hi , “People that have removed the user32.dll can either boot from their original Windows CD and choose the repair option, or use another CD to boot from and restore the file from C:WindowsSystem32dllcache. If you happen to need a bootable CD: my personal favorite is the Ultimate Boot CD”

i have this boot cd and need to restore uer32.dll, how would i do this?! , thanks

was using avg before and was updating with no problems then it ran out.
I installed mcafee, didn’t like it.
reinstalled agv, did update & it started attacking those windows files.
Formated drive and installed image from early last year installed mcafee, updated it & started doing XP updates from the update site, they failed to install & said i should reboot & try again. When it was shutting it showed the same system file it showed when it had the avg problem & avg hadn’t been on the drive since the format & image setup.

So this bug must include an issue that effects bios or something else.

Has anyone got any ideas.

I can’t thank you enough!

I was desperately trying to fix this issue for someone, and had tired pretty much everything short of reinstalling Windows.

This was on a Greek machine and occured only about a week ago.

I dont think it is fixed yet.
I installed 7.5 a week back..The first thing it did was to look for “Latest Update”. Down loaded them and after that I ran the scanner. It deleted not just one .dll but very many and made my system un-bootable.
C:\WINDOWS\system32\cabinet.dll
C:\WINDOWS\system32\imm32.dll
C:\WINDOWS\system32\msimtf.dll
C:\WINDOWS\system32\msvcr71.dll
C:\WINDOWS\system32\psapi.dll
C:\WINDOWS\system32\riched20.dll
C:\WINDOWS\system32\uxtheme.dll
C:\WINDOWS\system32\wsock32.dll
C:\WINDOWS\system32\xpsp2res.dll
C:\WINDOWS\system32\rundll32.exe
C:\WINDOWS\system32\shell32.dll
On the web site it had a fix. But the fix was to fix the files if you have quarentined them. The web is quiete and avoided any solution, not even mention, what you are supposed to do if the scanner has deleted the files. I removed the affected HDD, connected it as external drive to another computer. Searched for AVG’s log file, got the list of files deleted and copied them back from another system. Booted in safe mode, and did a restore point recovery.
Took almost a week for me to do all this. ]]>

Funny how this came out on the 11th Nov, but this problem isn’t fixed!! I bought a new laptop on the 20th Nov, that
had AVG installed… I updated the virus definitions and then gave me the warning…. It removed several files and now won’t boot. And I’m using english Win XP Pro.
Once I have this sorted I’ll permanently delete AVG – what a load of crap!! ]]>
