After a virus injection on my website, i had a problem with this extension (404 problem, virtuemart plugin impossible to install) I payed the support, urgent, so I payed 30 euros more.
After 24 hours nothing changed, and the said that i had a database problem that needs more than 1 hour to solve it. I've asked how long they think it takes, and they reply (after 1 day!!!) that it takes 3-4 hours. It seemed so strange to me, to patch a database 3-4 hours?? So, after another day, and searching like a mad, i found the solution just here on this website, in the forum: disinstall, cancel the tables in the database, reinstall and DISABLE JF ROUTER PLUGIN.
So simple as that. 5 minutes work if you know what to do.
I payed 65 euros to have a quick solution to my problem, and at the end i did the job myself after 3 days of searching and getting mad.
This is Artio payed support.

Sir,
if you had a virus injection, difficult to say what was destroyed. Yes, it could take 15 min. but also 3 hours .. who can knows
