  To do: Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly.

  Method 2:

  Launch the virus in safe mode with network scan.

  Step 1:

  Start your computer in safe mode with network.

  http://Windows.Microsoft.com/en-us/Windows7/start-your-computer-in-safe-mode

  NOTE: see 3 from the link above, Advanced options boot (including safe mode).

  http://Windows.Microsoft.com/en-us/Windows7/advanced-startup-options-including-safe-mode

  Select Mode safe mode with networking.

  Step 2:

  I suggest you run an antivirus scan using the Microsoft Safety Scanner to confirm that your computer is free from any infection by the virus. Please find the link below.

  http://www.Microsoft.com/security/scanner/en-us/default.aspx

  Note: The data files that are infected must be cleaned only by removing the file completely, which means that there is a risk of data loss.

  Note: The Microsoft Safety Scanner ends 10 days after being downloaded. To restart a scan with the latest definitions of anti-malware, download and run the Microsoft Safety Scanner again.

  The Microsoft Safety Scanner is not a replacement for the use of antivirus software that offers continuous protection.

  Hope the information is useful.

• Screen flickers black when you use Photoshop CC 2015

  I am under Photoshop CC 2015 with a 13 inch, Macbook Pro late 2013 OSX 10.10.3

  My screen flashes black when I use the program (really bad with the text tool)

  How can I avoid this / solve the problem?

  • This occurs generally when there is a problem with the graphics card.
  • Open Photoshop > preferences > Performance > avancΘs
  • Set the mode for drawing base.

  

  • Restart Photoshop and see if that helps.

  Hello Sarika

  Thanks for your help.

  It's not that simple I thought he'd be when I used your method that whenever I tried to uncheck 'Use graphics processor' Lightroom 6 crashed.

  At least you put me on the right track and I persevered and found the file relevant agprefs of Lightroom web help and followed the instructions to change manually.

  I have changed two files with the same name but stored in different locations.

  Everything works fine now.

  Thank you once again.

• Once the standard screen saver is used, all Firefox Windows go totally black with the exception of the title bar, only closing and restarting solves FF.

  Windows XP SP3. It started with Firefox v.18.0. When an activity cancels the screen saver, display back, except Firefox. FF window will be closed using the 'X' angle, but no other toolbars are visible or functional. No new modules since the 18.0 update.

  Try disabling hardware acceleration in Firefox.

  • Tools > Options > advanced > General > Browsing: "use hardware acceleration when available.

• Start FireFox, download flash of white boxes and then sceen becomes black. Said above "Search - Mozilla Firefox" no just all black of the taskbar.

  Trying to help a friend. Their return from holiday. When she tried to start FireFox, the only thing it shows is a black screen. I updated the version and tried. Same result. FireFox ininstalled 'workstation. Downloaded FireFox and installed. Once again, same result. FireFox starts, but after a very second cherry where it show 2 empty boxes and then the screen goes black. The only thing is the search - Mozilla Firefox at the top left. There is nothing else to see or open.

  Try to start Firefox in Mode safe mode by holding down the SHIFT key by double-clicking on the icon.

  If it helps, try disabling graphics hardware acceleration where there is an incompatibility of the graphics driver.

  You need to restart Firefox for it to take effect, so save any work first (e.g. you compose mail, documents online that you are editing, etc.).

  the button Firefox orange (or the Tools menu) > Options > advanced

  In the mini ' General' tab, uncheck the box for "use hardware acceleration when available.

  If you restart Firefox, is the problem solved (or at least enhanced)?
