My FSX dedicated system suddenly started suffering four very annoying problems:
1) Thread Creation / Thread Exit (almost any application) requires EXACTLY 30 seconds once every two minutes - i.e. a thread that is either created or deleted will take 30 seconds to return to the calling program - then for the next two minutes all other thread operations will respond normally - then after 120 seconds of normal (very quick) operation another (once only) thread creation or exit will require 30 seconds to complete. While the thread operation is waiting no IO and no CPU occurs for any thread associated with the mother process. The ONLY CPU or IO activity I see in the entire system during this long pause is due to Process Explorer or Process Monitor. However – IF I do start other processes during the pause – those processes run normally and quickly.
2) About half the time Firefox, Chrome, IE8, or IE9 URLs are redirected. When I boot the system the redirection may not occur for an hour or so and then starts up again.
3) At various times SAVE or SAVE AS goes 'non-responding'
4) Starting a Browser (any of them) sometimes results in a process (PE shows it using CPU and doing IO) but no displayable window. I must then cancel the Browser with ProcessExplorer
Event Monitor reports NO hardware problems
I ran (in the following order):
Windows Defender (current definitions)
MS Malicious Software Removal Tool (current definitions)
AFT Clean - reboot
Malwarebytes AntiMalware (MAM) (current definitions)
SuperAntiSpyware (SAS) (current definitions)
Only SAS found any problems (730) and then reported them removed. One threat was a Malware Trace and two were Security HiJack [Image File ExecuteOptions]. The rest of the threats were Adware in files – none were in memory nor in registry.
I rebooted, ran another scan and SAS reported no new infections.
All applications ran normally several hours. I flew a one-hour mission in FSX with 35+ fps and all sliders (except AI traffic) set to max – the system ran flawlessly the entire time
Then same problems as described above began again when I did some file operations e.g File Save or clicked on a folder to OPEN. I again ran SAS and it found 140 threats, which SAS removed. One threat was Security HiJack [Image File ExecuteOptions]. ALL other threats were in Adware in files – none were in memory nor in registry. I rebooted the system.
I ran the system for several hours and used most applications with no problem. I DID NOT connect to the WEB during any of that time. I put the system into a SLEEP state and returned two hours later. The first two file opens worked correctly and I then unzipped a file (scanned by Norton – the .zip had been on the system for over a year and I had unzipped it previously and installed that airplane into FSX) – that process ended with “not responding” and the problems then escalated as follows:
- SAVE or SAVE As or Unzip to any folder – window is shadowed and border says "not responding"
- Windows Task Manager replaces Process Explorer (I always have PE as the default TaskManager for ALT+CTRL)
- OPEN any file - "not responding" if I try to close window
- Thread Create / Thread Exit sometimes takes over 60 seconds during which time no other process or dll associated with the mother process gets a single CPU cycle
-Click on any desktop icon (start program or open file) - white screen for 30 seconds then returns to desktop -or- busy symbol for 30 seconds - Program never presents displayable window. NO CPU / Very little IO during that time - all by CPU done by Process=System
- Application (e.g. Hearts, WinWord, EXCEL) starts but there is no displayable window
MAM FULL SCAN reports NO Infections
SAS found 54 threats all Adware Tracking Code – all in Windows\System32\config\system profile\AppData\Roaming… MAM then removed all the threats – I rebooted and system ran OK for five minutes and problems began again – NO connection to outside world
Is this a virus / malware or a system problem?
