Start Up Problems

I'm new to this and i recently got a problem i just could not solve. it drives me crazy . When i start up my wifi icon in my try says there is a connection problem and i'm connected through wire and when i click on it, the area where it shows the available connections won't open however i am able to right click it and i can't open network and sharing center. my hidden icons are also messed up, my Microsoft Security Essentials is saying it's at risk but i am unable to right click on that and open it until sometime later for some reason it magically works again and it is not actually at risk. Final thing there are only 3 hidden icons when there should be 6, the 3 are Microsoft Security Essentials, Intel(R) HD Graphics, and Intel (R) Rapid Storage Technology. Everything loads up and works again sometime after i start up except the wifi icon i needed to reconnect to my network to correct the icon.

Programs i have for viruses, etc
Microsoft Security Essentials
Spybot S&D
Malware Bytes
Glary Utilities
CCleaner
I had AVG but i uninstalled it for MSE

I would greatly appreciate if you helped me since i am very paranoid with my laptop's safety

Yes, i scanned with malwarebytes(quick), mse(quick), and spybot but there was nothing except the facebook.messenger which i think is a false positive from spybot

I scanned using cmd but it says it didn't fix anything

Please help it takes forever to load up and during that time i am unable to open almost everything except chrome, mozilla, etc but i cant open network and sharing center. I will try all suggestions

also i have noticed that everything starts to load up again as intel task tray framework icon appears in the taskbar however this icon disappears when everything becomes fine.

I have also noticed in my task manager csrss.exe has no information at all except how much memory it is using. Working set memory 18k, memory private working set 2k. winlogon.exe, sddt.exe also has no information

Did you use the Removal Tool to completely get out the AVG crapware? Uninstallers (removal tools) for common antivirus software - ESET Knowledgebase

Spybot is also not favored here. Use SUPERAntiSpyware.com - Downloads

Check if System Files have been damaged, establish a Clean Boot and the other Troubleshooting Steps for Windows 7 to go over your install completely.

But if this is the original Dell factory Preinstalled WIn7 it is larded with bloatware and duplicate utilties which interfere with better versions built into Win7. So I'd do like most tech enthusiasts and Clean Reinstall - Factory OEM Windows 7
