I was helped for a seriously infected computer less than a month ago. I have a dimension 2400 running win xp home edition. After my computer was put back in working order at the end of February I was unable to post or attach files.This problem was resolved when I installed an automatic update which (I believe) updated my browser from ie6 to ie7. Everything was working fine until I encountered a problem with my printer. I uninstalled the printer(HP 1310 PCS) through windows add/remove utility. When I tried to reinstall the program froze and my computer issued a blue screen. I could only log on in safe mode. I tried System Restore but it could not restore to any previous date. To resolve the problem I installed the back up I had created with ERUNT. It was then that I discovered that ie7 becomes inoperable when you install any back up or run system restore. So I uninstalled ie7 and I am back using ie6 complete with the problem of not being able to post or attach files. Sorry for the lengthy post. I also have defender pro as my anti virus protection and firewall.
I have internet explorer 6 and sbc yahoo browser, I get the same error message in each one - internet explorer has encountered a problem and needs to close - this happens whenever I try to attach a file or post a response in my online classes.
