Scanning problems


I've been experiencing problems since the last update a couple of days ago.  My full scan takes literally about 3 minutes to complete, which surely cannot be right, and when I try a custom scan, i get the "An error has occurred" message.  I've tried the Virtual Technician, as well as a re-install combined with MCPR, but to no avail.  These seem to be the only issues.  I'm running WIndows XP Hom Edition Version 2002 and service pack 3.  Can anyone help?

Noticed that the right--click scan is completing far too quickly, too - not sure any of my scans are actually scanning anything.

Re: Scanning problems


To check this issue, first we need the version details of McAfee

Open McAfee > Go to About at the right top > Get the below versions

McAfee Security Center :

McAfee Virus scan :

DAT version:

Re: Scanning problems

Hi, Karthik,

thanks for replying.

McAfee Security Centre: 12.1

Anti-virus and anti-spyware: 16.1 (I'm guessing this is the same as Virus scan)

There is no listing for the DAT, though!  Is there another way to find it?

Re: Scanning problems

In 12.1 version we will not see the DAT version, alternatively you have Engine version and creation date of it.  Please update me the all the versions under McAfee Antivirus and Spyware.

Re: Scanning problems

Also check the DCOM Server Process Launcher service is set to automatic in the Service control manager window (services.msc)

Re: Scanning problems

The DCOM Server Process Launcher looks like its set to automatic.

I wasn't sure if you meant all the data under the Anti-virus and anti-spyware section or all the different section versions, i.e. Firewall, Siteadvisor, etc, so I've included both:

Anti-Virus and Anti-Spyware:

Version: 16.1

Build: 16.1.144

Last Update: 03/01/2013

Engine version: 1393.0

Creation date: 02/01/1013

Firewall: version 13.1

Siteadvisor: version 3.5

Anti-spam: version 13.1

Parental controls: version 14.1

Online backup: version 4.1

Quickclean and Shredder: version 12.1

Vulnerability scanner: version 2.1

Re: Scanning problems

I tried nearly all the suggestions with no luck, but I did notice that real-time scanning was off and wouldn't come on in safe-mode, is that normal?

The only one I haven't tried is checking the .dlls, as I when I try to 'Run as' there isn't an option to run as administrator - is this something I have to do in safe mode?  I only tried in normal mode.

Re: Scanning problems

In Safe mode you can’t turn on the real time scanning, it will be disabled, so no worries

Since you are using XP, you no need to use Run as Admin, directly open the command prompt and type Cd C:\Windows\System32 and hit ENTER

Then type the dll files and check it

Re: Scanning problems

Checked them and they all succeeded.  You originally had one of the dlls as 'Regvr32 vbscript.dll' I'm guessing you meant 'Regsvr32 vbscript.dll' as the command prompt didn't recognise it without the added 's'.  EIther way they all checked out.  I hope we're narrowing the problem down!
