In short order, I somehow got hit by Antivirus Soft. I didn't go so far as to fall for the "install this to save your computer!" thing, but I did have the pop-ups, the applications being blocked, etc. After a google search, I found a few somewhat similar methods of removing it, so followed one as closely as possible. The first step was to run MSCONFIG and stopped the startup item with the naming parameter that matched the Antivirus Soft .exe name:
Startup item: ouxhrllf
Command: C:\Users\El Juju\AppData\Local\spulnibhd\cstuifdtssd.exe
I was able to disable this startup item, as well as to locate and delete the .exe file. However the entry remains in my startup items (it shows as disabled, but it still shows) when I access them from MSCONFIG. This is my first concern regarding remnants of Antivirus Soft still being around. Is there a way to remove the entry from the startup list, and/or is its inclusion in the startup list (even as disabled) indicative of a problem?
Anyway, I continued to follow removal instructions, including correcting changes to connection settings (proxy settings) that Antivirus Soft had made.
I then ran scans with Avaste! (which did not catch it to begin with, it seems), Ad-Aware, MalwareBytes, Spybot Search and Destroy, and HijackThis. Everything has come back clean...which makes me think that something is off, given that practically nothing was done/removed besides the one startup item? I have read that there would be multiple registry entries to be deleted/repaired/whatever it is, but I was not able to locate any of these entries in my registry (followed the paths correctly from the examples given, but no sketchy entries were there)...so...I'm uneasy as to think that this is completely resolved.
I have run HijackThis. I will wait to post a log until someone asks me to, but my final concern regarding this whole matter is that 1. every time I run HijackThis, I get an alert from the program saying "For some reason, your system denied write access to the Hosts file. If any hijacked domains are in this file, HijackThis may NOT be able to fix this. If that happens, you need to edit the file yourself. To do this, click Start, Run and type:
"notepad C:\Windows\System32\drivers\etc\hosts" and press Enter. Find the line(s) HijackThis reports and delete them. Save the file as 'hosts'. (with quotes), and reboot." I tried to do this, but the file it generates is a generic file (I can post the contents of it if need be) that has no entries from any software, including HijackThis.
Finally, when the log is generated, there are over a dozen entries ("023 Service" entries) that end with the phase "(file missing)". This is the most frightening of all, even though I have no idea what I'm even looking at on this HijackThis log.
So to summarize-
1. Can I, and if so, how, remove that disabled entry from my Startup items?
2. Is there a program that can scan my registry specifically to look for/fix/delete any bad entries from Antivirus Soft? Do I need to do this?
3. Is my computer safe/clean?
4. What is the situation with all these items that say "(file missing)" in my HijackThis log?
I really really really really appreciate any help anyone can give me. Thank you.
