Still Having Problems (Combofix took forEver & did something odd)

Okay, my laptop has been sluggish for a while from time to time when I was in Firefox or had Firefox, Last.fm, and TweetDeck open at the same time, but I always thought it was because
1. the low connection to our wireless router
2. too many memory hogs open at once
3. Firefox doing its crash thing (it crashed on me every now and again, and the other 2 soon followed)

My father has also been having trouble with a sluggish computer, but Mom and I just assumed it was because he got impatient and kept clicking and clicking on things in his frustration when things didn't immediately happen.

We-e-ell, he and Mom both had trojans come up on their Malware Bytes scans. I hadn't run that on my laptop in quite some time, so I did, and it came up fine. Then, I started getting funky messages like my firewall had a fatal error and needed to close or some such.

Also, as I was dinking around your downloads for something else, I spotted that your pick for antivirus software was PCtools, and I thought to myself that it was probably better to have the same antivirus as I do firewall, so I downloaded that, uninstalled Avast!home, and installed PCTools antivirus. I also installed Threatfire beta, but I have since uninstalled that. I was going to reinstall that, but my system seems to be running more happily without it, so I'm not going to.

Anyway, after I installed PCTools antivirus, things just went all to hell. I started getting all kinds of messages about how there was a new update for it (even though I had just updated it), and once I had downloaded the update, I got a message saying my computer had to restart in order for the update to be installed. Then when my computer came up, it didn't get past the wallpaper coming on (no icons or taskbar). It brought up the taskmanager when I did ctrl+alt+del, though, so I was able to shutdown that way.

I ran SAS, and it found 2 occurrences of a trojan called FAKE.ALERT, and I thought "a-ha!" I took care of that, and then I uninstalled Firefox (because it said used rarely in my program list) and went directly to the site (instead of doing the update through the program) and downloaded it and installed it. I then uninstalled PC Tools antivirus and went directly to the PC tools site and downloaded it from there and reinstalled it. It found 2 trojans (3, actually, but one of them was Combofix, so I ignored that) after not finding anything all the other times I'd run it.

I ran SAS, MBAM, Combofix, RR, and MGTools, and I am still having troubles with PC usage going up to 100% when only 1 thing is open, funky error messages like "spooler subsystem has been shut down to protect your computer from potential risk," or something like that, and just generally odd behavior. Plus, like I said in the heading, Combofix took a lo-o-o-ng time to finish, like maybe 15-20 minutes minimum, and during stage...4, I think it was...it printed out this funky thing that looked like the "about" page for some kind of software. *scratches head*

Oh, and I've lost my job, so...no rush anymore, other than...it's National Novel Writing Month and this is my writing computer. *bites nails*

Thanks, folks!

Um...It won't let me post my Root Repeal log, no matter what I name it. It says I already posted it with one of my previous posts. I did post RRlog, but I didn't post it under another name.... Is there a way you can delete that from that post or something? Or, if the file is identical, maybe you don't need to. I guess I'll just go ahead and post MGlogs to this since RRlog won't attach.

 

Yep, already noticed and did so.

Odd. Okay, I did as instructed. All of it. Hope it all works better this time. MGLogs.zip attached.

Thanks for responding so quickly! :wave
