Desk top short cuts not working

I pressed Ctrl Alt Delete and the CPU was 100% I found what it was and ended it. The last time this happened I had some major viruses. Still no history being recorded either and this happened last time as well. I run Avast and have Windows Defender.

Please help.

 

Hi and welcome.

If you could, can you recall what process it was that was hogging up all your CPUs?

Then please do as instructed below.

Here is how we like to begin our analysis of your pc:

For starters, if you do not have them yet, please DL and run AdAware & Spybot Search & Destroy.AdAware and Spybot Search & Destroy are 2 of the most trusted apps in the security area. They are both free, compliment each other nicely, and do not use a lot of resources. They can be found here:

Spybot Search & Destroy v.1.4
AdAware SE Free v1.06r

With AdAware and Spybot: DL, follow the install instructions, check for updates, then scan, repair/remove/quarantine anything found. Reboot before next scan with whichever app is next. The reason for running these apps, is to clean up some of the other 'crapware' on your pc, which, in turn, will make deciphering your HJT log, easier.

Then we use HiJackThis v:1.99.1zip.
DL the zip file to your desktop, then create a new folder on your C drive, called 'HJT' or 'HijackThis'. Then unzip the files to the new folder. When you run HijackThis.exe from C:\HJT folder and have it "Fixed checked" it will create a backup file of modifications to use if restore is necessary which is easily accessible.

Run the program, and press Scan. You will notice the Scan button will turn into a "Save Log" button. Save the log and Post that log onto this topic. DO NOT DELETE or modify anything yet, as some of it is needed to keep your system in proper working order.
