I accidentally clicked on a link which turned out to be malicious. The link automatically downloaded a file called screenshot49.scr... I am not certain if this file was executed or not.. I didn't get any error messages. I have free photo editing software called Gimp, according to finder, the .SCR file is associated with this particular software as a config file.. I made a time machine backup a few days ago, should i restore just to be on the safe side? My virus software did not quarantine the file at all. I believe this is a Windows Screensaver, but I am just wondering if it would affect my machine running Yosemite. Thank you!
