Slow Pc And Had Found Powessere.d

My Windows 7 PC is set up with 3 accounts: an administrative account, a guest account and another one which my wife is primarily using. In the past I had used MBAM, AdwCleaner, Ccleaner, JRT, Rogue Killer and MS Security Essentials (so, yes, I used some programs you suggest to only run once some time before I came across your page Read Me first which I hope will not disqualify me from getting help).

During the month of May my computer started to be sluggish. I ran a couple of scans and cleaners and found some (what I remember to be) coupon printing software identified as spyware or adware (don’t remember). After that everything went well for a couple of weeks and things started to get slow again while online with Firefox (I looked at the task manager and found 65% CPU usage and over 2GB of Physical Memory in use without any obvious reason, but 0% network usage). I recall that AdwCleaner found something on 6/23 ( deleted file invalidprefs.js and a key delete in the registry). Also, since around this time, every time I log in with the admin account the desktop ikons are white tiles for up to 5-8 minutes and a window pops up twice “Catalyst Control Center Host application has stopped working”. I also discovered but didn’t see this until last week that MS Security Essentials found Behavior:Win32/Powessere.D which it quarantined and suggested to delete on 07/11. I deleted this a couple days ago.

Yesterday I uninstalled old (MBAM, AdwCleaner, Rogue Killer) programs downloaded them new (online) and ran (offline) the applications in the order you suggested and everything went well. However, Mgtools, also created two desktop.ini files after Mglogs.zip onto the desktop. Afterwards, four out of six times when shutting down the PC, it tried to Install Updates (1 of 1) even though it was offline. When looking into the error, I found updating “Advanced Micro Devices, Inc Driver Update for AMD SMBus” to have failed every time since 05/23. So, I went back online and performed Windows Update. No change to the performance or problems I am having or had though. I am worried that my PC may not be safe for things like online banking. Therefore I am asking for help and I am going to post the logs. I do have a couple old logs from June if needed.

Also, I am not sure if I am or if I was running too many (or the wrong) virus protection programs which may have or which are causing some of the issues I am having.

 

I apologize. I forgot to attach that file. I am attaching three files [S1] from 06/23, [S2] from 08/01 ans [S3] from today. I hope this is okay.
