Everytime I try to save something my browser freezes?

[Xavier]

It happens with IE, FF and Chrome. It's only just started happening tonight. Whenever I try to save something (no matter what it is from any website) the Explorer "Save As" dialog appears blanked out and then it just freezes forcing me to do an end task.

I've tried running CCleaner and rebooting but it still happens.

(Win 7 Pro)

Just Restore the system to a previous day, by Going to Start, all programs, Accessories, System Tools and then System restore. Click on it and select a previous day, on available restore points, when you did not have the problem. It is simple and secure. Your files and downloads will be intact. It will only remove the system files addition, which is responsible for your problems.
If it does not solve, then download malwarebytes from malwarebytes.com and scan ur computer and delete them by selecting all in the SHOw result box after the scan
The first solution is the best in these kind of unknown problems
