Windows 7: Strange behaviour started happening with my HP desktop

Recently when I put my pc into sleep mode a lot of the time it wont let me wake it up and i have to power down and restart and then it takes ages to set itserlf up and wont let me get any network until i restart the computer from the start menu, I have ran SUperANtiSpyware scan and it found nothing and i also ran an AVG virus scan which found nothing..And also the other day when i had to do this CHKDSK done all sorts of stuff before it would start....I would be grateful if you can help me with this problem.,

I am using a HP Pavillion a6455 with 3gb ram and large HDD and also an ATI card.

Thanks

Run another full scan with Malwarebytes to make sure all malware was removed.

Wouldnt the first one catch everything then ??
I've noticed that the behaviour is still happening.

In a perfect world, Malwarebytes would catch the malware and remove it all in the first shot. However, antivirus software and antimalware software often needs to be run a second time to make sure everything that was caught is actually removed. Some viruses and malware are designed to be difficult to remove, so there are no guarantees the software that finds it also removes it the first time (or even on subsequent times). Occasionally, malware and viruses require an offline (outside Windows) scanner to remove them.

Ok,,,i have done another scan,,,ir returned four results of CrossRiderApp and after looking into this i realise that it isnt harmful and it is used to make chrome extension...If you think I should delete it then let me know..But if not then there is definstaely another problem somewhere else in my pc and it would be great to get it fixed...

You will want to remove the app. It does not look like a good app to have on your system. How to Uninstall/Completely Remove Google+Facebook App From your Computer
