I bought a new PC recently running Vista and after a week or so I began to get the Buffer Overrun C++ message - Program: C:\Program Files\Yahoo!\browser\ybrowser.exe when I click on BT Yahoo! Broadband. I discovered I had a trojan virus which I got rid of using Superantispyware.
I can access the Internet via BT Yahoo! Online but the above message comes up intermittently. The HJT log is shown below andI would appreciate help in tackling this. Is it simply a matter of reloading ybrowser.exe? If so how could I do that?
