I had doubts whether my computer was infected with malware and I downloaded Combofix and ran it. The problem is I missed reading the instructions given on using Combofix. I downloaded it to 'my documents' folder and ran it.

There is no problem with my computer now but I wanted to know whether it would be safe to uninstall Combofix at this stage. Please advise. I have read online how to uninstall Combofix. I am attaching the log. Please can you say if there is any problem.

I work as a virtual assistant and I don't want my work to suffer if something happens to the computer and it stops working.

Please advise.

Thanks,

Uma

I don't see anything in your log that looks bad.

Since you have Avast I suggest you run a boot-time scan periodically:

Click on the Avast ball. Then click on Scan Computer, then on
Boot-Time Scan then on Settings. Change the Ask at the bottom to Move to Chest. OK then Schedule Now. Reboot and let it run a scan. It will take hours.
Once it finishes it should load windows. Click on the Avast ball and then on Scan Logs, select the Boot-time scan report then View Results. How many did it find?

To uninstall Combofix:

Copy the next line:

f:\my documents\Downloads\ComboFix.exe /uninstall

then
Start, All Programs, Accessories, Command Prompt. Right click and Paste or Edit then Paste and the copied line should appear. Hit Enter.


You probably do not have the latest Java (Java™ 6 Update 30 or 7 update 2). Get the latest at:
http://www.java.com/en/

Save it to your PC then close all browsers and install it. Note on Java and Firefox. For some reason Java does not remove old consoles from Firefox. Any time you update Java you should do Firefox, Add-ons, Extensions and disable any old Java Consoles

They will look like: Java Console 6.xx. The xx corresponds to the update number. When they switch to 7 update 0 then it will be Java Console 7.

Multiple Java Consoles will slow down the Firefox boot. After any change to Firefox or its extension you should run Speedyfox. (Mentioned later.)



Also make sure you have the latest versions of any adobe.com products you use like Shockwave, Flash or Acrobat.

Whether you use adobe reader, acrobat or fox-it to read pdf files you need to disable Javascript in the program. There is an exploit out there now that can use it to get on your PC. For Adobe Reader: Start, All Programs, Adobe Reader, Edit, Preferences, Click on Javascript in the left column and uncheck Enable Acrobat Javascript. OK Close program. It's the same for Foxit reader except you uncheck Enable Javascript Actions.

To help keep your programs up-to-date you should download and run the UpdateChecker:
http://www.filehippo.../updatechecker/
(You don't need to download Betas and if there is a program you don't use you can just uninstall it rather than update it. You can right click on the updatechecker icon (looks like a downward green arrowhead) and select Settings and tell it no betas. If you don't use MSN Messenger I would not upgdate it. MS installs a bunch of stuff when you do. You can tell the program to not show you that update.)
If you use Firefox or Chome then get the AdBlock Plus Add-on. WOT (Web of Trust) is another you might want to try.
The equivalent to AdBlock Plus for IE is called Simple Adblock and you should install it too: Adhttp://simple-adblock.com/

If Firefox is slow loading make sure it only has the current Java add-on. Then download and run Speedy Fox.
http://www.crystalidea.com/speedyfox . Click on Speedup my Firefox. When it finishes click on Exit.

Be warned: If you use Limewire, utorrent or any of the other P2P programs you will almost certain be coming back to the Malware Removal forum. If you must use P2P then submit any files you get to http://virustotal.com before you open them.

If you have a router, log on to it today and change the default password! If using a Wireless router you really should be using encryption on the link. Use the strongest (newest) encryption method that your router and PC wireless adapter support especially if you own a business. See http://www.king5.com...-120637284.html and http://www.seattlepi...ted-1344185.php for why encryption is important. If you don't know how, visit the router maker's website. They all have detailed step by step instructions or a wizard you can download.

Thank you so much Ron :happy: I am so relieved.

I have copied your advise and will do whatever you have advised, tomorrow after I send my work.

I don't use Limewire. I will update Java with the latest.

Will come back tomorrow and give my feedback.

Thank you so much.... :)

Have a great day.

Try

"f:\my documents\Downloads\ComboFix.exe" /uninstall

The space between my and documents is causing the problem.

You can also leave Combofix if you want to or manually delete the program on your desktop as well as the C:\qoobox and C:\Combofix... folders.

I just gave "Combofix /uninstall" and ran it. It has been uninstalled.

I have downloaded the latest Java...... and will do all the checks that you advised me to do. I am so relieved.

If I have any computer problems in future "Geeks to go" is the first place I will visit.

Thanks a ton Ron :)
