Exterminate It! Antimalware


Known threats:700,085 Last Update:March 01, 12:55


I consider myself pretty good with a computer, but after 10 hours of trying to do this myself, the sysguard.exe whipped me. I couldn't find all the files and when I thought I had them all, they would replicate and play hide and go seek I have never endorsed a product in a comment, but if you want to rid yourself of this stuff, pay the $24.99 and download Exterminate-It It fixed my system in 5 minutes!
