My friend is getting both a Microsoft C++ Runtime Error and the R6025-Pure virtual Function call with the Yahoo Messenger. She has uninstalled and reinstalled Messenger a number of times. What could be causing this problem?
There is a huge difference between running a scan in normal mode, and safe mode with networking.
I'm not sure what her regular security program is, but malwarebytes is a higher quality scanner than OneCare. SuperAntiSpyware is also another good scanner.
But because there are a lot less services and programs running in safe mode, there is a lot less chance any infection will be running. You want to boot into safe mode with networking, because you always want to update the scanner's database before running the scan.
