Boggin:
Reading a HJT log is a specialized op as there could be entries that only a security expert could recognize as being malicious, but going from the other malware scans, it would seem that your system is clean and that it's my belief that it's Avira that has caused the corruption.
If you can reinstate those files then I'd dump Avira for something else.
It's possible that an offboot sfc /scannow will replace those files if they remain corrupt and for that you would need an appropriate bootable Win 7 SP1 install USB/DVD.
You can download the appropriate ISO from http://www.w7forums.com/threads/official-windows-7-sp1-iso-image-downloads.12325/page-2#post-124821 and you can use http://www.microsoft.com/en-us/download/windows-usb-dvd-download-tool to create a bootable USB/DVD.
To save me some typing, I've already given instructions in how to boot up with the bootable media and perform the offboot sfc /scannow in Reply #3 in this thread which you can follow http://www.tweaking.com/forums/index.php/topic,2709.0.html
Boggin:
I don't know if those missing DLLs would have affected System Protection and your restore points if you have them enabled, but Windows Updates would have created a restore point prior to their install, so it is of concern that you don't have any.
Shane will know more about the role of those DLLs but he won't be back until Monday - his day job permitting.
Shane:
Those dll's are on my system as well, and in both system32 and syswow64 folders. They are suppose to be there.
Any update since these last posts?

hi,
well yeah i restored those dll from avira quarantine and it worked! everything seems to work great again
but sfc scannow still give me some errors so i think im going to todo one sfc scannow with win 7 media
i think ccleaner deleted my restore points and windows update cache too so this with avira epic fail did this.
Boggin:
Glad you were able to dig those files back out of quarantine.
I use CCleaner and it's never removed my restore points but it could be because of corrupt files that sfc /scannow has found, although missing restore points has been an on going problem with Win 7.
The first article lists some Event Viewer Error Event IDs to look out for and the second, some suggestions to try and resolve the problem, but a Google for missing restore points in win 7 will produce a number of links where others have experienced the same problem.
