norton recently found and resolved 5 high-risk trojans on my system:
f.class
vmain.class
patchers.class
cloners.class
debuggr.class
I don't know where these came from, and other people say that they have found them also, in this group. Afterwards, i ran malwarebytes scan in safemode and also it found 5 more infections.
How do I know if my system is safe and clean? Where did these trojans come from, and should I be worried? Why didn't norton block them in the first place?
I had the virus Tidserve. a month ago, and used the zip file tidservekiller to remove it. could it be remnants of that?
please let me know whether it is actually resolved, or whether i need to take action.
