The risk of adding people that adds you without any reason.

Hide the link, you can't post them on forum.
That's probably a virus, when you open the site it tries to save "Screen saver" (yea, right...) on your PC.
My advice regarding the guy: BLOCK AND REPORT.

Yeah, going to http://screensave.eu/ drops you on a "403 - forbidden" running on "Apache Server at: s1048465-33677.pa.infobox.ru". 100% scam link. So Good Job!

Also, you can install NoScript for Firefox or HTTP Switchboard for Chrome (set it to block by default) and be able to check those suspicious links yourself.

P.S. But generally strangers asking you to click on links should never be trusted anyway. I just usually check these links so I can feel confident when reporting the user to Steam Support.

Iirc it's a hotlink for a .scr file(windows executable typically used for for screensavers,but can be as dangerous as any .exe). Opening it will open up a basic empty gui window titled Form1 and run a most likely malicious script in the background that has no immediate visable effect(it might do something like upload your steamguard premission file to the attacker,letting him get full control over your account,but I couldn't confirm). An exceptional warning goes to those using a windows version below xp as .scr files would be automatically executed,meaning that if you don't have a download confirmation dialogue,merely clicking on that link would cause the malicious file to automatically execute without anything asking for your permission first.

First thing to do is to not accept private and low level profiles.

Just block and report buddy :)

links to virus/malware

please remove link from thread to protect people from trying to open it.

I thought I was safe of those random adds, but since Thursday I'm getting 1/day. Hope it doesn't increase.

Just minutes after writting this noticed a random add from someone with +100 games, so thought, may be someone from SG wanting to troll, let's accept what a human can say, result:

18:19 - Elder: hello
18:19 - Elder: why you added me?
18:22 - Elder: I'm doing the laundry, you have until I return to answer. Else you will be blocked and deleted.
18:23 - hE: :D i have a problem, and you cannot helkp
18:24 - hE: have 35€ on g2a.com now but i cannot buy FIFA
18:24 - hE: dont use this bastard website
18:24 - hE: im scammed ;D
18:30 - hE: finaly... i have 35€ on G2A and i need to buy FIFA 15 35,36€ hidden reflink to g2a
18:30 - hE: that just can be a joke
18:30 - hE: xD
18:55 - Elder: cool, but that doesn't answer why you added me
19:00 - Elder: ok will delete and block you
19:00 - hE: fast pls

btw the price on g2a is 33,99€ but I was not interested on how the conversation could advance.

Not necessarily an image. Probably a website that tries to attack certain browsers through some vulnerability that will allow them to steal your account or items or install a keylogger or something... Run steam in something like Sandboxie, don't use your browser to log into steam (if you have to log out asap), don't click on links in steam.. even if it's from a friend, copy the link then open a browser protected by something like Sandboxie and paste the link in. Don't add people you don't know to begin with...

Friend of mine lost ~$75 of his favourite dota2 items thanks to the exact same link.

Tell this guy to go f**k himself.

I always check their steam level and number of games before even considering accepting their friend request.

glad i found this, i've been getting tons of random FR's lately and been wondering if i should accept or not...just ignored em all now.

been getting 1-4 a day random adds, all saying "wanna trade some stuff for this skin? [ Random Link ]"

Well, I'm never going to add random invites ever again.

I accept these friend requests because I'm lonely and live in my mom's basement.

You never know what you're going to get out of a friend request.

The only risk is when you open a suspicious link they send you. To be on the safe side just don't open any links from people you don't know.

Lol, suddenly someone unknown appears and give me a link without reason, it's an instaBAN for me. Not blocking, though.

What i do always is, as soon as someone adds me, i put my own alias, so more or less i know who is he/she.
All my friends have my own alias. Examples: Random person, guy from Steamtrades, girl from pornotube, winner from Steamgifts, etc...

No problems so far ^ ^

Honestly I'm suspicious of them not wanting to say what the link is to. They may as well say "it's going to give you a virus/steal your account infomation/do something else harmful to your computer or account" because that is the likely result there.

the human say that it would add you with his/her first acc, that is obviously a scam attempt. legit traders don't have five thousands of accounts, or at least they don't tell you they have to switch accounts to make a trade.

oh and for the REPORT part, check his/her profile and select the little flag then fill up the form.

It's been happening a lot lately. Just don'r open any link from strange people.

Before adding or declining invites, just hover over their avatar and see what Steam level they are. Level 0 is an immediate block, and level 1,2,3 are highly suspicious but deserve a profile visit before declining.

I dealt with uninvited requests by adding a line to my profile. Anyone not taking the time to read my profile blurb (which is short) simply gets ignored. Problem solved.

i only add people i think are females cuz im a loser like that

Its kind of weird for me. I never used to have any problem with unwanted invites but then a month or two ago I made a joke over here about how I get no invites and poof I'm being spammed with invites ..... FML ...(T_T)

I think there was clearly a reason behind adding you there ;)

(causing you harm in some way)

I suggest you check each one that tries to add you and if they are level 0 with private account, report and ignore them. Don't bother blocking them because as I discovered they were still able to send me messages somehow. (blocked them, went to sleep, next morning there was 5 messages waiting for me from that blocked bot)
