possible virus? random web page opening?

[PotNoodleHead]

Since last night i've noticed my web browser acting a little weird, a few times i've been blocked from going on a website via google (like facebook) saying its possible malware but if i go back and try again it works..

On occasion as well when i've duplicated a browser tab it displays a totally different website

Does this sounds like a virus?
since posting this i had a malware bytes, Eset NOD32 and a windows defence scan come back clear..

Sounds like one. Scan your computer and use a anti-virus software before its too late.

Install microsoft security essentials,when it is done do a full scan.It is free,and works great. Good luck
