mikea,

Hi and welcome to the Daniweb forums .

-

Download, then unzip to "C:\HJT", the newest version of HiJackThis; version 1.99.1. Then repost your log, either now, or after following the steps in the solution (if provided in this post). This version has features that might be more helpful in 'cleaning' up your system.

===============

Next, we need to remove(uninstall) the 'lop' infection by going to here, then downloading and running the uninstaller(s) that relate to the application(s) your wanting to remove. The following selections are available: "Start page", "Search engine", "Accessories Toolbar".

After uninstalling any (or all) of the above, let's see if we have anything in "Scheduled Tasks":

Download, unzip and run ScheduledTasks.bat (courtesy of ddeerrff), and when notepad comes up, post the contents back to this thread.

===============

Still in HiJackThis, click "Scan", then check(tick) the following, if present:


R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Bar = http://www.yssvefldorobqqerbcgcnkj....QMW7rgwbIrA.php
R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Local Page =
R0 - HKLM\Software\Microsoft\Internet Explorer\Main,Local Page =

O4 - HKCU\..\Run: [htmmedia] C:\DOCUME~1\MeikaA\APPLIC~1\FIVEME~1\warn memo ball.exe


Now, with all windows closed except HiJackThis, click "Fix checked".

===============

Locate and delete the following item(s), if present. Make sure your able to "view system and hidden files/ folders:"

folder...

C:\DOCUME~1\MeikaA\APPLIC~1\FIVEME~1

-

Note that some of these file(s)/folder(s) may or may not be present. If present, and cannot be deleted because they're 'in use', try deleting them in "Safe Mode".

-

Reboot.

===============

After rebooting your PC, rescan with hijackthis and post a new log.
Let me know how things are now.

Back again thanks for the help Hijackthis log follows, didn't trust the uninstaller,my antivirus saw it as a virus so I ran away. The scheduledtasks.bat didn't seem to work (page unavailable) Did everything else, what does the log look like now?

You really should run the uninstaller. It is a legitimate uninstaller that is recommended on many sites and which I advise to use for this infection with zero problems noted to date .
As you can see, you are still infected with LOP. Your AV just picked up the word LOP somewhere and alerted you (falsely).

Scan with hijackthis and tick the boxes next to all the following entries, then close all browser and explorer windows and hit the "Fix checked" button.
