two problems: YAC infestation and WSPlayer takeover!!

Florio · 07 May 2014

I really hope someone can help me, as I'm in hot water up to my neck!

My computer has just had a YAC infection; I did a quick scan with Malwarebytes which picked up 5 threats. I removed these, but there are still elements on my desktop (like a memory and speed gauge) which I cannot get rid of. YAC no longer appears in my list of installed programs (Control Panel) so I don't know what to do.

The other problem regards my videos. I have a large number of .avi files stored on my laptop which I've always played with Media Player Classic. Now these will not open; I see that the files have been renamed WSPlayer.avi even though I have no WSPlayer on my PC. I went to Default Programs (or whatever it's called in English -- I have an Italian version of Windows 7) to change the program to use when playing .avi files, only to find that .avi files are no longer included in the list. Neither are mp4 or mkv files, all of which I normally play with Media Player Classic.

I'm tearing my hair out here, so I'd really appreciate some help if you know what to do!

Have you run system restore to a point before you were infected?

Please download AdwCleaner by Xplode and save to your Desktop.
Step 1.

Double click on AdwCleaner.exe to run the tool.
Vista/Windows 7/8 users right-click and select Run As Administrator.
Click on the Scan button.
AdwCleaner will begin...be patient as the scan may take some time to complete.
After the scan has finished, click on the Report button...a logfile (AdwCleaner[R#].txt) will open in Notepad for review (where the largest value of # represents the most recent report).
The contents of the log file may be confusing. Unless you see a program name that you know should not be removed, don't worry about it. If you see an entry you want to keep, let me know about it.
Copy and paste the contents of that logfile in your next reply.
A copy of all logfiles are saved in the C:\AdwCleaner folder which was created when running the tool.

Step 2.
Using AdwCleaner v3: Scan & Clean:
This time click on the Clean button.
Press OK when asked to close all programs and follow the onscreen prompts.
Press OK again to allow AdwCleaner to restart the computer and complete the removal process.
After rebooting, a logfile report (AdwCleaner[S#].txt) will open automatically (where the largest value of # represents the most recent report).
Copy and paste the contents of that logfile in your next reply.
A copy of that logfile will also be saved in the C:\AdwCleaner folder

Post both .txt logs in your next reply.
