Question
QUESTION: My nephews laptop keeps showing a pop-up saying Warning! Virus detected.  (Trojan-PSW.Win32.Antigen.a)  When this pops up it also "screams".  This laptop does not have any virus protection on it at this time.  I was looking for  free anti-virus software but thought we should remove the virus first.  I would appreciate any help you can give.

Thanks

Pam

ANSWER: Hi Pam

Yes, you will need to get rid of the infection before installing any real-time AV protection.  Restart the computer in Safe Mode by continuously tapping the F8 key on boot until a black screen with a menu appears.  Choose to Start Windows in Safe Mode with Networking.  Log on as usual.  

Download Malwarebytes' Anti-Malware to your desktop from here:

http://www.besttechie.net/tools/mbam-setup.exe

Double-click mbam-setup.exe and follow the prompts to install the program.
* At the end, be sure to update Malwarebytes' Anti-Malware and run a Full Scan.
* When the scan is complete, click Show Results to view the results.
* Be sure that everything is checked, and click Remove Selected.
* When completed, a log will open in Notepad.  Save that log and reboot normally.

Download and install HijackThis:

http://www.trendsecure.com/portal/en-US/_download/HJTInstall.exe

Make sure you close EVERY open window and ALL browser windows. The only thing that should be open is the HijackThis program.
Double-click on the file you just downloaded.
Click on the "Install" button.
Upon install, HijackThis should open for you.
Should it not open, go to C:\Program Files\Trend Micro\HijackThis and double click on HijackThis.exe
Choose 'Do a system scan and save a log file'.
Copy the text file which opens in Notepad and paste it in a follow-up to me, along with the Malwarebytes log.
* Do not fix any entries in HijackThis, as they may be harmless.

QUESTION: Here is the HJT log.  The Malwarebytes log is too long for me to send, it wants me to shorten it.  Thanks for your help.

Hi Pam

Please run HJT and place a check mark in the box next to the following entry, close any open browser windows, then click the Fix Checked button:

O2 - BHO: (no name) - {5C255C8A-E604-49b4-9D64-90988571CECB} - (no file)

Other than that, everything else looks good.  As long as the pop-ups have stopped, I'd say you can go ahead and install Avira.  Have the program run a full scan after you install it.  If there are any other problems, just let me know.
