it will cost you around $400 just for the software not including the PC. I was determine to get this software but when we were ready to get it, we had issues paying for it because we only do purchse orders not credit cards plus the company is not in the United States. It was a blessing in disguise that this company that I called before ( finally got back to me and told me that a new box just came in. I went ahead and ordered it and when I got the boxes it literraly took me less than 15 minutes to set it up with terms and conditions with customized splash screen. The box looks like a small router that runs on unix. The best part, It only cost us $190.00 per box without the need of another PC.
