It all started a month ago. Got audio advertsiements (overlapping ads) coming out of the system even without browser on.
I cleaned it using Microsoft defender and Malware bytes few times, but keep reappearing. I keep cleaning but seems like it is a hidden virus somewhere deep in the system which get active again when I connect to internet or reboot.
Then noticed errors message popping up which say computer will shut down in few seconds..
Next stage was browser getting hijacked to rogue sites and intermittent audio ads playing in the back ground
I tried Spybot, MS security essentials, Malware, combofix ... No virus found. But didnt see issues found after one more round of clean up. I tried a trial version of ESET and it suggested rpcss.dll is infected (but unable to clean) as well as glrpack\aqreporter.dll
ESET deleted aqreporter.dll and now I am getting a pop error about missing dll.
(This is HP laptop with windows 7 Home professional, had previously made restore /repair disks, but didnt work when I tried..possibly bad CD's)
Some one please help ? I would like to clean the system if there are trojan still residing and also get the dll errors repaired.
By the way eset still send the message that rpcss.dll in the system32 library has a trojan. Thanks
