Possible malware connected to Bing searches - Microsoft Community

i've had repeated malware turn on pc, each time quarantined defender until removal.  file roguetechjsa (or ending in e or f).  turns again until offline scan run which finds infected file keeps letting in malware.  defender identifies trojan horse type.

what has caused me wonder if somehow connected bing, strong coincidence -- each time it's happened has been after bing search.  don't search internet on regular basis, had on several occasions searching rolls of discontinued wallpaper.  brought bing mind not had used search, after last malware attack, had gone week free of having malware turn -- until ran bing search trying find info on over counter anti inflammatory cats.  , malware turned again.  removed again , did offline scan found infected file.  2 days , no bing searches later, no malware attack far.

is possible malware this?  know phish attacks can hooked search engines, either redirection when going to a web page search result, or somehow hooking search keywords.  once tried go page on search results pond fish food , instead had official looking 'fbi' web page appear telling me 'for security reasons computer has been locked , files encrypted' , click yes go fbi page prove identity , unlock pc.  clicking no brought 'are sure?' dialog couldn't cancelled.  had use task manager shut down this preposterous scam.  other phish resulted, ironically, when keyword security accidentally searched (clicked on drop down list accident).  instead of search results, got official looking dialog box windows had detected a virus penetration of firewall (there techie sounding file name) , had locked computer , must call number on screen ms access computer , clear virus.  'honest' enough there'd small fee -- might not have been small either way they'd have credit card number , access pc later.  wasn't initiated by microsoft.  i used task manager shut down too.
