Solvusoft malware?

[MDV]

I think I'm infected.

After reinstalling skype, a pop-up alerted me about RAVBg64.exe.
Looking for it I found this page:
 

https://www.solvusoft.com/it/files/errore-rimozione-virus/exe/windows/realtek-semiconductor-corp/hd-audio-background-process/ravbg64-exe/

and downloaded a file clicking the download button. After running the file a pop-up alerted me of something wrong  (memory limit exceeded?...) and the file desappeared from the download directory.

Please, help me. Thanks

Hello MDV and welcome to Malwarebytes,

The link you posted checks out as clean at VirusTotal:

https://www.virustotal.com/en/url/c958e48f8021bae353a01361b50fb0f26ef5c820282a3b624a96d616ef37e0f6/analysis/1510055889/

ravbg64.exe is part of Realtek HD audio background process. It is related with Realtek audio programs. The file name in the link you used differs slightly rav64-exe Note the hyphen between the name and exe.... Not sure if that makes any difference, but lets investigate further...

Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into. "Do not open that file"
NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

Open FRST and press the Fix button just once and wait.
The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply.

Next,

I want you to run Malwarebytes again, this time I want "Rootkits" enabled, please use as follows:

Please open Malwarebytes Anti-Malware.   On the Settings tab > Protection Scroll to and make sure the following are selected: Scan for Rootkits Scan within Archives   Scroll further to Potential Threat Protection make sure the following are set as follows: Potentially Unwanted Programs (PUP`s) set as :- Always detect PUP`s (recommended) Potentially Unwanted Modifications (PUM`s) set as :- Alwaysdetect PUM`s (recommended)   Click on the Scan make sure Threat Scan is selected, A Threat Scan will begin. When the scan is complete if anything is found make sure that the first checkbox at the top is checked (that will automatically check all detected items), then click on the Quarantine Selected Tab If asked to restart your computer to complete the removal, please do so When complete click on Export Summary after deletion (bottom-left corner) and select Copy to Clipboard.

You`re very welcome, run the following to cleanup/remove tools used:

Download "Delfix by Xplode" and save it to your desktop. Or use the following if first link is down: "Delfix link mirror" If your security program alerts to Delfix either, accept the alert or turn your security off. Double Click to start the program. If you are using Vista or higher, please right-click and choose run as administrator Make Sure the following item is the only one checked:   Remove disinfection tools <----- this will remove tools we have used. Now click on "Run" and wait patiently until the tool has completed. The tool will create a log when it has completed. We don't need you to post this. Any remnant files/logs from tools we have used can be deleted… Next, Read the following links to fully understand PC Security and Best Practices, you may find them useful.... Answers to Common Security Questions and best Practices Do I need a Registry Cleaner? Take care and surf safe Kevin...
