is site infected?

While downloading the Sudoku Solver script .zip file Windows gave me a warning that Explorer was being accessed in a threatening way. (Sorry I forget the exact warning message.)

Windows completely froze and I had to do a power-off then restart.

I'm suspicious of the pop-under that was open at the time. (And yes I really DO NOT like the pop-unders!)

I reopened FireFox and looked at History, most recent pages.

The last pop-up - the one I saw when the system froze - had a page title was "Love Compatibility Calculator - Match your name ..."

The url was: http://mobularity.net/usluvcompatibility/indexname.php?carrierstyle=bp&sess=2&ref2=valcpa&utm_source=val&utm_medium=cpm&ref4=split&

Anyway, I don't know if this is the problem but it is very suspicious.

Does your site really open pop-under ads? If so, isn't there a better way to generate revenues?

Does you pop-under ad server run a rigorous anti-virus screening?

Thanks

The Soduku Solver or any other classes do not contain harmless files because the site only allows verified text, HTML, image and Flash files.

I suspect that pop-under that you clicked loaded a page that may have triggered high memory consumption by your browser or some kind of misbehaving extension.

The site places pop-under ads served by Tribalfusion or ValueClick ad agencies. These are reputed ad agencies. They are not expected to serve virus. Otherwise the site would not work with them.

Pop-under or any kind of advertising is annoying. Unfortunately it is necessary to keep viable a busy site like this.

Since several people complained and requested accessing the site without advertising, in July it was launched a package of premium subscription services.

These are exclusive services made available to subscribers that pay a small fee of USD $5 a month (or USD $4 a month if paid annually).

Among other services, it is included the possibility to access the site without advertising.

If you are interested, take a look at the premium services page. From there you can order a premium subscription or even try it without paying for a few days.

By the way, not exactly related to the ads problem, but if you work providing PHP consulting or other professional PHP services, and you become a premium subscriber, you can also get listed as a featured professional in this PHP professionals directory. That may help you get more PHP work:
