While surfing for stuff on Google with “sharecg.com” in the key words, came across a site which FF’s WOT had as Green.
I don’t know if anybody here has anything to do with WOT but if you do, kindly get it marked RED for iamnetizen. It’s an attack site.
Combing the computer I found 3 files which all appeared to be named the same ... as zip files. One in Downloads; and 2 others somewhere on the computer. I used W7’s search feature to find them. Although I have “show hidden extensions” these all appear to be as .zip files. They aren’t. The one in Downloads was an .exe and the other two were shortcuts to the ‘Net, calling home.
My AV flagged this as Trojan program HEUR:Trojan.Win32.Generic
As the apparent file extensions are bogus; the name to comb for and just delete them [do NOT click on them if you find them on your computer] is “daily_old_sharecg”.
