Hello security analysts,
A few weeks ago on this machine I downloaded a freeware program that I was going to use to convert .flv's to .whatever. Unbeknownst to me, this was your typical freeware loaded with a bunch of garbage during the install, and I X'd the install rather than clicking anything else (friendly tip from Corrine that I never forgot!) before it installed any of its other stuff and just moved on. The mistakes I make when I'm tired....
After uninstalling it and restarting and ensuring it was gone + any remnants, I ran a MBAM scan and had a PUP in my TEMP. I figured it was just something it dropped in there that it 'would' have executed if I kept going with the installation. Needless to say I cleared my TEMP, restarted, ran MBAM again and it didn't show up.
Well, I ran MBAM again a bit ago just to do my biweekly scanning and it found 2 PUP's in TEMP again:
With this said, I did the same thing.. just cleaned TEMP, restarted, ran a Quick Scan again and they were gone the next time (here is the log right after the cleaning TEMP and restarting):
(To clarify when I say 'I cleaned TEMP' I didn't take any action with MBAM, I just used it as a scanner. I flushed my temporary files myself, restarted, and then scanned again afterwards and they were gone).
I then ran a Full Scan with MBAM and that was clean as well, here's the log:
Given that they are not reappearing after a cleaning of TEMP and rescanning (or new ones), there is no obvious decrease whatsoever in system performance, all processes are regular and none are sketchy, etc, would you say that these PUP's that I sometimes see in scans are just sometimes being caught from browsing the occasional not-so-safe website, and I am not infected and these are being dropped in there by a trojan, let's say?
Regards,
Patrick
