The last updates I installed were on 6/17 and they were kb978695, 975562, 979482. I didn't get an error until today so I don't know if this is related. All of a sudden I am getting Runtime error! Program: CProgram files\Internet Explorer\iexplore.exe, R6025 - pure virtual function call. Once you click ok the browser closes. It happened at a couple of bank sites. I've googled for a fix and saw lots of people have had this problem but I didn't find a solution. The only other thing I changed recently was that I replaced a CD-RW drive yesterday. But I did not install any drivers. IE 7 WinXP SP3 Will system restore help? Thanks for any advise.
