Malicious cookies

Thanks for replying Le Boule.

The antivirus protection I have is McAfee.  I also use a free Malwarebytes scanner.  When I ran into the Trojan virus, a message directed me to call Microsoft where they did a scan and informed me that I had tracking cookies on my computer from the virus.  I also ran a free scan from Scanguard which showed the cookies present also.  However Scanguard turned out to not be reputable and I had to delete it along with info that it put on my computer.

I also use JRT but they did not find anything.  I have a lot of reading to do with the information you sent to me...thank you so much.  If there is anything else you can help me with, I need all of the help I can get.  Lol.  I'm a layperson when it comes to the tech side of computers.

Thanks again for your help!  I really appreciate it!

I’m sorry but I don’t understand your post about tracking cookies being put on your computer by a virus.  https://www.symantec.com/security_response/writeup.jsp?docid=2006-080217-3524-99&tabid=2

What advice/assistance did you receive from McAfee?

The popup you saw directing you to call MS was part of a tech support scam…you should have been able to shut down the browser popup using Task Manager (if necessary).  Note that MS does not call you or send you a popup on your computer telling you you have a virus and to call a certain number for tech support.

See the following:

And you have run scans with McAfee and Malwarebytes and neither has identified any malware?

Are your docs/pics/music/etc backed up?

Since you allowed the scammers access to your computer be sure you change passwords and consider all personal and financial data in the computer to be potentially compromised...you may need to confer with banks, credit card providers, etc. and possibly change your account numbers - recommend you seek their advice on what to do.

And

Since you allowed the scammers to access your computer some IT Professionals suggest you confer with a professional computer repair tech and/or consider a reset (or clean install) on your computer.  That decision of course is up to you.

Good luck…

Can anyone tell me how I can manually delete malicious cookies from my computer? I am using Windows 10 with Google Chrome and Edge.  Malwarebytes did not detect anything but I ran a few other scans that showed I had 3rd party malicious cookies stored on my computer after I had a run-in with a trojan.  Thank you.

You posted in the Microsoft Security Essentials Forum.  That’s a MS antivirus program that may be installed if you want to use it on Win 7 – it will not work on Win 10.

What antivirus program are you using on Windows 10?

What scanner(s) indicated the presence of cookies?  MS products don’t identify and remove cookies since cookies themselves are not considered malicious.

We generally recommend the scanners listed in List of Malware Removal Tools though adware scanners such as Adwcleaner and Superantispyware are also reputable programs.
