indeed, only Umbra Total Security can gives you 100% prevention/removal rate ! check the awesome rewards my product received !!!!
and removing capabilities of Classic AVs doesn't guarantee you that your system is really cured; you have to use complex forensic tools that will take hours to check all potential infected areas. I rather format and install/restore a clean system.
Im not considering myself ! i am one, im The One !
Indeed curing manually a system will be too long , not saying i won' t let anyone do whatever they want on my system ! and surely not a support guy which have no clues on how my system is set.
Just look in various forums , at all those amateurs using Malwarebytes Anti-Malware, Combofix , or whatever tools .... after lot of sweat , they all ended up smashing their system, corrupting/removing critical system files and what they do after? then just reformat lol !!!
Curing take hours while a format + restore take around 15mn to get a clean system. do the math, answer is unavoidable , format always win.
Then you will point : "some people may have important files or programs" , and you are right , but did they do the basic step? which is backup their important files and software licenses in case of smashed system? if yes , format C: is the way to go.
Ask every IT repair guy, customers need their system operational ASAP , 99% of customers didn't care i format their system, they want it ready for yesterday. Not saying, longer it takes, more money they have to spend ... some people ask me a cure instead of a format because they lost *cough cough , keygened* the license for their softwares. Of course i charge them more.
If you believe that curing is better than format + restore, then nothing can be said anymore...so i will let you play with those support forums (which are not made to help you clean your infected system but fix issue with the soft)
