At seemingly sporadic times, there will be random ads sounding off in the background. I checked task manager and found Internet Explorer running in the 'Applications' tab, but no IE windows were present in my taskbar. In the 'Processes' tab, about 3-4 iexplore.exe would be running, with one that is consuming exceptionally high amounts of memory, from 50 K - 350 K. I am unable to 'end task' the IE application but i can temporarily stop the problem by ending all iexplore.exe process. However, after some time the problem reoccurs.
I believe the cause of this problem is due to a dupe Adobe Acrobat site that I was tricked into clicking to download the update just a day prior. Upon the completion of the download, my avast antivirus immediately notified me of the malware and then proceeded to block the infections by sending them to the virus chest. However, that did not seem to fully nullify the malware. I then restarted my computer as I did not want to click anything from the dubious prompts I was presented with. Afterwhich, I deleted whatever I had downloaded. I checked my control panel for any newly installed programs and found something called 'sursenel' that was installed/modified at the same time the virus was detected. However it was located in AppData which I believe to be essential files for the Windows OS, so I have not done anything to it for fear of data corruption. I used avast antivirus to scan that 'sursenel' folder and no threats were found. I have since then done a full system scan using avast antivirus but the only results I've gotten were that some files could not be scanned due to them being password protected and no threats were found otherwise. I have also gone to Control Panel -> Network and Internet -> Internet Options -> Advanced -> Reset IE settings but have not restarted my computer yet for the reset to take effect (the problem reoccured after I resetted but I have not done a computer restart, not sure if that will solve the problem at all).
Not sure how to proceed from here, would kindly appreciate any help I can get.
