Without singling out anyone in particular, I post the following:

Part of the issues appears to be the lack of software updates to some personal computers. I'm not talking about just a browser update, but a lack of system software updates. Also, updates to java have to do with some of the issues being experienced.

I suggest those having issues first clean out their system and browser cache, the simplest way to do so on a Windows based system would be to hit your start button, then click "all programs", then click "accessories"and click on the folder "system tools". Next click "disk clean" , choose all hard drives (make sure they are checked off),then make sure that all boxes are checked off when the system shows things to be deleted.

System software wise:

Microsoft update has their own site which will show any and all Microsoft updates for your systems (some of you will need to run this more than once)
Microsoft Update

The latest Java can be found here:

Download Free Java Software

Finally, some of you can have malicious software (regardless of what your anti virus software co states) on your local system(s). I highly suggest the following two pieces of software to clean your system (both have free versions). This would be on top of whatever your favorite anti virus software is (provided you update it frequently)

Malewarebytes
Malwarebytes

Spybot search and destroy
The home of Spybot-S&D!

Again,updates to your system and browser can eliminate 75% of the issues at hand. The other 25% Brent is working on as fast as he can.

As always,hope you find this helpful.
