navexcel.xlam

Hi there, I have NOD32 installed on my PC but I have got the navexcel.xlam virus/malware/trojan now... Everytime I try to run Microsoft Excel, I get a window saying 'This file is not in a recognizable format' If I click OK, Microsoft Excel opens but with a page of strange characters displayed.

How can I get rid of this? Does Nod32 not remove this?

 

It sounds like the file got corrupt, not necessarily by malware.

 

I have removed Microsoft office and re-installed it again and this problem with navexcel.xlam still exists....

any ideas?

When I run a virus scan, it doesnt detect anything?

 

upload the file in question to virustotal and see the results there as well as submit it to Eset for analysis, to figure whether it is real threat or a false positive

 

It sounds like Excel is trying to load something at startup.

With Excel closed, try renaming the 'XLStart' folder in each of these two locations:

C:\Program Files\Microsoft Office\Office12 *
(*note it may be Office 12,13 or 14 depending on your version of Office).

and

C:\Documents and Settings\User_name\Application Data\Microsoft\Excel\ (for Win XP)

or C:\Users\User_name\Appdata\Roaming\Microsoft\Excel (for Vista/7).


Also check that no other folders have been set as Excel startup folders, by going to the Office button or File tab > Options > Advanced > General > check that 'at startup load all files in' is blank.
