Hi batlon13,
Seeing this has happened suddenly, please read the following article to check for possible malware.
How to Know If Your Computer Is Infected

Could you tell us a bit more about your system? What hardware, OS and security program(s) are you using? Which security programs run in the background and which ones do you use on demand only?

Please make sure that there are no left overs of previously uninstalled security programs around. Not all uninstallers do a proper job. And left over applications, drivers or services can cause all sort of “interesting effects”.

Try using removal tools for those programs to remove them. Here is a list of removal tools for common av programs: ESET Knowledgebase .

Also it is a good idea to ensure your drivers and software are all up to date as this can affect performance also.
