Ever heard that Macs don't get viruses? Don't believe the rumor!
We've recently encountered a particularly malicious form of malware that targets Apple computers. The Trojan Horse poses as a download to fix a Quicktime issue with the message "Quicktime Player is unable to play movie file. Please click here to download new version of codec." If you see this message, do NOT click the link. It will download a Trojan Horse to your computer and removal of the trojan generally requires reformat of the computer. You can read more about it here: http://www.intego.com/news/ism0705.asp.
What can I do to protect my Mac? Security for Macs is very similar to security for PCs. Columbia University offers a free copy of Symantec Anti-Virus for both Macs and PCs. Check our Downloads Page for more information. Mac users should download Symantec and set up weekly scans. In addition, always make sure that you have backed up important data (especially that thesis draft!). See our Backing Up Page for more information and instructions. If you encounter any trojans, viruses, or other forms of malware, or if you need help backing up data, please come into the LCC to see an ACE during our Office Hours.
Many students use MS Powerpoint to aid with presentations for classes and activities. A common issue that students have been asking about lately is that images and video added on a Mac don't show up on PCs. Mac users can drag and drop images into Powerpoint. However, when opening the presentation on a PC, images that have been dragged and dropped will show up with the error message similar to "QuickTime(TM) and a TIFF decompressor are needed to see this picture." Even if you have Quicktime installed, the files will not show up on a PC.
How to fix the problem:
For Image Files, save the image file in a convenient location on your computer. Select "Insert," then select "Picture," and then select "From File." Browse your computer to find the image file and insert! This should solve the problem.
Video files present a slightly more complex challenge. Follows these steps to add video files:
