Hacked?

password change to be sure

Don't ever trust links, especially trade links , the scamming bots usually use a line like "you won a csgo item, open the link" or "a old friend is trying to add you on steam but can't find you, follow this link" stuff that like that you should always avoid clicking.

Should have told him to put it on PasteBin. You'd never get infected from a PasteBin link.

while i normally say avast sucks, it's probably a file that infects office or whatever opens it, i wouldnt think much of it IF the url was truly google, it's like downloading a virus without running it, it doesnt do anything

maybe you should submit the url or file to virus total, examine it a bit & have multiple scanners give it a name

Luckily you didn't run the executable since the avast blocked it on time. You have nothing to worry about in this case, however you have to be extra careful in the future :)

Why not open such a link in a sandboxed browser (i think sandboxie could also help preventing damage).

Q: You are showing your inventory to everyone - isn´t this the danger source ? With 27sites in your inventory maybe you are a most searched victim for bad people

My advise, if you want to trade DON'T OPEN ANY LINKS that you receive from the other guy, DON'T ACCEPT any private profile, and if you did this , then change your password immediately ;). Also report them with any occasion, maybe we will get rid of them :)

Have fun with your trades ;)

Well, if I get it well, you clicked on an evil link, AVAST detected the threat and blocked it, right ? Then you should be safe from that. I guess there's an option to reboot the computer and make the antivirus do a full PC scan, if you want to do some security check.
The totally secured computer is in a locked room with no netword access. And it is shut down !

Just change your password. No need to overdo it. If you have a two-step authentication (email or Steam Mobile Guard), some random dude using some trojan downloaded from 4chan won't really do anything.

I think, that if you dont open it, nothing wrong happened....i always click on links from all messages, even when i am almost sure, that is just another try to scam, but my browser always ask where to download, so i always cancel it, if i see some image.scr and then report on steam. Still nothing happend, never lost Steam account.
But never got something like Google Docs

Some useful advice from me this time: always make some check-out questions with trader to avoid bots. "Do you like roses"? for example. It's rare from bot to answer.

formatting sounds like a good advice

btw love your profile pic, time to get Schwifty :P

Formatting is always the safest thing you can do.
HOWEVER
if you haven't done that yet, you can do another check:

• Open cmd with admin rights (right click, run as admin).
• Close your browsers and anything with obvious nternet connection
• Type "netstat -ano"
• Check for all ongoing connections
• Compare the PID with the PIDs in task manager (theres a column for it)
• You can see if there are suspicious programs with an internet connection
• 80-95% of all keyloggers and trojans will be found that way

Also. Type in ^^
If you have to type it twice, as usual, everything is fine. If you hit the key once and both ^^ come up, it's a sign for a keylogger.

Change your passwords from a different PC aswell :)

Hope I could help you a little, if you have any other questions, your welcome :)

if avast warned you and you let it do it job, in theory it catches the "malware" before it go to the ram, so you should be safe... do you have steamguard activated? that its an extra protection

Hello. You must change your steam password too. Maybe do a search for files that your pc downloaded this day, because you never know what files may be lurking inside your pc. And of course, never click on any links. There are also links that are similar to steam links, like steamcoNmunity (I wrote N in caps on purpose, in order to see that there's a different letter). Also, Avast is a free antivirus, right? May I suggest that you'll use a professional antivirus to do the search, because maybe a free Antivirus isn't good enough (I don't know, but I'm saying it in order for you to be 100% sure that everything is ok).
