does anyone know how to uninstall "Topic Torch by WebCake"?

Check Safari/Preferences/Extensions see if it is there, if so delete it.

If not there check here.

From finder window click Go in them menu bar>Computer>your HD>Library>internet plugins, if you find it there highlight it and command delete (Also any associated files)

Your desktop, it will say Finder in the upper left of the menu bar

MMM, I am not familiar with this, and their website is not much help.

Is there a logo in the menu bar? (The top bar that's always there) if so try clicking on it and selecting unistall, or try control clicking on it and see if uninstall is in the menu.

Also, just a shot in the dark, try going to system preferences/users groups, and click on login items, see if it there, if so highlight it and clcik the minus symbol.

Please read this whole message before doing anything.

Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. Step 1 should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.

Triple-click anywhere in the line of text below on this page to select it:

{ echo "Loaded kernel extensions:"; kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}'; echo $'\n'"Loaded user agents:"; launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)|\.[0-9]+$/{print $3}'; echo $'\n'"Inserted libraries:"; launchctl getenv DYLD_INSERT_LIBRARIES; echo $'\n'"User cron tasks:"; crontab -l; echo $'\n'"System launchd configuration:"; cat /e*/lau*; echo $'\n'"User launchd configuration:"; cat .lau*; echo $'\n'"Login items:"; osascript -e 'tell application "System Events" to get name of login items' | sed $'s/, /\\\n/g'; echo $'\n'"Safari extensions:"; /usr/libexec/PlistBuddy -c Print L*/Saf*/*/E*.plist | awk -F'= ' '/Bundl/{print $2}' | sed 's/\..*$//;s/-[1-9]$//'; printf "\nRestricted user files: %s\n" $(find ~ $TMPDIR.. \( -flags +sappnd,schg,uappnd,uchg -o ! -user $UID -o ! -perm -600 \) | wc -l); echo $'\n'"Extrinsic loadable bundles:"; cd; find -L /S*/L*/E* {,/}L*/{Ad,Compon,Ex,In,Keyb,Mail/Bu,P*P,Qu,Scripti,Servi,Spo}* -type d -name Contents -prune | while read d; do /usr/libexec/PlistBuddy -c 'Print :CFBundleIdentifier' "$d/Info.plist" | egrep -qv "^com\.apple\.[^x]|Accusys|ArcMSR|ATTO|HDPro|HighPoint|driver\.stex|hp-fax|JMicron|print|SoftRAID" && echo ${d%/Contents}; done; echo $'\n'"Unsigned shared libraries:"; find /u*/{,*/}lib -type f -exec sh -c 'file -b $1 | grep -qw shared && ! codesign -v $1' {} {} \; -print; echo; ls -A {,/}L*/{La,Priv,Sta}* L*/Fonts; } 2> /dev/null | open -ef

Remember that you must be logged in as an administrator for this step. Do as in Step 1 with this line:

{ echo "Loaded system agents:"; sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; echo $'\n'"Login hook:"; sudo defaults read com.apple.loginwindow LoginHook; echo $'\n'"Root cron tasks:"; sudo crontab -l; echo $'\n'"Log check:"; syslog -k Sender kernel -k Message CReq 'GPU |hfs: Ru|I/O e|find tok|n Cause: -|NVDA\(|pagin|timed? ?o' | tail | awk '/:/{$4=""; print}'; } 2> /dev/null | open -ef

You can then quit Terminal.

Note: If you don’t have a login password, set one before taking Step 2. If that’s not possible, skip the step.

Remember, Steps 1 and 2 are all copy-and-paste — no typing, except your password. Also remember to post the output as text, not as a screenshot.

What extensions are shown in Safari - Preferences - Extensions ? (Yontoo, maybe ?).

Try switching them all off.
