I had several problems with my laptop and at somepoint I couldn't even get into windows.
I installed avast and started getting weird virus messages (I had AVG before). I run a Malwarebytes' Anti-Malware scan that found 79! infected files. Deleted all of them.
I now can't update to SP3. It starts with preparing to download and then it says that it failed. I tried a solution I found here with turning off and on automatic updates. Also tried the long version of it. No luck!
Also, can't update avast now. I try running it manualy and I get an error message
"...avast.setup has encountered a problem and needs to shut down..."
Problem signature as follows:
AppName: avast.setup AppVer: 18.104.22.168 ModName: ntdll.dll
ModVer: 5.1.2600.2180 Offset: 0001302c
I have completely uninstalled and reinstalled avast. No luck
