This is what an ex-engineer with Mozilla foundation says.
He has made a detailedblog poston why installing third-party antivirus solutions are really bad for your rig.
You misunderstand your own ignorance.
AV is my single biggest impediment to shipping a secure net surf tool.
He said that due to AV products effect, users tend to believe that browsers are bad.
The AV products also block important security updates which can put the users computers to risk.
Several times AV software blocked Firefox updates, making it impossible for users to receive important security fixes.
Robert has a point, though.
The AV products are resource hungry, eat a lot of storage space and slow up RAM.
They also make computers somewhat sluggish and sometimes block legitimate software by flagging them.
They also make installation of drivers a bit difficult.
