Some downloads include a fake progress bar that looks like it is decompressing a large file, but it is actually installing malicious background processes. Incomplete Software:

| Software | Install Size | Best For | | :--- | :--- | :--- | | | ~150MB | Full compatibility with .docx/.xlsx | | SoftMaker FreeOffice | ~80MB | Interface very similar to Office 2010 | | AbiWord + Gnumeric | ~30MB total | Extremely old PCs (Windows XP/Vista) |

Any website that claims to offer Microsoft Office 2010 Highly Compressed 10mb with phrases like “100% Working,” “Cracked,” or “Activator Included” should be closed immediately. Run an antivirus scan if you have already visited such sites. Stay safe, and use legitimate software.
