Safari is crashing and hanging ALL the time.... Help PLEASE??

OK...

I have been having this issue with Safari hanging and crashing all the time.....

I am at a loss as to what to do about it.....

I have backed my computer up with TimeMachine...

I want to get rid of these straggling items from these Apps so that if I do

a clean install from TimeMachine, I don't end up with these remaining items left from these Apps.....

now there were a few apps I had downloaded to see if they could help me

find possible corrupt files....

Now, I am unable to get these Apps out of my computer,.....

I have located these various items and folders and shown the path on how I got to these

items and folders......

Is it safe for me to trash these folders of uninstalled Apps????

Folders I want to trash….

finder > time machine line…. In my TimeMachine back up disk....

Folder Backups.backupdb

Folder My MacBook Pro

Folder 2014-2-14 Date & time of back up

Folder Macintosh HD

Folder Library -

***Folder Application Support -- **** has Folder named Symantec*** I UNinstalled this last week…

Can I safely drag this folder to the trash????

Now secondly…..

Go back to Library…..

Folder Preferences -- Has a bunch of Sophos items…

com.sophos.ac.plist

com.sophos.ac.plist.lockfile

com.sophos.dc.plist

com.sophos.dc.plist.lockfile

com.sophos.sau.plist

com.sophos.sau.plist.lockfile

com.sophos.sav.plist

com.sophos.sav.plist.lockfile

Can I safely drag these items to the trash????

if not, How can I get these out of my computer???

In finder window when I eject a HDD….

UNder Macintosh HD

Users> Shared>

Folders of Applications I have uninstalled….

CleanMyMac 2 - Folder

MacPaw Gemini- Folder

Can I safely drag these to the trash ???

If not, How can I get rid of them completely?????

also in my SHARED Folder …..

There is also an item called NavAPvc.log

what is this item ????? and does it belong there????

I am FULLY aware that it was stupid of me to load these on my MacBook ....

and this is why I have uninstalled them......

I have been having issues with my MacBook for a LONG time now.....

I think I might have some corrupt files on my computer and would like to locate them and try

to remove them if somebody can please help me.....

Now, I have tried resetting Safari.... This did not help.....

I also disabled Extentions..... This also did not help....

I only have 2 extentions..... Google Translate and Ad Block....

and like I said,... disabling them doesn't help at all......

Thank you in advance for your help with this......
