My computer has lost some functionality...

[dajjrus]

Hi, my computer is acting weird and is getting worse every day. My homepage toolbar looks different, I dont have forward and backward keys, tabs dont work the same, some words are getting cut off, I have trouble navigating in some sites, my email switched to Outlook by itself, some sites tell me I dont have Java or Flash player installed, but I do, etc...I own a 3 year old e-machine T6528 with Widows XP Home. I have the free versions of AVG anti-virus and Comodo firewall and their scans come up clean..... HELP!!!

Try this: Trend Micro Housecall

Sounds like a virus/rootkit that is messing with your computer. If the above does not solve your problem, please post in the "Viruses/Spyware" section of the website, some capable computer technicians can assist you there.

Have you tried re-installing IE?
