I have had a problem with internet access gradually slowing down after a reboot, also downloads slow & often corrupt. I have traced this to Steganos Security Suite, although everything was fine initially after install, after a few weeks this problem appeared, I have not removed the program but disabled slee503.exe which is part of it, that has fixed things. It also appears to increase processer use as internet use increases.

Any idea why slee503.exe might cause this.

PS I had the same problem with Steganos Internet Anonym, fixed by un-instaling

Are you running any other firewall or antivirus?

Have seen many issues with Steganos not tollerating any other security software.
