After installing an antivirus, my computer logs me off automatically after log on. How can i fix thi

Which anti-virus are we talking about here? You could very well have downloaded a virus in place of an anti-virus. Here are the free and SAFE anti-viruses that can be used:

AVG Free

Avast! Home Edition

AntiVir Personal Classic

Comodo

PC Tools Free

ClamWin

ClamAV

Norton Security Scan

BitDefender 10.0 Free

Dr.Web CureIt Free

If you installed a freeware anti-virus and it's NOT one of these, then it's most probably a rogue product. Immediately uninstall it, and get AVG or Avast! from above. Install and update it and then run a full system scan. Never use more than one anti-virus as it can cause driver conflicts.

Lots of ways to fix it really... I am sure someone else here will be more helpful because I am just too lazy to type everything...
