Hello to everyone, new user here. I wasn't sure which is the right board for this as this is kind of a newbie problem but not probably (hopefully?) one that should be in "viruses and worms" section. I've been without AV for a while, using Windows Defender and Windows Firewall after my last AV expired and soon after also Malwarebytes. I'm using Windows XP on desktop PC.
Now I'm using Malwarebytes free version, and today I installed PrivateFirewall and avast! AV free version. I did a quick scan on Malwarebytes and startup scan on avast!. I also did a Boot-time scan (25 infected files detected and deleted).
I've got two problems with avast! for which I couldn't find a solution by myself or via google.
Firstly, when I click "More detail..." or other such that opens a page in web browser it fails to do so. I once tried to remove Internet Explorer following Microsoft's own instruction but it didn't work completely, as now avast! tries to open the page in IE and fails (I see a flash of IE and then nothing happens). Couldn't find a way to change the browser in avast! settings either. Firefox is my default browser.
Secondly, I get continuing pop-ups from avast! (every few minutes, sometimes several per minute) saying "malware blocked" or "malicious url blocked" (I've got File System, Web, Network, Script and Behavior shields). Now, I'm not sure if this indicates that there's a problem or if this is normal. If latter though, then my problem is that I can't find a way to stop these pop-ups except choosing the "Silent/Gaming mode" in which case none of the other pop-ups show up either. I tried changing the duration the pop-ups stay visible to 0 seconds, but it didn't work.

Could you attach a screenshot of the Avast alert please

You would be best to attach this file

Attach the files do NOT copy and paste.

Makes sense. Sorry, not accustomed to forums. There was another topic (perhaps a different forum) where there copy/paste was used so I just stupidly followed the example.

Not a problem. :)

OK this may take a few runs to tidy up properly. First you will need to remove Norton.. Use the removal tool here https://support.norton.com/sp/en/uk/home/current/solutions/kb20080710133834EN_EndUserProfile_en_us
THEN

avast! has given a warning on this several times: "File: system32\drivers\volsnap.sys Rootkit: Win32:Alureon-PS" and recommends that I remove it and every time I've clicked remove. Afterwards when I scan it with avast! and Malwarebytes they find the file clean.
After the fix on OTL the filetype's became visible after the filenames (textfile.txt, magazine.pdf etc.) though I had chosen to hid them, although I doubt this is relevant.
And in case it matters, here's the other kind of warning avast! has been giving me:

The text file on the quick scan attached.

"File: system32\drivers\volsnap.sys Rootkit: Win32:Alureon-PS"

Should I have gotten the report before rebooting? I got it after, hope that doesn't matter. Attached.
Right after the scan (and cure) before the reboot I got this message from avast!:

There should be a larger log at C:\TDSSKiller date time could you attach that please, Avast alerts should have now ceased
-
Yes, no more alerts since. The log was a several folders and text files, I copied the text files and locations in one text file. Attached. There was also tsk0001.dta -file. Do you want me to upload it for you?
Should I keep any of these programs you had me download? If not, how do I go about removing them? Do I just delete them normally, and what about the folders in C:\?
-
I will tidy up for you as soon as you are happy :) How is the computer behaving now, any further problems ?
-
There hasn't been a single warning popup from avast! since yesterday. I see no problems and overall my computer is running more smoothly than in months. I couldn't be much happier :D
This is the first time anyone's been so helpful when I've had problems. Thank you so much for your help!
-
Subject to no further problems :)
I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems
Now the best part of the day ----- Your log now appears clean :thumbsup:
A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset System Restore points:
Run OTL- Under the Custom Scans/Fixes box at the bottom, paste in the following
:Commands
[resethosts]
[emptytemp]
[CLEARALLRESTOREPOINTS]
[Reboot]
- Then click the Run Fix button at the top
- Let the program run unhindered, reboot the PC when it is done
Run OTL and hit the cleanup button. It will remove all the programmes we have used plus itself.
: Keep Java Updated :
WARNING: Java is the #1 exploited program at this time. The Department of Homeland Security recommends that computer users disable Java
See this article (http://www.forbes.com/sites/eliseackerman/2013/01/11/us-department-of-homeland-security-calls-on-computer-users-to-disable-java/) and this article (http://www.nbcnews.com/technology/technolog/us-warns-java-software-security-concerns-escalate-1B7938755).
I would recommend that you completely uninstall Java unless you need it to run an important software.
In that instance I would recommend that you disable Java in your browsers until you need it for that software and then enable it. (See How to diasble Java in your web browser (http://www.geekstogo.com/2600/how-to-disable-java-in-your-web-browser/) and How to unplug Java from the browser (http://krebsonsecurity.com/how-to-unplug-java-from-the-browser/))
Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:
Malwarebytes (http://www.malwarebytes.org/mbam-download.php).
Update and run weekly to keep your system clean
Download and install FileHippo update checker (http://www.filehippo.com/updatechecker/) and run it monthly it will show you which programmes on your system need updating and give a download link
If you use on-line banking then as an added layer of protection install Trusteer Rapport (http://www.trusteer.com/Products/Trusteer-Rapport-for-Online-Banking)
It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit - Microsoft Windows Update (http://windowsupdate.microsoft.com)
To learn more about how to protect yourself while on the internet read our little guide How did I get infected in the first place ? (http://www.geekstogo.com/forum/topic/225044-preventing-malware-and-safe-computing/)Keep safe :wave:
