A customer has an issue with his Dell laptop whereby he can add the network printer and all seems to work, but it doesn't talk. IP address is set up correctly and the driver is the latest one of the correct type. Uninstalling and reinstalling produces no results.
I also noticed at the time that certain programs wouldn't open - you could see the cursor flicker and change for a split second after double-clicking on the shortcut/ executable, but then... nothing. From memory, the process didn't even show in task manager (or I blinked for the moment it did, though I doubt this as it was tried many, many times). In some cases, the process showed up in the process tab, but nothing in the application tab. Waiting for many, many minutes produced no further result.
For whatever reason, I tried to remove Norton 360. It didn't want to via 'Programs & Features', so I tried the Norton removal tool (not the latest one- perhaps I should download that and try again) but was told by that program that I needed to uninstall via 'Programs and Features'.
I ran MBAM, ESET Smart Security, SuperAntiSpyware and a few others and only found some very minor stuff - no worms or Trojans to speak of.
Please suggest the next best course of action. I don't want to have to back-up/ format/ reinstall windows/ restore data, but I'm at a loss as to a better (and quicker) option.
I look forward to your solution!
