Virus' entered my computer with Lightroom download. I recently had my computer wiped and rebooted at a professional IT store. First thing I did when I got it back was install AVG then purchase creative cloud Lightroom and Photoshop for $9.99. (I know AVG is possibly not the absolute best software available but I have never had any trouble using it) The creative cloud installed fine and automatically started downloading lightroom, as it said it would. As soon as the lightroom instal started AVG detected 11 virus/bugs etc. I had them all destroyed but some got through undetected. As soon as my lightroom and photoshop were installed I went online and started being attacked by pop ups especially Royal Raid Ads. I googled these and it said that they sneak in with legitimate downloads. I googled how to fix this, told me to enter safe mode on my computer, do a disc clean (which was easy as my computer is completely empty atm) and then I used a Kaspersky virus removal tool. I did this and it found 4 virus hidding amoungst the Adobe Lightroom programs. I had these destroyed by the virus removal tool. So far it looks to have worked thank goodness!!
