HP Laptop, recently restored to Factory from Recovery Partition. Tried to install M'soft Security Essentials rather than use Norton. Failed with File Corrupt Error.
OS is Windows 7 Professional SP1 64bit
What I've done
1. Virus check using AVG, both from Windows and boot disk
2. Repair Install of Windows
3. Downloaded and installed all updates
4. Torn most of my hair out after trying to download and install countless times...
Any suggestions? Before I install AVG...(don't like being defeated!)
