I think that's Google Chrome's virus warning page, not an antivirus program. Nonetheless, the cause is still the same: an image will be from an 'unsafe' site.# Edit: yes it is, if you go to http://macrobellstore.com/ Google Chrome detects 'malware'. In the picture in OP you can just make out that an 'element' on the page is from macrobellstore.com.
