This is the first time I have posted here. I have had an issue on my computer for about a week. I noticed when my computer starts slowing or locking up that I get multiple copies of dllhost.exe *32. Whenever I notice these excessive processes I end them manually. When I notice this I have also noticed that the security settings in my EI get changed to a custom setting. I usually change it back to default as I am deleting the extra processes. I have Norton 360 on my computer and I have been getting a lot of messages that it is blocking an attempt by Trojan.adclick. I installed Malwarebytes (free version) and get almost constant popups that the program is blocking access from various websites. The most common of these websites is fff5ee.com but there are several including f0fff0.com. I have run scans with both Malwarebytes and Norton 360 but they are not detecting this problem.
I would really appreciate any help I could get on this topic as I am almost ready to start from scratch and re-install windows. I would rather not do this however as I am not sure I have all the software available to re-install that I have installed on my computer. All my software has been paid for but I am in the military and have moved a lot and am not sure I still have all the disks and license information readily available.
Thank you in advance for your help.
