Problem with internet and upload

[tdmm1990]

Hello

I have 6 Mb/s internet. Everything was ok, but now...

I can't display pages in Internet Explorer (but Opera works), Internet is slower, I can't upload anything (but download works) and I can't make test internet, cause I get this error on many sites (with test of upload and download): "License expired or invalid".

I reinstalled Windows 7, but it's still the same.

What should I do?

Thank you for help.

In IE
Go to tools
internet options
advanced
reset
This removes all add-ons which is probably the problem.

and

Run antivirus scan
If you can Download and run malwarebytes, full scan after update.

Reset couldn't help me, I did it. I scanned computer and use Combofix - it's still the same.

Did you use malwarebytes for full scan? Scan takes at least an hour.
Antivirus scan would take about as long.

It founds 4 rootkits and deleted it. I will restart my computer and check if it's ok.

I would go to the security section of the forum, rootkits are some of the worst and can hide.

My computer is now clear, but it's still the same.

Repost in the security section. I truly doubt that you are clear. Rootkits are bad. They remain hidden. Make sure that they are all gone.
