"Best A/V app period, will not use any other"
IF u set all expert settings in shields on high, & set scan on high, activate Auto sandbox & make sure Avast self defense module box is checked, u won't get any viruses on ur PC.I've used Norton got a virus, AVG ditto, in 07 or 08 I tried Avast, NONE since.Something I've never done before or since is send a personal thank u to Avast 4 this great app.
never a problem except having 2 reinstall it every year.
