Hi C69,
Just to add on to mchain's comment - the "corrupted" ZIP archives are almost certainly unrelated to the issues you are seeing.
The ZIP archive is corrupted error does not mean that the file is actually corrupted; it simply means that the scan could not unpack an archived file (and even if there is something malicious inside the archive, it will be caught as/when the file is unpacked by another program, as File Shield and/or Behavior Shield scan any compressed files that are unpacked in real time).
