How I turned a junker PC into a trap for scammers

As my regulars will be aware, for the past few weeks I’ve been getting lots of phone calls from “Peggy” from “Computer Maintenance Department.” What I’ve found during these phone calls is that debating with them does no good, and saying that your computer is crazy fast gets them to hang up on you, but they’ll call back again in a few days anyway.

Last week, I had lunch with a group of future coworkers–I’ll be joining them once my background check results come in–and I mentioned these phone calls. The guy sitting across the table from me said he wants their malware, so he can reverse-engineer it. So I said I would cooperate the next time I got a phone call. Read more

This “Computer Maintenance Department” sure doesn’t know much about computer maintenance

“Peggy” from “Computer Maintenance Department” (1-645-781-2458 on my caller ID) called again. Lots of people are aware of these phone calls. They call, make vague claims about receiving a report that your computer is running slow and giving you errors, and are very careful not to say who they are or who they work for. Usually I just do whatever I can to get them off the phone.

But after having lunch with some other computer security professionals last week, a couple of them talked me into finding out how these guys operate. So I fired up a PC that turned out to have a real, legitimate issue. After resolving that issue myself, I turned the caller loose on my semi-functional PC so I could see what these scammers actually do. He had me connect to Teamviewer.com and run their remote access software. I followed his instructions, watched him connect, then slyly unplugged my network cable.

When my network connection dropped, “Peggy” quickly transferred me to a “senior technician” who used the name “Roy.” Read more

Antivirus progress

Dave Farquhar security May 14, 2013May 12, 2013antivirus, avast, bitdefender, Microsoft Security Essentials, pc magazine

When Microsoft Security Essentials first came out, it was an improvement in antivirus performance. Now, it’s middle of the pack, according to PC Magazine. That’s great. Vendors are finally taking performance seriously.

What that means is that by replacing MSE with F-Secure Anti-Virus 2013, Kaspersky Anti-Virus (2013), Sophos Anti-Virus 10.2, ESET NOD32 Antivirus 6, Norton Antivirus (2013), Avast Free Antivirus 8, or Bitdefender Antivirus Plus 2013, you can speed up your computer. Considering Norton Antivirus was once bottom-of-the-barrel in the performance arena, I see this as a good thing.

Of the bunch, Avast is the only freebie. Though if your ISP offers one of the others as part of your subscription, or you don’t mind paying for antivirus, the others are an option. But maybe, just maybe, if I replace Microsoft Security Essentials with Avast, Peggy will quit calling me at dinnertime and telling me my computer is slow. But I doubt it. Read more

Bitdefender 60-second virus scan: a review

Dave Farquhar security March 14, 2013November 30, 2015antivirus, avast, bitdefender, firewall, malware, spyware, trojan horse

I mentioned Bitdefender 60-second virus scan the other day, but didn’t give it a proper review. It’s time I remedy that.

It’s a small 160K stub that downloads a few more megabytes worth of stuff after you run it. Unlike most other free antivirus apps, this one is intended to be secondary–a marketing tool to show you what your primary antivirus isn’t catching that Bitdefender would, I suppose. But I think it’s useful as a second line of defense, and recommend using it as such.

Ars Technica made a bit of a splash this week with this provocative headline. This is real.

The article gives the usual advice, like not opening e-mail from strangers, not clicking attachments from strangers, and not visiting dodgy websites. That’s all good advice, as is staying off torrent and other file sharing sites, but even all that is not enough.

Avast 8 is out and already well-regarded

Dave Farquhar security March 2, 2013March 1, 2013antivirus, AV, avast, defense in depth, firefox, malware

Avast 8 is out, and the initial reviews are positive.

If you use Avast, either as your primary or as your secondary AV, updating it is a good idea. One critical improvement is that virus database updates happen more frequently now. There’s no such thing as too frequently when it comes to database updates.

Mobile malware is coming. Get prepared.

One thing I’m seeing in the predictions-for-2013 columns is that mobile malware is going to increase this year. While I can’t be certain it’s going to happen, all of the ingredients are there. The only thing stopping it is motive.

I’m familiar with Avast antivirus on Android. It’s nice. Whenever I download an app from the Google Play store, it scans it, and if it finds something it doesn’t like, it intervenes. Read more

How to schedule scans with Avast (even the free version)

Dave Farquhar security December 20, 2012antivirus, avast, defense in depth, performance penalty

Scheduling scans with Avast is easy, as it turns out, if non-obvious. Launch Avast, then, non-intuitively, click Scan Now. Click Settings, then, buried on the left is an option called Scheduling.

I recommend doing a quick scan at least once a day and a full scan at least once a week. If you’re using Avast as a secondary scanner, be sure to have your primary scanner scheduled to perform scans too. Read more

Get defense in depth with antivirus by installing Avast as a secondary scanner

Dave Farquhar security December 13, 2012December 5, 2015antivirus, avast, chrome, defense in depth

Two antivirus programs on one system? Heresy, right?

Well, not if one is designed to play second fiddle. As it turns out, Avast, one of the best free antivirus programs, can do just that. Just download it, run the installer, and pick the second option–“Compatible install – install as the second line of defense.” Be sure to de-select the option to install Google Chrome and make it your default browser, unless you want that. Free programs often come with ridealongs.
