I have a client that I'm trying to help out via remote login. They tried installed a game off the Internet on Monday night and every since then they cannot open any programs off their desktop like Quickbooks, Word, Excel etc. I can use Firefox to browse the Internet just fine and download any program.
So I have ran full scan with avg in normal mode and safe mode with no infections found. I've also ran Rkill and Combo Fix which didn't help anything. I've also disabled all start up items via msconfig (after getting access to it).
When I go to install Malwarebytes, I get errors towards the end on the .lnk files that it won't work all the way through. The error is CoCreateInstance failed; code 0x80040154. Class not registered.
If i manually browse to program files > malwarebytes I can see the .exe to run but get a run-time error '372' failed to load control 'webbrowser' from ieframe.dll. your version if ieframe.dll may be outdated. make sure you are using the version of the control that was provided with your application.
Computer is older with Windows XP SP3
Any ideas?
1) Like the person above said... Do a system restore.
2) Right as the computer boots up open Task Manager (Ctrl-Alt-Del) as quickly as possible and end any task that should not be running (requires you to know what are standard system tasks). A lot of viruses will start when your computer does but there is normally a few seconds of lag before they do and you can sneak in some commands before that. If you have a second computer available check the running tasks on the internet. More times then not the major antivirus makers will post instructions on how to manually remove a virus from your system if you can locate which one it is.
My advice would be to forgo trying to recover the system though and just restage it.
