Invisible window content

[g1o2r3a4z5d6]

I'm having trouble with the display of some applications. I have added two attachments. First was supposed to be weather gadget but it's invisible, although all the buttons are still present (see attachment 1). The other problem are any third-party programs for example Adobe Reader installer would be just black screen, however, still working. Because I knew the buttons 'install' and 'done' are in the right down corner I was able to install it normally, however, no window content was seen. The second attachment should be AVG notification about update, but as you can see, it's black as well.

It started appearing today, after installing several programs using UVK (Ultra Virus Killer) and Tweaking.com Windows Repair.

I have no malware, scanned several times with MBAM, Hitman Pro, AVG, SAS, TDSSKiller and more.

How should I address the issue?

Thanks anyone for the answers.

I would use System Restore and choose a restore point before you installed the programs and see if the problem goes away. Then I would install the programs one by one and see when the problem comes back.

It could also be the tweaking that you did with Tweaking.com, you may not be able to undo that if no restore point was made before you used it.

My 2 cents worth go with Mellon Head and mate get rid of the trashy software. You don't need much more than these for tweaking and they are safe

For one more option you could try one of these the Kaspersky one is quite good.
