Also my Symantec is reporting that comboFix is a trojan. Is it possible that it can get infected?

That's normal. No worries.

• Click on to download the ESET Smart Installer. Save it to your desktop.
  
• Double click on the icon on your desktop.
  

•Check
•Click the button.

•Push , and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
•Push the button.
•Push
A log file will be saved here: C:\Program Files\ESET\ESET Online Scanner\log.txt

My computer looks fine and working very smooth right now.

Its only my Symantech is reporting threats from ComboFix quarantine folder.
I just finished 18 hour long ESET scan and nothing found in that scan.

Thank you so much for the help. Please let me know what steps needs to be done next. Also please provide your personal donation link in your next post.

Please suggest which is the most trusted Antivirus or Malware protection software/tool should I use to avoid this hassle in the future.

That's normal. We'll get rid of those right now.

I don't have one but there could be one on this site.

Please suggest which is the most trusted Antivirus or Malware protection software/tool should I use to avoid this hassle in the future.

Below you will find a list of free AV's. I prefer MSE but everyone has different opinions. I like MSE because it's lite-weight, not a resource hog like some, no hassles installation and updates every day.

Remember to only install one antivirus!

1) Avast! Home Edition
2) AVG Free Edition
3) Avira AntiVir Personal
4) Microsoft Security Essentials for Windows Vista\Windows 7 - 64 bit Download
4-a) Microsoft Security Essentials for Windows XP
5) Comodo Antivirus (Uncheck during installation "Install Comodo SafeSurf..", Make Comodo my default search provider" and "Make Comodo Search my homepage" if you choose this one)
6) PC Tools AntiVirus Free Edition
7) ThreatFire

It is strongly recommended that you run only one antivirus program at a time. Having more than one antivirus program active in memory uses additional resources and can result in program conflicts and false virus alerts. If you choose to install more than one antivirus program on your computer, then only one of them should be active in memory at a time.
********************************************************
To uninstall ComboFix

• Click the Start button. Click Run. For Vista: type in Run in the Start search, and click on Run in the results pane.
  
• In the field, type in ComboFix /uninstall
  

(Note: Make sure there's a space between the word ComboFix and the forward-slash.)

• Then, press Enter, or click OK.
  
• This will uninstall ComboFix, delete its folders and files, hides System files and folders, and resets System Restore.
  

*************************************************
To remove all of the tools we used and the files and folders they created do the following:
Double click OTL.exe.

• Click the CleanUp button.
  
• Select Yes when the "Begin cleanup Process?" prompt appears.
  
• If you are prompted to Reboot during the cleanup, select Yes.
  
• The tool will delete itself once it finishes.
  

Note: If any tool, file or folder (belonging to the program we have used) hasn't been deleted, please delete it manually.
*************************************************
Clean out your temporary internet files and temp files.

Download TFC by OldTimer to your desktop.

Double-click TFC.exe to run it.

Note: If you are running on Vista, right-click on the file and choose Run As Administrator

TFC will close all programs when run, so make sure you have saved all your work before you begin.

* Click the Start button to begin the cleaning process.
* Depending on how often you clean temp files, execution time should be anywhere from a few seconds to a minute or two.
* Please let TFC run uninterrupted until it is finished.

Once TFC is finished it should restart your computer. If it does not, please manually restart the computer yourself to ensure a complete cleaning.
**************************************************
Looking over your log it seems you don't have any evidence of a third party firewall.

Firewalls protect against hackers and malicious intruders. You need to download a free firewall from one of these reliable vendors.

Remember only install ONE firewall

1) Comodo Personal Firewall (Uncheck during installation "Install Comodo SafeSurf..", Make Comodo my default search provider" and "Make Comodo Search my homepage" and uncheck any HopSurf and/or Ask.com options if you choose this one)
2) Online Armor
3) Agnitum Outpost
4) PC Tools Firewall Plus

If you are using the built-in Windows XP firewall, it is not recommended as it does not block outgoing connections. This means that any malware on your computer is free to "phone home" for more instructions. Simply put, Windows XP contains a mediocre firewall. This firewall is NO replacement for a dedicated software solution. Remember to use only one firewall at the same time.

Use the Secunia Software Inspector to check for out of date software.

•Allow the scan to finish and scroll down to see if any updates are needed.
•Update anything listed.

Hi Dave,

I tried cleaning up using above steps but I can still see all the software: Mbam, sysprot, SuperAntiSpyware, SecurityCheck, TFC, aswMBR are still present at my desktop.

Also command "ComboFix /uninstall" didn't run for me. I tried all the combinations too.

There is also one more wired behavior at startup. I see 2 text files being open up every time my computer restarts.
Screen shot is attached:

Let me know how can we fix it.

There is also one more wired behavior at startup. I see 2 text files being open up every time my computer restarts.

I've never seen this before. Is this the first time this has happened?

That started happening after I ran ComboFix for the first time long back. If I remember correctly my laptop got hang and I had to force reboot my laptop while combofix was in process to clean my laptop. And after that I see those 2 files open everytime my laptop reboots.
