Just thought I would post an update even though I have only done this so far:

Hard-Drive Maintenance/Repair:

Click on Start(Vista Orb).
Click on All Programs >> Accessories
Right click on Command Prompt and select Run as Administrator.
Click on Continue/Yes at the UAC prompt.
At the Command Prompt C:\Windows\System32> type in the following exactly:
CD C:\
Then depress the Enter/Return key, then type in the following exactly:
Now type in DEFRAG C: -F
A Analysis report will be displayed and then Windows will start the Defragmentation run automatically.


I assume it is still running and I have a feeling it will take a very long time. It's been running since this morning, though there was an interruption as I think as I hadn't turned off the auto-sleep mode (I think it may have paused while in sleep mode?). I recall trying to run a defragment a month or so ago but was put off when it said it would take over a day so I assume that's how long it will take.

The built in defragmenter does say it does a defrag every Wednesday and usually say's the last defrag was the previous Wednesday when I check, but I have always had a feeling that that is not actually the case.

In any case, I shall get back to you again once everything is finished but I just thought I would let you know it could be a while.

If the defrag' run does appear to be taking a excessive amount of time merely halt it and proceed to the check-disk onwards and we can defrag' later on etc. :)

The defrag was taking a bit too long so I decided to stop it and proceed like you said.

Here is the log:

C:\ProgramData\Spybot - Search & Destroy\Recovery\YontooPagerage5.zip Win32/Bagle.gen.zip worm
C:\Users\All Users\Spybot - Search & Destroy\Recovery\YontooPagerage5.zip Win32/Bagle.gen.zip worm
C:\Users\Ally\Documents\Handkerchief\CLASS.EXE probably a variant of Win32/Agent.FTPPIGI trojan
C:\Users\Ally\Downloads\Handkerchief.rar probably a variant of Win32/Agent.FTPPIGI trojan
C:\Users\Ally\Downloads\Pazera_Free_MP4_to_AVI_Converter.exe Win32/InstallMonetizer.AF application
C:\_OTL\MovedFiles\01032013_163240\C_ProgramData\dsgsdgdsgdsgw.js JS/Agent.NID trojan


I can't help but notice it mentions Handkerchief. I know this to be safe as it is actually a really obscure game. Just thought I would mention that.

Hi. :)

I can't help but notice it mentions Handkerchief. I know this to be safe as it is actually a really obscure game. Just thought I would mention that.

That is fine and what is known as a false positive detection as is the Pazera. Overall no action is required with regard to the online scan results, two are quarantined by Spybot and the the OTL one will be fully removed when we clean up tools used etc.

The defrag was taking a bit too long so I decided to stop it and proceed like you said.

Fair play, I am surmising the Check Disk completed, so try a defrag' again, if still a problem run another Check Disk then try a defrag' again etc.

Next:

Let check/update some software as follows shall we...

  • Download and install FileHippo Update Checker from here.
  • Once installed(during the installation process deselect the option:- Run at Startup >> Start(Vista Orb) >> All Programs >> right-click on Update Checker and select Run as Administrator >> a browser window will open after the scan is complete.
  • Download any updates detected(apart from beta updates) to the desktop >> uninstall anything that requires updating via Programs and Features in the Control Panel.
  • Re-install the updated software, delete the installers and then empty the Recycle Bin.
  • When completed the above let myself know and if any further issues remaining, thank you.
Note: When I give the all clear my advice would be to consider keeping FileHippo Update Checker installed. Then periodically use it to check for any updates as having certain software outdated is a potential for malware to gain a foothold and exploit a system etc.

Yeah Check Disk completed ok.

I updated everything that needed updating and everything seems to be running fine at the moment. Still need to defrag but I put that off for now as it's likely to take a long time so I thought I would get everything else out the way first. I only work weekends so it's a lot easier for me to do it during the week when I can monitor throughout the day.

Hi. :)

OK fair play RE what you mentioned about a defrag'...

Next:

Congratulations your computer appears to be malware free!

Now I have some tasks for your good self to carry out as part of a clean up process and some advice about online safety.

Importance of Regular System Maintenance:

I advice you read both of the below listed topics as this will go a long way to keeping your Computer performing well.

Help! My computer is slow!

Also so is this:

What to do if your Computer is running slowly <-- This link is currently off-line but should be back up in due course.

Clean up with OTL:

  • Right-click one OTL.exe and select Run as Administrator to start the program.
  • Close all other programs apart from OTL as this step will require a reboot.
  • On the OTL main screen, depress the CleanUp button.
  • Say Yes to the prompt and then allow the program to reboot your computer.
The above process should clean up and remove the vast majority of scanners used and logs created etc.

Any left over merely delete yourself and empty the Recycle Bin.

Reset the System Restore points:

Create a new, clean System Restore point:-

  • Right click on Computer and select Properties >> System protection >> Create.
  • Give this restore point a descriptive name and click on Create.
  • When the new restore point is created click on OK >> close the System Properties window.
Note: Do not clear infected/old System Restore points before creating a new System Restore point first!

Flush Old System Restore points:-

  • Next click Start(Vista Orb) >> Run (or the Windows key and R together) to bring up the Run box and and copy and paste in:
    cleanmgr
  • in the box and press OK.
  • Select the system drive, C >> OK.
  • Ensure the boxes for Recycle Bin, Temporary Files and Temporary Internet Files are checked, you can choose to check other boxes if you wish but they are not required.
  • Click on Clean up system files >> Select the system drive, C >> OK.
  • Now click on the More Options tab.
  • Under:-
  • System Restore and Shadow Copies
  • Click on Clean up... >> Delete >> OK >> Delete Files.
Now some advice for on-line safety:

Malwarebyte's Anti-Malware:

This is a excellent application and I advise you keep this installed. Check for updates and run a scan at least once per week.

Other installed security software:

Your presently installed security application, avast! Free Antivirus automatically checks for updates and downloads/installs them with every system reboot and or periodically if the machine is left running providing a internet connection is active.

I advise you also run a complete scan with this also at least once per week.

Erunt:

Emergency Recovery Utility NT, I advice you keep this installed as a means to keep a complete backup of your registry and restore it when needed.

Myself I would actually create a new back up once per week as this along with System Restore may prove to be invaluable if something unforeseen occurs!

Keep your system updated:

Microsoft releases patches for Windows and other products regularly:

  • Click on Start(Vista Orb) >> All Programs >> Windows Update.
  • In the navigation pane, click Check for updates.
  • After Windows Update has finished checking for updates, click View available updates.
  • Click to select the check box for any found, then click Install.
  • When completed Reboot(restart) your computer if not prompted to do so.
Be careful when opening attachments and downloading files:

Never open email attachments, not even if they are from someone you know. If you need to open them, scan them with your antivirus program before opening.
Never open emails from unknown senders.
Beware of emails that warn about viruses that are spreading, especially those from antivirus vendors. These email addresses can be easily spoofed. Check the antivirus vendor websites to be sure.
Be careful of what you download. Only download files from known sources. Also, avoid cracked programs. If you need a particular program that costs too much for you, try finding free alternatives on Sourceforge or Pricelessware.

Stop malicious scripts:

Windows by default allow scripts (which is VBScript and JavaScript) to run and some of these scripts are malicious. Use Noscript by Symantec or Script Defender by AnalogX to handle these scripts.

Avoid Peer to Peer software:

P2P may be a great way to get lots of seemingly freeware, but it is a great way to get infected as well. There's no way to tell if the file being shared is infected. Worse still, some worms spread via P2P networks, infecting you as well. My advice is avoid these types of software applications.

Hosts File:

A Hosts file is like a phone book. You look up someone's name in the phone book before calling him/her. Similarly, your computer will look up the website's IP address before you can view the website.

Hosts file will replace your current Hosts file with another one containing well-known advertisement sites, spyware sites and other bad sites. This new Hosts file will protect you by re-directing these bad sites to 127.0.0.1.

Here are some Hosts files:

Only use one of the above!

Consider installing WinPatrol:

WinPatrol alerts you about possible system hijacks, malware attacks and critical changes made to your computer without your permission.

Download it from here.

You can find information about how WinPatrol works here.

Next:

This is a very helpful/useful set of advice from Microsoft: Microsoft Safety & Security Center

Any questions? Feel free to ask, if not stay safe!

Right, that's all done. Everything seemed to have gone well.

Thank you for all the help and all the great advice, I think I will be bookmarking this for future reference. :)

I do have to note one slight concern however. I just checked how much space I had free by right-clicking the C: Drive in the Computer folder and it say's I now have 622gb free and have used up only 308gb. Obviously the more free space the better, I was just shocked at how much more free space I had after doing the last steps from your previous post. Is that normal? I used to have around 426gb used up at least, but if it's normal then that's cool.

This is absolutely fine and not a cause for concern. This would have occurred after performing the Reset the System Restore points advice, which also would have flushed the Vista Shadow Copies. Further information about this and how to adjust the allocation can be read at the below article:-
