Hi - looks like I've got a similar issue as other posters regarding dllhost.exe*32 com surrogate. The OS is Windows 7 Home Premium - Service Pack 1 - 64-bit.
The computer slowed down significantly a couple of days ago, along with pop-ups in IE asking if I wanted to debug the page. Then I started getting the "powershell stopped working" pop-up whenever I booted up, as well as a pop-up saying I should close all programs due to high memory usage.
The latest issue occured today, where I turned it on and got multiple pop-ups about the powershell not working, along with notepad opening by itself and then a Firefox shortcut being created on my desktop called "DECRYPT_INSTRUCTION" (https://paytordmbdekmizq.torsona.com/7UUps6), which I did not open. Also, I had ran my AV (McAffee - Version 6.0.3 Patch 3), which found about 50 files all called "Ransom-Foo!htm" all of which were quarantined.
I can see 2 dllhost.exe files in Task Manager, along with dllhost.exe*32 com surrogate. There also appear to be several other .exe and .exe *32 files that don't seem right to me (I'm nowhere near an expert, but from reading other posts here it sounds as if these items could be suspicious as well).
I appreciate any help you can offer, and if you need any other information please let me know. Thanks!
