Hmm, this is an interesting one...
Guess you already flushed cache and cookies?
I don't see how our site would be affected but you can also try flushing the 'Flash cookies' or 'deep cookies', they are buried in the PC not the browser. You'll need CCleaner:
CCleaner - Download
Get the free version. Resist the temptation to delete stuff in the registry unless you know what you are doing.
Try another browser and see what happens. If necessary, download another one just for checking this kind of thing, it's useful. Here are some you can try (I don't know which one/s you have, or that you are currently using):
Firefox
- the best toolset (plugins), lots of things you can add to it to enhance functionality. Be aware this slows it right down though. Also streets ahead of all others for webapp/server admin.
ONLY download this via Mozilla - nowhere else.
Opera
- very good fast browser. Keep it skinny - no plugins - just for the speed. Excellent speed-dial (visual bookmark) system for fast site access when history is scrubbed. Weird JS engine means server admin is not good.
SWare Iron
- a spyware-free version of Chrome). Basic, skinny, good privacy. Everyone needs this installed for occasional use, if only just to check their normal browser.
Others:
Chrome: fine if you are OK with telling Google everything you do
Safari: main use is for geeks trying to do things other browsers don't
K-Meleon: used to be quick as it's so skinny, the JS engine is useless now
-------------------------
Don't use Adobe apps like PDF Reader, they are way too slow and have too many exploits. Use PDF-Xchange Reader. Uninstall Adobe PDF Reader, it's too dangerous to keep on a PC.
Update Java using the Java Ra app, it does the whole job including removal of risky old Java versions and installers. If you don't use Java Ra, you can still be vulnerable.
Use a real firewall such as Online Armor. A firewall needs to work in both directions - in AND out - or it's not a firewall. OK, it's a pain to teach it what to block / not block, but that's security: more security = less ease of use.
Once you have a real firewall, block ftp.exe in the firewall rules. It's only used by malware phoning home.
If you want to know what to trust or not trust, go to Gizmo's Freeware.
Don't google it, use Scroogle. The only link you need:
