Avira Bug fix

[gilgalad]

hi,
I recently spent a lot of time in solving an anoying bug with Avira Antivirus, and i couldent find help across the net, so this is a bug fix instructions for the benefit of other users:

The bug:
Avira antivirus fails to start, the error massge is:
"missing Dll entry point Xbad@tr1@std@@YAXW4error_type@regex_constants12@@Z_? in MSVCP90.dll"
note: The MSVCP90.dll is related to visual studio.

The cause of the bug:
Recently I installed visual studio 2008 (C++) express. while debugging one of the my projects I suddenly had a visual studio crush. At that point Avira shot an error massage and shut down. From this point on the antivirus faild to start, nothing helped, including reinstalling Avira.

How I fixed the bug:
At the end I had no option but to remove Avira, then Remove Visual studio 2008 express, and the Visual studio 2008 Developers SDK.
Then I reinstalled Avira*, And checked that it is working fine.
After that I reinstalled Visual studio 2008**.

* after deleating Avira, i went into the registry (using "regedit") and deleted menualy all trace of "Avir". then I ran registry fix, of Adavance system care. - but I think theas two steps were not necessary.
** I had installed a different version of visuall studio, but again i do not believe it has any relevancy to the bug.

Good day all
