The client accuses of infecting sites. What to do?

Question

Malware

Guys, hello. I have such a situation - the client, apparently, does not want to pay the rest of the money for the work performed.
The essence of his first claims - "After your work, I had to clean my entire account from viruses."
Facts:
- At the very beginning, he himself said that he did not know why something might not work on his over 60 sites (because someone is constantly tinkering there)
- All this "happiness" is on the shared
- Many sites have engines and modules ( or whatever they are called in Joomla) have not been updated.
- It's just a wild mess in the files and a bunch of g * vnokoda that in self-written solutions, that on the site on cms (this tin really needs to be seen ... It's understandable, different freelancers are constantly picking on the sites)
- A month ago, she herself found a redirect from him on one site, which she informed him about.
From my side everything is 100% clean. To prove to him his innocence in terms of the fact that I have more than 20 sites on support and at least 10 more pass every month is low.
On principle, I want to prove my innocence.
What to do? Requesting logs from the host is pointless.

Answer 1

On principle, I want to prove my innocence.

Useless. You will not prove it, you will only lose time / money and nerves.
To understand and to forgive. (C)
To score and NEVER do again on customer hosting UNTIL full payment.
Consider that you bought the mind.
APD . In general, if there is a contract, then you need to read it. If there is an obligation of the client to pay for the work and there is nothing about viruses, etc., you can get in trouble.
But there is no contract - alas.

Answer 2

1) Try to ask him for specific arguments why he thinks that you infected him.
Ask how exactly you infected him. What kind of viruses.
And then there is logic. I washed the car - it started to rain... magic...
2) Point out that the solutions he uses are not safe (because they are...) and are potential holes, ask him to explain why he is sure that they are not the source of infection .
3) In short, give your expert opinion. If he does not understand, then let him not make claims in what he does not understand, or let him try to figure it out and answer all your questions.

Answer 3

blame him. for example, say that you will have a child with him.

Answer 4

Say goodbye to the client. Take care of your nerves and do not substitute.

Answer 5

Fuck send such a client. I would not work with such clients for any pay.

Answer 6

You don't need to prove anything. Under criminal law, the guilt of the accused must be proven, and not vice versa. You can write that communication on the part of the client has gone beyond the boundaries of acceptable business ethics, and therefore further cooperation is immediately terminated. Add that if there are threats or any ambiguous hints from his side, you reserve the right to contact the law enforcement agencies of his country (you can leave a statement to the local police through the site).
If you have a signed contract, then you can contact law firms (there are in every country). They will write exactly one letter to the client for a percentage of the debt, and within a couple of days you will receive a debt transfer. You should not be afraid of this, but write that you expect full payment of the debt on the date specified in the contract.
For the future, always write in the contract that the work performed remains your property until the full payment of the entire amount, including all penalties. Penalties under the contract should always be and should grow very quickly, so that even the idea does not arise not to pay for the work. Mention in the contract that the collection of debts can be transferred to debt collectors, in which case the client undertakes to pay all arising costs.
It doesn't matter to a normal client if he plans to pay, but a crazy client gets scared and runs away. It will be a useful filter for you.

Answer 7

I support the speakers above - it is useless to butt heads and prove. The client was going to throw money, nothing will stop him here.
Depending on the further impudence of the client, I would ensure that I can access his sites, regardless of the client changing passwords. And when everything settles down, in a month or two or three, I would quietly drop several sites to the client. First, a little, and then in a serious way, with garbage being written to all files on the hosting. It is desirable to do this in the evening, so that the downtime time is maximum. If it is possible to break backups, you can first break backups, wait until the history of storing backups turns sour, and go ahead ...
In principle, statements about the "90s" are already quite enough for my personal conscience to turn aside for a while carrying out the activities described above.
