I have 4 instances of synchost.exe on my computer which run on startup and use up loads of memory, I have recently learned that synchost is considered a security risk, does it have any legitimate place on a windows system? and if not how do I get rid of it?

If you indeed have synchost.exe running,then you have an infection !! this we can deal with.

If you mean svchost.exe this is legit and needed for windows to operate correctly.

Ok,it looks like you have RIPJAC TROJAN!

Download and install Malwarebytes free click here


Superantispyware click here

Install both and update.

Now boot into safemode by tapping f8 on startup and select safemode (not with networking).

Run both programs and when finished boot back into windows...they should cure your problem.

Do you have antivirus installed and updated ? as this is an old trojan and should have been dealt with.

Yep... thankyou also !

I noticed you ticked this as resolved. I am sure the rest of us would like to know how, so we can learn lessons, and in particular let skidzy - a very knowledgable guy - know that his suggestion worked.

Good one skidzy, that's comprehensively cleared that one up!
